Known for robust design and reliable performance in demanding industrial environments, AMCO equipment powers critical automation processes in hundreds of Indian factories.
Synchronics specializes in field repair of AMCO servo drives, stepper motor controllers, encoder interfaces, and motion control cards. Our 30-year track record includes restoring AMCO systems for Tier-1 automotive suppliers, textile mills, and precision equipment manufacturers across Gujarat, Maharashtra, Tamil Nadu, and Telangana. We diagnose commutation errors, phase faults, and encoder drift that cripple AMCO servo loops — restoring motion accuracy without replacement.
Expert AMCO servo drive and motion controller repair across India since 1994.
AMCO Product Lines We Repair
Our engineers are trained on the full AMCO product range. Below are the major product families we service.
AMCO SmartServo Drives
Closed-loop servo amplifiers for AMCO brushless and brush servo motors. Common failures include phase commutation loss, resolver signal dropout, and thermal shutdown under load cycling. Synchronics restores encoder feedback paths and commutation circuits.
AMCO StepperLogic Stepper Controllers
Microstepping driver boards for NEMA23, NEMA34, and NEMA42 stepper motors in CNC and packaging machinery. Failures include phase winding shorts, PWM timing drift, and encoder signal loss. Synchronics rebuilds driver stages and restores step/direction timing.
AMCO EncoderLink Interface Cards
SSI, CANopen, and Profibus encoder interface modules for multi-axis motion coordination. Common issues: resolver signal conditioning faults, CAN transceiver failures, and firmware corruption. Synchronics performs signal path analysis and firmware reload.
AMCO MotionSync Controllers
Real-time motion control PLCs with analog and PWM output for synchronized multi-axis drive systems. Failures include stuck outputs, analog DAC drift, and FPGA timing errors in high-speed machining. Synchronics restores output circuits and timing accuracy.
AMCO TorqueMax Brushless Servo Motors
Frameless and frame-mounted servo motors for machine tools, textile machinery, and robotics. Winding insulation breakdown, bearing preload loss, and hall effect sensor failure cause overheating and loss of commutation. Synchronics repairs motor windings, replaces bearings, and restores hall sensor circuits.
AMCO AutoSync Multi-Axis Coordinators
Distributed IO modules for synchronized control of multiple AMCO drives in printing, converting, and extrusion lines. Common failures: relay stiction, isolated DC supply failure, and input signal filtering loss. Synchronics restores switching logic and power delivery.

Common AMCO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AMCO equipment arriving at our workshop.
- ✓AMCO servo drive phase commutation loss — Encoder cable shield fracture or resolver signal conditioning capacitor failure in SmartServo drives causes invalid commutation feedback, tripping over-current protection. Heat cycling in dusty Indian textile mills accelerates connector corrosion.
- ✓AMCO stepper controller PWM timing drift — Crystal oscillator aging or decoupling capacitor ESR rise in StepperLogic boards causes step frequency to shift 2-5%, causing positioning errors in CNC axes. Vibration in machine tool environment accelerates oscillator drift.
- ✓AMCO encoder interface signal conditioning failure — ESD transient or supply voltage surge damages instrumentation amplifier input stages in EncoderLink cards, resulting in zero or saturated SSI/CANopen output across all axes. Indian industrial power quality issues trigger multiple surge events.
- ✓AMCO analog DAC output stuck or drifting — Reference voltage drift or DAC output amplifier biasing failure in MotionSync controllers causes axis to creep or lock at wrong position. High ambient temperature in un-air-conditioned machine shops accelerates drift.
- ✓AMCO brushless servo motor winding insulation breakdown — Thermal stress from continuous-duty operation or coolant contamination in machine tool spindle applications degrades phase insulation in TorqueMax motors. Voltage overshoot during PWM switching accelerates breakdown.
- ✓AMCO relay stiction in AutoSync distributed IO modules — Arcing and contact oxidation from switching high-capacitive loads causes relay contact resistance to rise or output to become intermittent in ASC modules. Vibration migration of relay armature worsens stiction.

What is the typical repair cost for an AMCO SmartServo drive?+
AMCO SmartServo repair costs range from 8,000 to 22,000 rupees depending on fault severity. Encoder signal path repair and component-level fix costs 8,000-12,000. Phase commutation circuit rebuild with full recalibration costs 15,000-22,000. We provide free diagnostic and written quote before any work begins.
Can Synchronics repair AMCO motors with insulation breakdown or bearing wear?+
Yes. Synchronics performs full winding rewind for AMCO TorqueMax brushless motors with insulation resistance below 100MΩ. We source Class H insulation wire and rebuild coils to original specifications using 4-axis winding machines. Bearing replacement includes preload setting and runout verification. Repaired motors come with 12-month warranty.
What is the lead time for AMCO stepper controller repair?+

What is the cost of repairing a AMCO 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 AMCO 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 AMCO 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.
