The sensorless control of permanent magnet synchronous motors (PMSMs) is critical for reducing system complexity and improving reliability. By eliminating mechanical position sensors, drive systems ...

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 ...

Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, low-cost digital-signal controllers (DSCs) let designers use ...

AC motors are electric motors which are powered by alternating current (AC). They are used to convert electrical energy into mechanical energy in order to do work in a system. Specifically, rotational ...

$5M Bengaluru team patents EV motor that needs zero expensive magnets Bengaluru-based Vimag Labs has secured its fifth patent in India for “A Robust Rotating Transformer Excited Synchronous Motor and ...

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.

Find a downloadable version of this story in pdf format at the end of the story. Motors are used in countless consumer electronics applications, and technology improvements that have led to more ...

AC motor drives are defined as amplifiers or frequency inverters that interface between a controller and an AC motor. They convert step and direction input from the controller to currents and voltages ...
