GENERAL MOTION Product Lines We Repair
Our engineers are trained on the full GENERAL MOTION product range. Below are the major product families we service.
GM Brushless Servo Drives (BMD Series)
Compact servo amplifiers for brushless DC motors featuring integrated commutation logic and current feedback. Common failures include hall sensor interface faults, PWM output stage degradation, and firmware corruption leading to motor lock or uncontrolled acceleration.
GM Stepper Motor Controllers (SMC Series)
Microstepping driver modules for NEMA17 to NEMA34 steppers with step/direction or parallel port interfaces. Typical faults include phase winding shorts, logic input signal conditioning failures, and thermal shutdown events from insufficient heatsinking or blocked cooling vents.
GM Motion Interface Modules (MIM Series)
Real-time motion control processors with analog input conditioning, position feedback processing, and multi-axis coordination. Issues arise from analog opamp drift, stuck output relays, firmware boot failures, and timing synchronization errors in networked applications.
GM Encoder Interface Boards (EIB Series)
Quadrature and SSI encoder signal conditioning modules with software-selectable resolutions and velocity output. Repair focuses on differential signal amplifier faults, clock synchronization issues, and EEPROM configuration corruption affecting encoder scaling parameters.
GM Brushless Direct Drive Motors (BDDM Series)
High-torque, low-speed brushless motors with integrated hall sensors for direct-drive applications in packaging, textile, and robotics. Field failures include bearing preload loss, stator winding insulation breakdown, and integrated position sensor delamination under thermal cycling.

Common GENERAL MOTION Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GENERAL MOTION equipment arriving at our workshop.
- ✓Hall sensor signal loss or intermittent commutation — General Motion BMD series drives rely on three-phase hall sensors for commutation timing. Intermittent sensor contact, shorted signal wires, or failed hall ICs cause erratic motor phasing and thermal shutdown. Common in high-vibration textile and packaging environments where connector degradation accelerates.
- ✓PWM output stage failure or FET short circuit — Gate drive IC failures or bootstrap capacitor drying in General Motion BMD drives causes upper and lower FET pairs to conduct simultaneously, creating phase-to-phase shorts and catastrophic current surge. Occurs after 5-10 years in humid Indian industrial environments with poor electrical maintenance.
- ✓Stepper SMC phase winding short or open circuit — General Motion SMC stepper drivers experience stator phase winding faults from mechanical stress during tooling changes or thermal cycling in injection molding applications. Winding insulation cracks allow phase-to-phase shorts, causing driver IC thermal shutdown and loss of motor control.
- ✓Firmware boot failure or configuration corruption — General Motion MIM and EIB modules store motion parameters in on-board EEPROM. Power surges, flash memory wear, or improper firmware updates can corrupt startup code, leaving devices unable to initialize or accept network commands. Common after mains transients or UPS switching failures.
- ✓Analog signal conditioning drift or offset error — General Motion MIM and servo drive feedback circuits rely on precision op-amps for analog signal processing. Aging, temperature drift, or component stress causes DC offset accumulation, leading to positioning errors and servo loop instability. Manifests as creeping speed errors in long production runs.
- ✓Encoder interface signal synchronization or SSI protocol errors — General Motion EIB encoder boards process SSI or quadrature signals from rotary encoders. Clock timing errors, ground-loop noise, or firmware bugs cause position data corruption and loss of velocity feedback. Results in jerky motion or position overshoots in closed-loop applications.

Frequently Asked Questions — GENERAL MOTION Repairs
Do you repair General Motion equipment anywhere in India?+
Yes. Synchronics repairs the full General Motion product range — brushless servo drives, stepper controllers, motion interface modules, and encoder boards. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other major industrial cities. All repairs completed at our 180+ engineer facility in Vadodara, Gujarat with 7-14 day turnaround.
What is a General Motion hall sensor fault and how do you diagnose it?+
Hall sensor faults occur when the three commutation sensors in a General Motion brushless motor or BMD drive lose signal continuity, causing erratic phase switching and motor stalling. Synchronics uses specialized sensor test jigs to verify hall IC output levels, signal timing, and connector resistance. We also perform motor simulation testing to confirm commutation sequence under load before releasing the drive.
Can Synchronics repair General Motion stepper motors or only the SMC controllers?+
Synchronics repairs both stepper controllers and the motors themselves. For General Motion SMC stepper drivers, we replace burnt FETs, gate drivers, and microcontroller ICs. For stepper motors with winding shorts or open phases, we test insulation resistance and recommend motor replacement or field rewinding through partner shops. We coordinate full motor-controller system diagnostics to prevent controller re-damage.
How long does a General Motion drive repair typically take?+
General Motion servo and stepper drive repairs typically take 5-7 business days from receipt at Synchronics. Turnaround includes fault diagnosis, component-level repair or replacement, firmware reprogramming, full functional testing, and quality control. Urgent cases can be expedited to 2-3 days for critical production lines; contact our technical team to arrange priority handling.
Do you stock General Motion spare parts or program firmware updates?+
Synchronics maintains stock of critical General Motion components including power FETs, gate driver ICs, hall sensor amplifiers, and op-amp modules. We program all firmware updates, EEPROM configurations, and PID tuning parameters specific to customer applications. We also provide technical documentation and calibration certificates with every repair for traceability in regulated industries like pharmaceuticals and medical devices.
How do I send my GENERAL MOTION 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 GENERAL MOTION 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 GENERAL MOTION 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 GENERAL MOTION 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.
