StitchPartner stocks genuine replacement motors compatible with Usha, Janome, Singer, Brother, and industrial lockstitch machines, with pan-India delivery and Cash on Delivery available.\r\n<h2>Sewing Machine Motor Price in India<\/h2>\r\nSewing machine motor price mainly depends on motor type, power rating, and whether it's built for home use or continuous industrial operation. At StitchPartner, domestic carbon motor sets with a foot pedal \u2014 the standard replacement for Usha, Janome, Singer, and Brother home machines \u2014 start from around \u20b91,199 and go up to about \u20b91,650 for heavy-duty sets. Carbonless (brushless) domestic motors, which run quieter and need less maintenance, are priced around \u20b92,000. Industrial and semi-industrial servo motors, built for continuous use on lockstitch and overlock machines, range from roughly \u20b92,899 to \u20b93,199 depending on wattage and control features.\r\n\r\nThese prices reflect StitchPartner's current catalog and can change with supplier costs \u2014 check the individual product page for the latest price before ordering.\r\n<h2>Servo Motor vs Clutch (Carbon) Motor \u2014 Which Should You Buy?<\/h2>\r\nThe two main motor types differ mainly in how they run and what they cost to buy and operate. Clutch (carbon) motors spin continuously whenever the machine is switched on, and stitching speed is controlled by how firmly the clutch is engaged through the pedal \u2014 they're simple, robust, and generally the cheaper option to buy. Servo motors only run when the pedal is pressed, giving finer speed control, a quieter workshop, and lower electricity use over a full working day, which is why most professional tailoring units and factories have shifted to servo motors despite the higher upfront price.\r\n\r\nFor an occasional home user stitching a few hours a week, a carbon motor is usually enough. For a boutique or factory running machines for eight-plus hours a day, the extra cost of a servo motor is typically recovered through lower power bills and less noise fatigue within a few months.\r\n<h2>Which Motor Fits Your Sewing Machine?<\/h2>\r\nMotor compatibility depends on your machine's mounting bracket and pulley size, not just the brand name. StitchPartner's <a href=\"https:\/\/stitchpartner.com\/product\/sewing-machine-motor-usha-janome-singer-brother\/\">sewing machine motor for Usha, Janome, Singer &amp; Brother<\/a> is built for standard domestic machines from these brands. For industrial lockstitch, overlock, and interlock machines, a standard servo motor is the usual replacement. If you're not sure which motor your machine needs, confirm your machine's brand and model number with StitchPartner support before ordering so the right motor and pulley size can be matched.\r\n<h2>Signs Your Sewing Machine Motor Needs Replacing<\/h2>\r\nA motor is usually due for replacement when the machine runs unevenly despite consistent pedal pressure, makes a burning smell or grinding noise, overheats after short use, or fails to start even though the wiring and foot pedal are working. Carbon motors specifically lose power as their carbon brushes wear down \u2014 a common issue after a few years of heavy use \u2014 while servo motor faults are more often in the control board (PCB) than in the motor coil itself.\r\n<h2>Reliable Parts for Long-Term Use<\/h2>\r\nWhether you're replacing a worn component or upgrading your motor system, you'll find dependable options here. From foot pedals and pulleys to carbon brushes, control boards, and wiring, our parts help extend the life of your sewing machine without hassle.\r\n<h2>Why Buy Sewing Machine Motors from StitchPartner?<\/h2>\r\nStitchPartner supplies genuine sewing machine motors, spare parts, and accessories for both home and industrial machines across India. Orders come with pan-India delivery and Cash on Delivery on eligible orders, and GST invoicing is available for bulk and wholesale buyers such as tailoring units and garment factories.\r\n<h2>Frequently Asked Questions<\/h2>\r\n<h3>What Is the Price of a Sewing Machine Motor in India?<\/h3>\r\nSewing machine motor prices in India typically range from about \u20b91,199 for a domestic carbon motor set to around \u20b93,199 for an industrial servo motor. Basic replacement parts like a motor pulley or foot pedal switch cost much less, usually under \u20b9500, while a full motor-and-pedal set for a home machine averages \u20b91,200\u2013\u20b92,000.\r\n<h3>What's the Difference Between a Servo Motor and a Clutch Motor?<\/h3>\r\nA clutch (carbon) motor spins continuously and controls speed through pedal pressure on a clutch, while a servo motor only runs when the pedal is pressed and offers finer, quieter speed control. Servo motors cost more upfront but use less electricity over a full working day and are the standard choice in factories and busy tailoring units; clutch motors remain popular for occasional home use because they're cheaper to buy.\r\n<h3>Which Motor Is Compatible with Usha, Janome, Singer, or Brother Machines?<\/h3>\r\nStitchPartner's domestic sewing machine motor is built to fit standard Usha, Janome, Singer, and Brother home machines using the common foot-pedal-and-motor mounting used across these brands. If your machine has a non-standard mounting bracket or an older model, confirm your machine's model number with StitchPartner before ordering to avoid a mismatch.\r\n<h3>Is a Servo Motor Worth the Extra Cost Over a Carbon Motor?<\/h3>\r\nFor daily, extended use \u2014 boutiques, tailoring units, and garment factories \u2014 yes: the quieter operation, finer speed control, and lower running electricity cost usually justify the higher upfront price within months. For occasional home stitching, a carbon motor is usually the more economical choice since the machine isn't run long enough each day for the electricity savings to matter as much.\r\n<h3>Can I Replace a Sewing Machine Motor Myself?<\/h3>\r\nReplacing a sewing machine motor is a straightforward job for anyone comfortable with basic tools \u2014 it mainly involves unscrewing the old motor bracket, transferring the belt\/pulley, and reconnecting the foot pedal wiring. If you're not confident with electrical connections, it's safer to have a local sewing machine mechanic do the swap, which usually takes under 30 minutes.","parent":0,"count":36,"filter":"raw","image":""},{"term_id":1103,"name":"Sewing Machine Motherboard &amp; PCB Control Boards","slug":"sewing-machine-motherboard-and-chip","term_group":0,"term_taxonomy_id":1103,"taxonomy":"product_cat","description":"<p><strong>Sewing machine motherboard and PCB control boards for industrial machines:<\/strong> main boards for Jack, Qi Xing, Zoje, Messer and Magneto machines cost \u20b91,500 to \u20b94,650 in our live catalogue, with display panels and pedal boards from \u20b9300.

Read the part number on the old board<\/h3>\n<p>Unplug the machine, open the control box and read the number printed on the green board. Order that exact number. For Jack machines you can also check our <a href=\"https:\/\/stitchpartner.com\/jack-sewing-machine-part-numbers\/\">Jack sewing machine part numbers lookup<\/a>.<\/p>\n<h3>2. Check the generation of the board<\/h3>\n<p>Some machines have an old type and a new type of the same board, for example on the Jack F4 line. Their connectors and firmware can differ, so match the type, not just the model name.<\/p>\n<h3>3. Compare connectors and voltage<\/h3>\n<p>Count the connector sockets and compare their layout with the old board. A board can physically fit and still lose trimmer, foot lifter or display functions if pins are missing.<\/p>\n<h3>4. Send us a photo before you order<\/h3>\n<p>If you are not sure, send a photo of the old PCB and the machine model. We check the match first, so you do not pay for a board that will not work.<\/p>\n<h2>Motherboard, PCB, Control Board and Control Box: What Is the Difference?<\/h2>\n<p>Buyers use these words for the same part, but a control box is the casing that holds the PCB, the power supply and the connectors. A motherboard replacement is only the board inside. If your control box is damaged or burnt, ask us whether you need the board alone or the full box such as the <a href=\"https:\/\/stitchpartner.com\/product\/direct-drive-servo-motor-control-board\/\">direct drive servo control board<\/a>.<\/p>\n<h2>Signs Your Sewing Machine PCB Has Failed<\/h2>\n<p>A failing board usually shows erratic motor speed, no reaction to the foot pedal, a frozen or blank display, or no power despite a good socket. Before you buy, rule out a loose pedal wire or a faulty motor. Our guides on <a href=\"https:\/\/stitchpartner.com\/sewing-machine-servo-motor-problems-error-codes-troubleshooting\/\">servo motor problems and error codes<\/a> and <a href=\"https:\/\/stitchpartner.com\/jack-sewing-machine-error-codes-all-models\/\">Jack error codes for all models<\/a> help you tell a board fault from a motor fault.<\/p>\n<h2>Sewing Machine Motherboard FAQ<\/h2>\n<h3>What is the price of a sewing machine motherboard in India?<\/h3>\n<p>Main PCB control boards in our catalogue cost between \u20b91,500 and \u20b94,650, depending on the machine. Jack A2B is \u20b92,900, Jack 781G is \u20b94,650 and Qi Xing QD8633 is \u20b93,100. Display panels and pedal boards cost less, from \u20b9300. Prices on this page are live catalogue prices and COD is available.<\/p>\n<h3>How do I know which PCB fits my sewing machine?<\/h3>\n<p>Match the part number printed on your old board, not the machine's looks. Then compare the connector layout and the voltage rating, and check whether your board is an old or new type. Our stock list above shows the part number for each board, so you can compare it before ordering.<\/p>\n<h3>Can I use a universal or generic PCB instead of the original?<\/h3>\n<p>A universal board works only where its connector layout and functions match your machine, for example the direct drive servo control board for servo motors. For machines with auto trim and sensors, a model-specific board is safer, because a generic board may not drive every function.<\/p>\n<h3>How do I know if the PCB is faulty and not the motor?<\/h3>\n<p>If the motor runs only at full speed, stops at random, or ignores the pedal while the pedal and wires are good, the board is the usual cause. If the machine has no power at all, check the plug, fuse and power cable first. When in doubt, send us the symptoms and the machine model.<\/p>\n<h3>Are Jack A2B and Jack A2C PCBs the same?<\/h3>\n<p>No, treat them as different boards. Jack A2B uses part number 19510031200, while the A2-CZ board uses 9950014900. Both are in stock here, so compare the number on your old board before you order. Do not swap them just because both belong to the A2 range.<\/p>\n<h3>Do you deliver sewing machine motherboards across India with COD?<\/h3>\n<p>Yes, we ship pan-India and COD is available on these boards. Check the product page for the live price and stock status before you place the order, since stock changes through the day.<\/p>","parent":0,"count":42,"filter":"raw","image":""}],"product_tag":[{"term_id":3582,"name":"direct drive sewing pedal","slug":"direct-drive-sewing-pedal","term_group":0,"term_taxonomy_id":3582,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3580,"name":"electronic foot controller","slug":"electronic-foot-controller","term_group":0,"term_taxonomy_id":3580,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3572,"name":"electronic sewing machine foot pedal","slug":"electronic-sewing-machine-foot-pedal","term_group":0,"term_taxonomy_id":3572,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":2499,"name":"Garment Machine Spare Parts","slug":"garment-machine-spare-parts","term_group":0,"term_taxonomy_id":2499,"taxonomy":"product_tag","description":"","parent":0,"count":9,"filter":"raw","image":""},{"term_id":3573,"name":"industrial overlock foot pedal","slug":"industrial-overlock-foot-pedal","term_group":0,"term_taxonomy_id":3573,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3579,"name":"industrial sewing machine pedal","slug":"industrial-sewing-machine-pedal","term_group":0,"term_taxonomy_id":3579,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3576,"name":"Maimin S3 pedal","slug":"maimin-s3-pedal","term_group":0,"term_taxonomy_id":3576,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3577,"name":"Maimin S4 pedal","slug":"maimin-s4-pedal","term_group":0,"term_taxonomy_id":3577,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3143,"name":"overlock machine parts","slug":"overlock-machine-parts","term_group":0,"term_taxonomy_id":3143,"taxonomy":"product_tag","description":"","parent":0,"count":3,"filter":"raw","image":""},{"term_id":3578,"name":"overlock machine pedal","slug":"overlock-machine-pedal","term_group":0,"term_taxonomy_id":3578,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3581,"name":"sewing machine speed regulator","slug":"sewing-machine-speed-regulator","term_group":0,"term_taxonomy_id":3581,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3583,"name":"sewing speed controller","slug":"sewing-speed-controller","term_group":0,"term_taxonomy_id":3583,"taxonomy":"product_tag","description":"","parent":0,"count":2,"filter":"raw","image":""},{"term_id":3574,"name":"speed control foot pedal","slug":"speed-control-foot-pedal","term_group":0,"term_taxonomy_id":3574,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3571,"name":"SUPU foot pedal","slug":"supu-foot-pedal","term_group":0,"term_taxonomy_id":3571,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3575,"name":"SUPU speed controller","slug":"supu-speed-controller","term_group":0,"term_taxonomy_id":3575,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.8 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>SUPU Electronic Speed Control Foot Pedal for Overlock - Stitch Partner<\/title>\n<meta name=\"description\" content=\"Buy SUPU electronic speed control foot pedal for compatible industrial overlock machines.
