CMD Product Lines We Repair
Our engineers are trained on the full CMD product range. Below are the major product families we service.
CMD Stepper Motors (NEMA 17, 23, 34)
High-torque hybrid stepper motors used in CNC routing, embroidery machines, and indexing tables. Common repair issues include phase winding open circuits, missing step errors due to encoder misalignment, and coil insulation breakdown under thermal cycling.
CMD Servo Motor & Encoder Systems
Brushless DC servo motors with integrated optical encoders for closed-loop feedback. Failures include encoder sensor degradation, commutation phase errors, bearing wear causing position drift, and brushless controller desynchronization.
CMD Stepper Driver Boards
Microstepping driver boards for NEMA motors featuring current limiting and thermal management. Repair needs include MOSFETs short-circuit failure, decoupling capacitor aging, phase detection faults, and firmware corruption on newer PWM versions.
CMD Servo Amplifiers & Controllers
Single-axis and multi-axis servo amplifiers for position and velocity control. Common failures: power stage thermal runaway, encoder signal loss, loop stability oscillation, and analog input circuit failure under industrial noise.
CMD Gearboxes & Transmission Units
Planetary and harmonic reducers paired with CMD motors for torque multiplication in precision indexing applications. Issues include bearing preload loss, backlash creep, and coupling misalignment causing encoder read errors.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common CMD Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CMD equipment arriving at our workshop.
- ✓CMD stepper motor no rotation or stuttering — Phase winding short circuit, phase bridge failure in driver board, or misaligned motor coupling causing encoder step loss. Thermal stress in NEMA 23/34 motors often damages coil insulation.
- ✓CMD servo encoder signal loss or jitter — Optical encoder sensor contamination, loose encoder disk on motor shaft, or damaged encoder cable shielding from vibration. Industrial moisture ingress causes LED degradation in older CMD units.
- ✓CMD stepper driver overheating and thermal shutdown — Aged electrolytic capacitors in power supply stage reduce current capability, forcing MOSFETs to dissipate excess heat. Poor PCB thermal coupling or blocked heatsink fins exacerbates the issue.
- ✓CMD servo amplifier oscillation or unstable loop gain — Feedback loop gain tuning drift, encoder signal reflection noise on feedback cable, or internal compensation capacitor aging. Command signal filter desaturation also causes instability.
- ✓CMD motor position drift or cumulative counting error — Missing step pulses due to driver current limiting failure, encoder skipped counts from mechanical slippage, or firmware miscalibration in stepper control boards. Temperature-dependent coil resistance changes affect microstepping accuracy.
- ✓CMD brushless servo cogging or torque ripple increase — Commutation phase offset misalignment, Hall effect sensor angular displacement, or bearing drag from wear causing smooth rotation loss. Magnet flux degradation in older motors also causes cogging.

Frequently Asked Questions — CMD Repairs
Do you repair CMD equipment anywhere in India?+
Yes. Synchronics repairs the complete CMD motor and drive portfolio — stepper motors, servo systems, driver boards, and amplifiers. We offer PAN India door pickup from Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other major cities. All repairs are performed at our ISO 9001 facility in Vadodara, Gujarat, with 15-20 day turnaround.
What is typical repair cost for a CMD NEMA 23 stepper motor?+
CMD stepper repair costs depend on fault severity: phase winding replacement (INR 2,500-5,000), encoder recalibration (INR 1,000-2,000), or bearing replacement (INR 3,000-6,000). Synchronics provides free diagnosis and quotation within 24 hours. Many Indian textile and packaging OEMs negotiate annual maintenance contracts for volume discounts.
Do you stock genuine CMD replacement parts in India?+
Synchronics maintains inventory of critical CMD replacement components including phase coil assemblies, optical encoders, stepper driver MOSFETs, servo amplifier power stages, and bearing sets. We also source authentic parts through direct distributor channels for non-stock items within 3-5 business days across India.
Can you repair CMD servo amplifiers with burnt power stages?+
Yes. Our technicians remove and replace CMD servo amplifier MOSFET bridges, rectifier stages, and control ICs to factory specifications. We test rebuilt amplifiers under full-load conditions with precision power analyzer equipment. Synchronics also re-tunes servo loop parameters on repaired amplifiers — critical for Indian manufacturing environments with high vibration and electrical noise.
What warranty do you offer on CMD motor and drive repairs?+
Synchronics provides 12-month parts and labour warranty on all CMD repairs. High-wear components like bearings and encoders are warrantied for 6 months. We offer extended 24-month warranties for packaged systems and OEM contract repairs. All repairs come with detailed test reports and calibration certificates for quality assurance documentation.
How do I send my CMD 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 CMD 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 CMD 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 CMD 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.
