To reap all the benefits that an electric motor drive can offer, choose one that's a perfect match for your application A speed control enables the motor to achieve maximum efficiency during all ...

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 ...

Choosing the right motor and VFD type depends on a variety of factors; however, it is necessary to analyze how the motor changes when the speed is reduced. The experts at eMotors Direct outline ...

Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

Since AC induction motors have been established as the preferred choice for industrial motors and the need for reduced power in all aspects of design is ever present, the efficiency of these motors is ...

For the PDF version of this article, click here. More than 80% of the motors bought each year continue to be low-cost single-phase ac motors. Because these motors are not very efficient when ...

This document written by Steve Bowling, Application Segments Engineer at Microchip Technology, discusses how motor works and describes the AC induction motor, variable-speed ACIM control, and FOC.

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.
