Gearmotor Breakdown Repairs & Electrical Fault Finding

Oil-seal leaks fouling motor windings, internal gear binding causing thermal overloads, and integrated brake slip disrupt critical mechanical power transmission. Lectro Power Systems delivers precision electrical testing, motor brake overhauls, and gearmotor replacements across Perth and regional Western Australia.
Symptoms We Resolve

Common Gearmotor Faults We Diagnose & Fix

  • Integrated Motor Brake Slip & Lockups

    Rectifying burnt DC brake coils, damaged bridge rectifiers, and incorrect mechanical air-gap tolerances.
  • Oil Ingress in Terminal Enclosures

    Cleaning oil-fouled terminal blocks, replacing degraded lead insulation, and fitting oil-resistant sealing gaskets.
  • Thermal Overload & Stalling Under Load

    Diagnosing mechanical gearbox binding, damaged gear teeth, phase loss, and undersized starter protection.
  • Torque-Arm Deflection Switch Trips

    Testing and wiring mechanical torque-limiting shut-off switches that protect driven shafts from over-torque.
  • Vibration & High-Temperature Bearing Trips

    Measuring internal winding thermistors, RTD temperature sensors, and motor bearing vibration levels.
  • Direct-On-Line & VSD Inverter Faults

    Resolving drive parameter mismatch, low-speed motor cooling fan failures, and voltage drop issues.
