A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.

Electric motors consume almost half of the electricity produced worldwide. They, in fact, provide the necessary driving force for much of today’s equipment. Motors, pumps, and fans are present in an ...

Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...

Selection of replacement motors is usually straightforward if the ratings are equivalent. Sometimes, however, a different type of motor is necessary or desirable. For success in these cases, it is ...

Motors are machines that convert electrical energy into mechanical energy using magnetic forces. When current is passed through a wire loop that lies in a magnetic field, a turning force, or torque, ...

The basic operating principles of SynRM machines. The advantages SynRM machines offer over switched reluctance motors. How the latest advances in SynRM design are steadily improving the motors’ ...
