Our in-house facilities are equipped with advanced diagnostic systems and testing equipment to support even the most complex repairs, ensuring your servo motor is restored to OEM specification—or better.

Comprehensive Servo Motor Repair Capabilities

We handle a wide variety of faults and failures that affect servo motors. From bearing noise and torque inconsistencies to feedback device issues and overheating, our engineers apply advanced diagnostics and precision tooling to deliver lasting repair solutions.

Common Issues We Repair:

  • Encoder or resolver misalignment

  • Feedback signal loss or noise

  • Bearing failure or shaft damage

  • Demagnetisation or torque inconsistencies

  • Contamination, overheating, or ingress damage

  • Electrical winding insulation breakdown

  • Noise, vibration, and general mechanical wear

Our structured, quality-controlled repair process ensures every servo motor is rebuilt to the highest standards of safety, reliability, and performance.

Servo Motor & Controller Repairs Under One Roof

Neutronic is one of the few UK companies capable of repairing both servo motors and their controllers in-house. This gives us—and our customers—a significant advantage:

  • We remove the guesswork between motor and drive issues.

  • We simulate real-world operating conditions during testing.

  • We load-test motors and drives together before returning them.

The result: faster turnaround, fewer delays, and guaranteed compatibility between repaired components.

Advanced Testing & Calibration

Our servo motor repairs are backed by industry-leading testing and alignment procedures, ensuring full restoration of performance.

Key Testing & Alignment Procedures:

  • Electrical Testing – Resistance, inductance, insulation, and surge testing

  • Mechanical Testing – Shaft runout, bearing inspection, and balancing

  • Feedback Calibration – Encoder, resolver, and tachometer alignment

  • Magnet Torque Testing – Restores original torque characteristics

  • Final System Test – Full load testing with dedicated servo drives
