We inspect the local isolator, cables, and terminal connections before touching any mechanical parts. ### Electrical testing and fault diagnosis Using calibrated test instruments, we measure insulation resistance between windings and to earth. We check continuity, winding resistance across phases, and inspect the condition of bearings, terminals, and starting capacitors. ### Motor replacement or component repair If the motor has burnt out, we disconnect the wiring, unbolt the frame, and install a matching replacement unit. On repairable faults, we replace worn terminal blocks, install new overloads, or replace failed starting components. ### Testing rotation and full load current Once reconnected, we re-energise the circuit, verify that the motor spins in the correct direction, and measure running current against the motor nameplate rating to confirm that the unit is not overloaded. ## Questions about motor repairs and installations ### What causes an electric motor to repeatedly trip the fuse board? A motor usually trips a circuit due to damaged winding insulation, an earth fault, a seized bearing creating locked rotor current, or an incorrectly rated protective device. We carry out insulation and resistance tests to determine whether the fault sits inside the motor or within the supply wiring. ### Do you work on both single phase and three phase motors in Wimborne Minster? Yes. We work on single phase motors fitted to domestic pumps, garage doors, and extract fans, as well as three phase motors powering commercial saws, compressors, hoists, and ventilation systems in workshops and industrial premises. ### Can a burnt out electric motor be repaired on site? External issues such as damaged terminals, failed start capacitors, burnt contactors, and loose connections can be repaired on site. If the internal copper windings have completely burnt out, we replace the motor with a new unit or arrange for external workshop rewinding. ### Will I receive an electrical certificate after a motor installation? When a new motor circuit is installed, or when notifiable alterations are made to your distribution board, we issue an electrical installation certificate through our NAPIT registration. Standard like for like component swaps include written test records. ### What information should I note down before booking a motor replacement? Taking a clear photograph or note of the motor nameplate is extremely helpful. The nameplate states the power rating in kilowatts or horsepower, operating voltage, full load current, frame size, speed in revolutions per minute, and mounting configuration. ## Other services in Wimborne Minster - [Electrician in Wimborne Minster](https://mx2-electrical-ltd.co.uk/electrician-wimborne-minster): Electrical testing, fault finding, repairs and planned installation work across Wimborne Minster, Leigh Road, Allenview and BH21. - [Electric motor installation and repair (all areas)](https://mx2-electrical-ltd.co.uk/services/three-phase-motor-installation-repair): MX2 Electrical installs and repairs single and three phase motors in Poole and Dorset.
