Hitachi Variable Frequency Drives

Hitachi manufactures a complete family of AC Variable Frequency Inverter induction motor drives below 500hp. Four major product families cover a wide array of applications in the industrial, process, and commercial HVAC markets.


Variable Speed Drives save energy by reducing power consumed by motors driving centrifugal pumps, fans and other rotating equipment. By controlling the speed of a motor, the amount of energy used by the machinery is optimized. Reduced energy use translates to reduced carbon (CO2) emissions.


Hitachi is committed to protecting our environment by providing you with products that help you reduce your environmental impact. Below is a description of the six product families of variable frequency drives offered by Hitachi.
