Motor & Drivetrain

Motor Performance Testing & Servicing

We service all EV motor types — BLDC, PMSM, induction, and switched reluctance — with dynamometer-based performance mapping that benchmarks real-world output against rated specifications. Early detection of efficiency loss, bearing wear, and insulation degradation keeps drivetrains running at peak.

• Torque-speed curve mapping and efficiency verification across motor types
• Winding insulation resistance testing and surge analysis
• Bearing vibration diagnostics with predictive replacement scheduling
• Rotor and stator condition assessment for all motor technologies

Drive Unit Repair & Maintenance

The integrated drive unit — motor, gearbox, and differential — determines how power reaches the wheels. We service the complete assembly to preserve mechanical efficiency and extend drivetrain life, from routine lubricant changes to full teardown and rebuild.

• Reduction gear inspection, shimming, and lubricant replacement
• Differential and half-shaft service for consistent power delivery
• Seal and gasket replacement to prevent fluid ingress and contamination
• NVH analysis to isolate and resolve noise, vibration, and harshness issues

Power Electronics

Inverters, DC-DC converters, and motor controllers manage the high-voltage power flow that drives performance. We diagnose and repair at the component level — IGBT modules, SiC devices, gate drivers, and capacitor banks — restoring full efficiency without unit replacement.

• Inverter fault diagnosis and IGBT/SiC power module replacement
• DC-DC converter output regulation testing and board-level repair
• Capacitor ESR testing and degraded bank replacement
• High-voltage connector and harness integrity verification

Cooling System Diagnostics

Motor and inverter cooling systems operate under sustained thermal loads that directly impact efficiency and component life. We ensure cooling infrastructure maintains optimal operating temperatures across all duty cycles and climate conditions worldwide.

• Coolant flow rate measurement and pressure drop analysis
• Radiator and heat exchanger cleaning, testing, and restoration
• Electric water pump and thermostat valve performance verification
• Thermal interface material reapplication on power module mounts

Control Unit Programming & Calibration

Motor control units, vehicle control units, and auxiliary controllers define drivetrain behavior across every operating condition. We program, recalibrate, and validate these systems to preserve the performance and efficiency characteristics each platform was engineered to deliver.

• Motor controller parameter mapping and torque table optimization
• Regenerative braking profile calibration for efficiency and driver feel
• VCU fault code analysis, clearing, and logic validation
• Firmware update staging with rollback capability
