Variable Frequency Drives

Hoists Direct offers many different types and sizes of variable frequency drives used in overhead crane systems.  Variable frequency drives are also commonly known as VFDs, adjustable speed drives or AC drives. Variable frequency drives are a type of AC motor controller that drive an electric motor by varying the frequency and voltage allowing for precise speed, energy efficiency and digital diagnostics.  Our hoist and crane VFD offering includes full load amperage (FLA) from 1.2 FLA to 1090 FLA and horsepower from 1/2 HP to 900 HP.  The VFDs that we offer can be installed in a 230 volt or 460 volt AC environment.  AC regenerative drive options and DC voltage drive options are also available.  We also can custom engineer specialty crane drives for unique applications, as well as provide on-site diagnostic services of hoist and crane drives in select markets.
