EMG Product Lines We Repair
Our engineers are trained on the full EMG product range. Below are the major product families we service.
EMG Stepper Motor Drives (SMGP, SMGT, SMGR series)
Compact step/direction and pulse-mode stepper motor drivers for textile machinery, winding systems, and precision feed applications. Common faults include encoder signal loss, phase winding faults, and overvoltage damage from supply surges. Repair involves motor winding resistance checks, shaft encoder diagnostics, and power stage MOSFET replacement.
EMG Servo Amplifiers (SA series)
Closed-loop servo amplifiers for synchronous motor control in printing, labeling, and converting machinery. Typical failures: analog input offset drift, velocity loop instability, temperature sensor malfunction, and capacitor degradation. Synchronics recalibrates EMG servo loop parameters and replaces aged electrolytic capacitor banks.
EMG Motion Control Modules (MCM, MCP series)
Programmable motion controllers for multi-axis coordination in packaging lines, textile looms, and assembly equipment. Common issues: firmware corruption, real-time clock battery depletion, relay output failures, and CAN/serial communication timeouts. Repair includes firmware reloading, PCB relay replacement, and communication protocol verification.
EMG Encoder Interfaces (EIH, EIS series)
High-resolution incremental and absolute encoder signal conditioning modules for feedback loop stability. Prone to signal crosstalk in noisy environments, power supply noise injection, and differential line driver burnout. Synchronics isolates analog/digital circuits, replaces signal conditioning ICs, and performs loop stability testing.
EMG Stepper Motors (EMST, EMSO series)
Two-phase and three-phase stepper motors rated for continuous and intermittent duty in Indian textile, printing, and food processing industries. Failure modes: winding shorts from moisture ingress, bearing seizure from contamination, and shaft key slippage under overload. Synchronics rewinds motor coils per EMG specifications and replaces cartridge bearings.
EMG Power Supply Modules (PSM, PSB series)
Regulated DC power supplies and battery backup modules for stepper systems and servo amplifiers. Typical faults: primary transformer core saturation, rectifier diode failure, voltage regulation IC drift, and electrolytic capacitor bulging. Synchronics performs high-voltage isolation testing and replaces power semiconductors with EMG-qualified parts.

Common EMG Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EMG equipment arriving at our workshop.
- ✓Stepper motor phase winding open circuit — Thermal overstress from continuous high-current operation, moisture-induced insulation breakdown, or manufacturing defect in phase coil windings. Common in Indian textile mills operating in high-humidity environments without adequate motor cooling.
- ✓Stepper drive output transistor short circuit — EMG stepper drivers use discrete MOSFET H-bridge power stages; thermal runaway, gate-source dielectric failure, or ESD damage from improper cabling cause transistor shorts, which then draw excessive current from the supply.
- ✓Servo amplifier velocity feedback oscillation — Encoder cable shielding degradation, ground loop formation between amplifier and motor, or PI loop tuning drift over time cause 500-2000 Hz oscillation in closed-loop servo control. Affects print registration and winding tension precision.
- ✓Motion control module CAN bus communication timeout — EMG MCM/MCP modules use CAN 2.0B for multi-axis synchronization. Failure occurs from CAN transceiver IC damage, termination resistor mismatch, or firmware corruption preventing handshake protocol execution.
- ✓Encoder interface signal dropout under acceleration — EMG EIH/EIS encoder conditioning modules suffer signal loss when motor acceleration exceeds 1000 RPM/s due to insufficient low-pass filter cutoff frequency or power supply noise injection during PWM switching transients.
- ✓Power supply module output voltage sag under transient load — EMG PSM/PSB modules use single-stage LC filtering; inadequate capacitor bulk capacitance or ESR increase over time causes 5-15% voltage droop when stepper motor currents switch from idle to full-rated load.

All repairs are performed in our ISO 9001 certified facility in Vadodara, Gujarat, with same-day turnaround for critical repairs.
What is the typical turnaround time for EMG stepper drive repair?+
Standard turnaround for EMG stepper drives is 3-5 working days including component procurement, repair, and functional test. Critical repairs for running production lines receive priority — we can often complete SMGP/SMGT series repairs in 24-48 hours. Express courier both ways is included at no extra charge for Indian cities.
Can Synchronics repair EMG motors with burnt windings?+
Yes. Synchronics specializes in EMG stepper motor rewinding for EMST-23, EMST-34, EMSO-42, and larger frame motors. We use Class F insulation wire, follow EMG original turn count and wire gauge specifications, and test all rewinds on our 3-phase motor test stand with thermal cycling before shipment. Rewind warranty is 12 months.
Do you stock original EMG spare parts?+
We maintain inventory of EMG stepper drive power MOSFETs, servo amplifier op-amps and voltage regulators, motion control module microcontrollers, and encoder interface signal conditioning ICs. For other components, we source directly from authorized EMG distributors in Germany with 5-7 day lead time. We never use substitute or counterfeit parts.
What documentation do I receive after EMG equipment repair?+
All EMG repairs include: detailed fault diagnosis report, component-level repair notes, test certificates with oscilloscope waveforms, and 12-month parts and labor warranty. For servo drives, we provide PI loop tuning records and closed-loop stability graphs. Digital reports are emailed; physical reports shipped with equipment.
How do I send my EMG unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a EMG drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on EMG repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your EMG unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
