BRADHARRISON Product Lines We Repair
Our engineers are trained on the full BRADHARRISON product range. Below are the major product families we service.
Bradharrison Stepper Motor Controllers
Microstepping drivers and position controllers for NEMA and IEC stepper motors. Common issues include encoder feedback loss, phase winding shorts, and inadequate torque output under load.
Bradharrison Brushless Servo Drives
Closed-loop brushless DC servo controllers with hall sensor and resolver feedback. Typical faults include commutation errors, thermal runaway, and loss of synchronization.
Bradharrison Motion Control Modules
Standalone and distributed motion controllers for multi-axis systems. Common problems include axis coupling failures, axis communication dropout, and real-time timing violations.
Bradharrison Encoder Interface Boards
Quadrature and SSI encoder conditioning cards for position feedback. Frequent issues are capacitive coupling noise, encoder cable damage, and signal conditioning drift.
Bradharrison Spindle Drive Systems
High-frequency spindle controllers for precision machining and grinding. Common faults include bearing temperature overshoot, spindle speed instability, and phase imbalance.

Common BRADHARRISON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BRADHARRISON equipment arriving at our workshop.
- ✓Bradharrison servo drive encoder feedback loss — Bradharrison drives rely on continuous hall sensor or resolver feedback for commutation. Connector oxidation, shielding degradation, or internal encoder module failure disrupts the feedback loop, causing the drive to fault with encoder loss error codes (typically E15 or E16 variants).
- ✓Bradharrison stepper motor phase winding open circuit — Thermal cycling, vibration, or manufacturing defect can break phase winding continuity in Bradharrison stepper motors. This results in loss of torque on one or more motor axes, visible as stalling or jerky motion during positioning.
- ✓Bradharrison motion controller axis synchronization failure — In multi-axis systems, Bradharrison MCM controllers synchronize slave axes to a master reference. Encoder scaling drift, real-time latency, or corrupted axis offset tables cause axes to diverge, triggering sync error codes and production stoppages.
- ✓Bradharrison spindle drive thermal runaway and speed instability — Spindle drives operate at high switching frequency and dissipate significant heat. Thermal sensor degradation, cooling fan failure, or PI loop tuning drift causes the drive to overshoot target speed or enter thermal shutdown prematurely.
- ✓Bradharrison drive firmware corruption or checksum mismatch — Power transients, software updates interrupted mid-flash, or hardware memory defects corrupt the flash memory or RAM checksums in Bradharrison drives. The drive fails to initialize or exhibits erratic behavior after power-up.
- ✓Bradharrison encoder connector and shielding degradation — Industrial environments with vibration and temperature swings degrade connector plating and shield effectiveness on Bradharrison encoder cables. This introduces noise into feedback signals, causing position jitter and sporadic control instability.

Frequently Asked Questions — BRADHARRISON Repairs
Do you repair Bradharrison equipment anywhere in India?+
Yes, absolutely. Synchronics repairs the full Bradharrison product portfolio — stepper motor controllers, brushless servo drives, motion control modules, encoder boards, and spindle drive systems. We offer pan-India pickup and delivery from all major cities: Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and beyond. All repairs are completed at our central facility in Vadodara, Gujarat, ensuring consistent quality and faster turnaround.
What is the typical repair time for a Bradharrison servo drive fault?+
Most Bradharrison servo drive faults are diagnosed and repaired within 5-7 working days. Simpler issues — such as connector reseating, firmware reload, or encoder cable replacement — may be completed in 2-3 days. Complex repairs involving component replacement or coil rewinding take longer. Synchronics provides daily status updates and expedited service for critical production shutdowns.
Can you repair Bradharrison stepper motor controllers with custom microstep configurations?+
Yes. Synchronics engineers are experienced with Bradharrison's proprietary microstep settings and motor pole configurations. If your stepper controller is programmed for a specific microstep resolution or current ramp profile, we preserve that configuration during repair and test the controller against your exact motor specifications before return. We also reprogram custom parameters if required.
Do you offer calibration and testing after Bradharrison motion drive repair?+
Yes, comprehensive post-repair testing is standard. For servo and spindle drives, we perform load-dependent performance validation, thermal stress testing, and speed stability verification. For stepper controllers, we test all phase currents and microstep positions. For motion control modules, we verify multi-axis synchronization and real-time timing. We provide a detailed test report and warranty coverage on all repairs.
What Bradharrison fault codes do you handle most frequently in Indian plants?+
Common codes we repair include E15/E16 (encoder feedback loss), E22 (motor phase open), E33 (thermal sensor fault), E41 (sync error on multi-axis systems), and E55 (firmware checksum mismatch). Synchronics maintains a comprehensive Bradharrison fault code database and can often diagnose root cause from error code history alone. Contact us with your fault code for a quick assessment.
How do I send my BRADHARRISON 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 BRADHARRISON 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 BRADHARRISON 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 BRADHARRISON 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.
