Hitachi Variable Frequency Drives

Hitachi, Drives

We can divide all electric motor drives in two major categories: DC and AC. An electric motor drive regulates the torque, direction, horsepower and speed of a motor. A DC drive generally regulates a shunt-wound DC motor, which has independent field circuits and armature. AC motor drives regulate AC induction motor, and, like their DC prototype, they also regulate torque, horsepower and speed.

Hitachi produces a full range of AC VFI induction motor drives under 500hp. Thus, four leading production lines offer a great variety of apparatus in the commercial HVAC and industrial markets.

VFD saves energy by lowering the amount of power used by motors driving fans, centrifugal pumps and other different rotating-based equipment. The quantity of energy consumed by the machinery is balanced and optimized owing to motor speed control. Reduced energy converts into emissions of the reduced carbon (CO2). Hitachi is devoted to environmental protection, that is why this company tries to provide its customers with “green” equipment. Here is a short description of the six production lines of Hitachi VFDs.
