Three phase motor drive with constant V/F speed control and slip regulation
This paper deals with the design and analysis of a three phase induction motor drive maintaining a constant V/F ratio. An analysis of the steady state equivalent circuit model of an induction motor is presented to establish the equations that justify the use of a constant Volts/Hertz speed control. In order to compensate the voltage at low frequencies it is necessary to obtain the equivalent circuit model impedances by means of laboratory tests. A proportional-integral controller and a slip regulator were implemented in order to present a good speed response, and the motor consume a low current and present a good power factor. The paper also describes the design of the control stage and presents the results obtained from the motor operating at different frequencies.
