Electric motor failures are often caused by “in-operation” factors, such as production activities and the factory environment in which they operate. Other failures are due to “off-line” factors, ...

As an electric motor’s rotor turns in close proximity to the motor windings, a bucking voltage or back electromotive force (EMF) is generated. The back EMF (BEMF) generated across the start winding is ...

Bearing failures are the most common cause of electric motor and generator failure. Maintenance professionals can optimize the life of these machines by following industry best practices for bearing ...

When you think of electric motors, you usually think of magnets. But magnets are heavy, and good magnets can pose problems when you need lots of them. A technology called SESM (separately excited ...
