Two VFDs in a supermarket application. Bastien Piano Basics For The Young Beginner Pdf Writer there. 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 compressors in refrigeration applications today. Air and water can also be controlled more closely with motor speed controls. Because of this, many manufacturers of motors are working with electronic manufacturers and designers to pair up motors and electronic devices in order to efficiently and economically control the speed of a motor for capacity control. This article will cover a device the industry is using for three-phase motor speed and capacity control called a variable-frequency drive (VFD). Cities Xl 2012 Activation Key. The speed, or revolutions per minute (RPM), of a single-phase and three-phase alternating current motor is governed by the frequency of the voltage coming in the motor and number of poles of the motor.
