Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

Microprocessor control lets variable-speed PMSMs save energy. Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

NORD offers IE5+ motors in sizes 71, 90, and newly released, size 112, extending the power range from 0.5 to 15.0 hp.

Combining the advantages of permanent magnet and induction motors, new synchronous reluctance motors (SynRM) offer potentially breakthrough technology for variable speed drive (VSD) and motor packages ...

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 ...

Using variable frequency drives (VFDs) to control the speed of a compressor can provide improved occupant comfort and quieter operation in air conditioning and heat pump applications. Tight ...

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 ability to control the motors’ speed and rotation is the design key of drones, making the electronic speed control (ESC) module an added value and a fundamental part of a drone. In this article, ...
