Variable frequency drives, or VFDs, are a type of AC motor controller that drive an electric motor by varying the frequency and voltage supplied to it. VFDs are also commonly known as variable speed or adjustable speed drives, AC drives, micro-drives or inverters – depending on the industry or application.
In the material handling industry, variable frequency drive controls are often used in electric hoists as well as in overhead cranes and lifting systems. Drives are designed around a microprocessor, which allows for the creation of programmable functions for specific applications.
Magnetek VFDs are designed for crane and hoist applications with various performance and safety features. A few of these features include:
This online course includes discussions of basic principles and operation of Magnetek’s industry-leading IMPULSE® AC variable frequency drives for crane applications.
