SYNCHRONICS Equipment We Repair — By Category
SYNCHRONICS Product Lines We Repair
Our engineers are trained on the full SYNCHRONICS product range. Below are the major product families we service.
Synchronics Stepper Motors
2-phase and 3-phase stepper motors (NEMA23, NEMA34 frame sizes) used in precision positioning applications. Common faults include winding short circuits, bearing wear, and rotor magnet demagnetization from thermal stress or electromagnetic spike damage.
Synchronous Motor Drive Systems
AC synchronous motors paired with digital drive controllers for speed-locked applications. Typical failures: encoder signal loss, drive module capacitor degradation, and phase imbalance detection errors in 3-phase supply systems.
Servo Amplifier Modules
Compact servo drive modules for closed-loop motion control in multi-axis systems. Common repair issues: PWM IGBT failures, encoder interface faults, and firmware corruption due to power loss or lightning surge.
Motion Controller Cards
Programmable motion control cards with pulse/direction and analog velocity input interfaces. Failures typically occur in optoisolator circuits, crystal oscillator drift, and relay contact welding on output stages.
Feedback Encoders & Sensors
Incremental and absolute encoders designed for Synchronics motor shafts. Repair needs include cable insulation breakdown, slip ring carbon contact wear, and bearing play causing position jitter.
Brake & Load Cell Integration Modules
Spring-applied brake controllers and tension feedback modules for web handling and winding applications. Common faults: solenoid coil burnout, load cell signal conditioning failures, and relay hold-in voltage loss.

Common SYNCHRONICS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SYNCHRONICS equipment arriving at our workshop.
- ✓Stepper motor phase loss and cogging — Synchronics stepper motors fail when winding insulation breaks down due to thermal cycling in high-speed continuous-duty applications, or when the drive amplifier module loses output stage transistors. Cogging (jerky movement) results from encoder misalignment or phase imbalance in digital drive firmware.
- ✓Encoder signal dropout and jitter — Synchronics incremental encoders suffer from cable shield disconnection at motor connector, slip ring carbon dust accumulation, or bearing side play causing gap variation in optical path. Digital noise from VFD proximity causes false zero crossings in SSI/CANopen models.
- ✓Drive amplifier module capacitor swelling and leakage — Synchronics servo drive modules (SAM series) use 100uF/400V electrolytic capacitors that fail after 5-8 years in Indian industrial environments due to high ambient humidity and temperature cycling. Electrolyte dries out, ESR rises, and bulk supply voltage drops under load.
- ✓Synchronous motor speed drift and hunting — Synchronics SYN-series motors lose lock during startup or load surge if drive phase current ramps too fast, or if motor bearings have excessive friction from corrosion. Line voltage notching from nearby SCR/VFD circuits destabilizes phase-lock loop in digital controllers.
- ✓IGBT and diode failures in servo output stage — Synchronics SAM amplifier IGBTs (typically 600V/25A or 1200V/10A) fail due to gate drive capacitor ageing, paralleling device current imbalance, or transient overvoltage from motor back-EMF spikes when emergency-stop is engaged. Freewheeling diodes fail from reverse recovery stress.
- ✓Firmware corruption and motion controller lockup — Synchronics motion controller cards (MC/MCC series) suffer EEPROM corruption from power loss during parameter write cycles, or firmware checksum errors after software updates. Watchdog timer circuits fail, halting pulse output and leaving motors uncontrolled.

Frequently Asked Questions — SYNCHRONICS Repairs
Do you repair Synchronics equipment anywhere in India?+
Yes. Synchronics Electronics Pvt. Ltd. repairs the full Synchronics product range — stepper motors, synchronous motors, servo drive modules, motion controller cards, encoders, and brake controllers. We offer PAN-India door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, Kolkata, and all other metro cities. All repairs are done in our 5000+ sqft facility in Vadodara, Gujarat, with 25+ years expertise in Synchronics motion control systems.
How long does Synchronics motor or drive repair typically take?+
Standard Synchronics motor winding repair (rewinding, insulation test, phase balance) takes 3-5 working days. Servo drive module repairs (capacitor replacement, IGBT rebuild, firmware recovery) take 2-4 days. Encoder and motion controller repairs take 1-3 days. We offer express turnaround (24-48 hours) for critical production equipment. Emergency repairs in Vadodara can sometimes be completed same-day if parts are in stock.
What is the warranty on Synchronics repairs at Synchronics Electronics?+
All Synchronics motor, drive, and controller repairs carry a 12-month parts and labour warranty. Rewound stepper and synchronous motor coils are tested at 1.5x rated voltage for insulation integrity. Servo drive modules are load-tested for 8 hours before release. Firmware repairs include 2 years of free software updates. Warranty covers defects in workmanship and material replacement, excluding mechanical damage or incorrect installation.
Can you repair Synchronics stepper motors if the shaft is bent or bearing is seized?+
Yes. Synchronics stepper motors with bent shafts can be repaired by shaft realignment or replacement (we stock NEMA23 and NEMA34 shafts). Seized bearings are replaced with original SKF or FAG needle bearings during full motor rebuild. However, if the core lamination is damaged (visible cracking), the motor cost-benefit ratio typically favors replacement. Our engineers will advise after bearing load and run-out testing.
Do you repair Synchronics servo drives with CANopen or SSI encoder interfaces?+
Yes. Synchronics SAM servo amplifiers and motion controller cards with CANopen, SSI, and analog encoder inputs are regularly repaired. We service the optoisolator circuits, re-flash firmware with latest Synchronics stack, and re-test encoder signal conditioning on our calibrated test bench. Common SSI failures (slip ring wear, cable shielding loss) are repaired with component-level rework and validation against Synchronics protocol analysers.
How do I send my SYNCHRONICS 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 SYNCHRONICS 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 SYNCHRONICS 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 SYNCHRONICS 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.
