Ac variable speed drive

Hitachi is a leading manufacturer of easily configurable and modular AC variable speed drives and industrial inverters. Our range of industrial AC drives and inverters is eco-friendly, which reduces power consumed by motors driving centrifugal pumps, fans and other rotating equipment. Hitachi industrial AC variable speed drives control the speed of a motor and optimize the . Variable-frequency AC motor drives do not require motor speed feedback the way variable-speed DC motor drives do. The reason for this is quite simple: the controlled variable in an AC drive is the frequency of power sent to the motor, and rotating-magnetic-field AC motors are frequency-controlled machines by their very nature. For example, a 4-pole AC induction motor . The basic function of a variable speed drive (VSD) is to control the flow of energy from the mains to the process. Variable speed drives sit between the electrical supply and the motor. Power from the electrical supply goes into a drive and the drive then regulates the power that is fed to the motor. Inside the drive the input power is run through a rectifier, that converts the incoming AC .
