Frequency Drives

Frequency converters are used to drive motors used in spindles. In general, frequency converters are used to convert power for equipment used in applications where dissimilar voltages and frequencies are the norm. Frequency converters are an ideal source of power for entire factories. Typical applications of frequency converters include AC variable frequency drives, computers and computer controlled equipment, inverters, deep well pumps, industrial machinery, aircraft, ships, military computers, machine tools and many more. They are used for converting power frequency, voltage and phase in any industrial application.

 

What is a frequency converter?
A converter is an electronic device that converts alternating current (AC) of one frequency to alternating current of another frequency which at times may also change the voltage if it is required for the principal purpose.

 

Frequency converters in spindles
A frequency converter is very essential to provide power and speed to any type of spindle. It is a power control unit used providing motor speed in spindles. It is designed to drive motors that are used in high frequency spindles on grinding, milling, drilling machines, lathes and other machine tools. These units are able to operate and control three-phase induction motors or synchronous motors, AC, DC motors as well as brushless DC-Motors. The power range of the frequency converter differs depending upon the size and the application of the spindle.

 

Features of frequency converters
Almost all frequency converters used to run spindles have the following features:
