Electric Motor Faults: Frequently Asked Questions

This section looks at the electric motor faults most often met in the field, starting from the symptom. Every answer follows the same pattern: a short diagnosis, the likely causes, then a check order carried out with the power isolated and by a qualified electrician. The aim is not to swap the faulty motor straight away but to find the cause, because a cause left in place will wear out the new motor in the same way. Current and speed examples in the answers are nameplate values of models in our catalogue.

If the motor has to be replaced, the buy electric motors section lists three-phase models from 0.25 to 355 kW by power and speed; motors ship from stock at our warehouse in İzmir/Buca. Send a photo of the faulty motor's nameplate and of its terminal box on WhatsApp and we will work out the equivalent model together.
