5 Causes of Motor Failure and How to Prevent Them

See our full range of electric motors here. 1. Electrical Overload. Electrical overload or over-current is caused by an excessive current flow within the motor windings, exceeding the design current which the motor is able to carry efficiently and safely. This can be caused by a low supply voltage, resulting in the motor drawing in more current in an attempt to maintain its torque. It can also ...
