BEST Product Lines We Repair
Our engineers are trained on the full BEST product range. Below are the major product families we service.
BEST Frequency Converters (AC Drives)
Three-phase variable frequency drives for motor speed control in textile mills, paper production, and sugar processing. Common repairs involve capacitor failures, IGBT module degradation, and control board faults affecting ramp-up and fault tripping.
BEST Soft Starters
Reduced-inrush motor starters for pump motors, compressors, and conveyor drives. Repair issues include thyristor firing circuit faults, cooling fan motor failures, and phase loss detection circuit breakdown in industrial environments.
BEST Servo Drive Systems
Closed-loop motion controllers for positioning, synchronization, and precision assembly. Common faults include encoder interface errors, analog signal conditioning circuit failures, and firmware corruption causing servo lock-out and position drift.
BEST Gearbox Control Modules
Integrated motor-gearbox electronic controls for agricultural equipment, food processing, and material handling. Typical repairs address cooling system blockages, slip ring contact wear, and control relay chattering.
BEST Encoder and Feedback Systems
Absolute and incremental position feedback modules for closed-loop industrial control. Repair scope includes connector corrosion, bearing wear causing signal dropout, and signal conditioning amplifier faults.

Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common BEST Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BEST equipment arriving at our workshop.
- ✓BEST drive capacitor bank short circuit — Electrolytic capacitors in the DC link degrade under sustained high ambient temperature and thermal cycling in Indian summer conditions. Moisture ingress through damaged conformal coating accelerates failure in coastal and humid regions.
- ✓BEST soft starter thyristor firing circuit failure — Gate drive opto-isolator degradation in humid industrial environments causes incomplete thyristor turn-on, leading to uneven phase current distribution and nuisance fault trips. Printed circuit board trace corrosion near power terminals accelerates the breakdown.
- ✓BEST servo drive encoder interface error — Connector pin corrosion, damaged encoder cable shielding, and bearing wear in the coupled encoder hub prevent clean digital signal transmission. Environmental dust and vibration in textile and sugar mills accelerate mechanical wear of encoder mounting.
- ✓BEST frequency converter IGBT module thermal runaway — Thermal paste degradation between IGBT and heatsink, combined with clogged cooling fins from mill dust and cotton fiber accumulation, creates thermal hotspots. Defective cooling fan bearings reduce air circulation, causing junction temperature to exceed safe limits.
- ✓BEST soft starter phase loss detection malfunction — Voltage sensing resistor network degradation or analog-to-digital converter failure prevents accurate input phase voltage monitoring. This can mask single-phase operation, leading to overheating and starter damage in unattended installations.
- ✓BEST gearbox control module cooling system blockage — Thermal interface fluid contamination from worn bearing seals and metal particulate accumulation restricts heat transfer. Conformal coating breakdown allows moisture and dust infiltration into cooling passages.

Frequently Asked Questions — BEST Repairs
Do you repair BEST equipment anywhere in India?+
Yes. Synchronics repairs the full BEST product range including frequency converters, soft starters, servo drives, and gearbox control modules. We offer PAN India door-to-door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other cities. Single repair facility in Vadodara, Gujarat ensures consistent quality and faster turnaround.
What is the typical repair turnaround time for a BEST frequency converter?+
Standard BEST drive repairs take 5-7 working days including diagnostics, component replacement, and full-load testing. Expedited service is available for critical production lines — we can prioritize your unit within 48 hours of receipt. Estimated timelines are provided after initial technical assessment.
Can you repair BEST drives with burnt IGBT modules or damaged power stages?+
Yes. Synchronics holds OEM-grade IGBT modules, rectifier bridges, and power stage assemblies for all major BEST converter families. We replace damaged power semiconductors, test gate drive circuits, and perform thermal cycling validation before return. Full schematic support enables us to repair even severely damaged boards that other shops cannot restore.
Do you provide warranty on BEST repair work?+
All repairs carry a 12-month parts and labor warranty covering manufacturing defects and component failures. We also offer extended warranty options and preventive maintenance contracts for plants running mission-critical BEST equipment. Warranty terms are detailed in our service agreement.
What documentation do you provide for BEST equipment repair?+
Each repaired BEST unit returns with detailed test reports including oscilloscope waveforms, thermal images, fault code logs, and before-after performance metrics. We include the original user manual, spare parts list, and maintenance schedule. Telemetry data is retained for 2 years to support future troubleshooting.
How do I send my BEST 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 BEST 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 BEST 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 BEST 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.
