Ac motor driver

Hitachi Japan Limited is our primary manufacturer for Variable Frequency AC Motor VFD Drives. Polypsede Electronics is our primary manufacturer for Variable Speed DC Motor Drives and Controls. Product gaps from our two major manufacturers are sourced from other manufacturers worldwide. (a.k.a. VFD, AC drive, inverter, variable speed drive, adjustable frequency drive) The basics: Variable frequency drives adjust your motor speed to closely match your output requirements, typically resulting in energy savings of 10 to 50%. AC drives change the speed of ac motor by changing voltage and frequency of the power supplied to the ac motor. In order to maintain proper power factor and reduce excessive heating of the motor, the name plate volts/hertz ratio must be maintained. This is the main Fundamental frequency: 60 Hz.

AC drives change the speed of ac motor by changing voltage and frequency of the power supplied to the ac motor. In order to maintain proper power factor and reduce excessive heating of the motor, the name plate volts/hertz ratio must be maintained. This is the main task of VFD. AC drives basic working principle. Thus, the AC input motor and driver system has superior torque characteristics over a wide speed range, from low to high speeds, offering a large speed ratio. It is recommended that AC input motor and driver systems, which are compatible over a wider range of operating conditions than DC input systems, be considered for your application. An AC Controller (Sometimes reffered to as a Driver) is known as the device that controls the speed of the AC Motor. An AC Controller can also be referred to as a variable frequency drive, adjustable speed drive, frequency converter, etc. The AC Motor receives power, which is ultimately converted by the AC Controller into an adjustable frequency.
