MUNICH, Germany—ZF unveiled an electric motor that does not require magnets or rare earth materials, reducing reliance on mining in countries such as China and cutting manufacturing's carbon footprint ...

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.

An introduction to the symmetric, multiphase, wound-rotor “synchronous” doubly-fed motor or generator system, called SYNCHRO-SYM. How SYNCHRO-SYM is only possible with brushless, automatic, ...

The Dodge HT500 synchronous drive system offers high torque and low maintenance with less overhung load than V-belt drives. The HT500 belts offer longer life in wet/oily environments than their rubber ...

This advanced variant of a separately excited synchronous motor is thus an alternative to permanent-magnet synchronous machines (PSM). New Delhi: ZF has developed an electric motor which does not ...
