The two most important electric motors are the ac induction motor and the permanent magnet (PM) brushless synchronous motor, also known as the brushless dc or ac servo motor. These motors have ...

The transmission for most vehicles can be configured according to the scheme presented here. Such a transmission may be primarily useful for electric or hybrid vehicles, but is quite applicable to ...

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.

The power of a synchronous motor depends directly on the load angle: the greater the load angle, the more torque, which determines the power by the speed specified by the input gear and the ...

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 ...

New and increasingly stringent efficiency standards have made motor efficiency a priority among motor manufacturers and designers of motor-driven systems. While the Energy Independence and Security ...

Other available options for permanent-magnet motors that use rare-earth materials. What is an EESM? Tula's DMD alternative to achieve EV powertrain efficiency. The scale of automotive electrification ...
