Inventor: KWON YOUNG GI
IPC: H02P5/00
Filed: 1998-09-12
Abstract: PURPOSE: A device for controlling a motor and method thereof is provided to control a bias voltage so that a control voltage generating object frequency of a motor may be located in a central voltage of a control range by reflecting a load variation of a motor in the bias voltage. CONSTITUTION: A device for controlling a motor includes a memory(260), a bias setting portion(280), a speed error detector(230) and a controller(250). The device for controlling a motor controls the speed and phase of the motor within a control range determined by a set bias voltage after a speed error information detected and a phase error information are mixed. The memory stores the bias voltage(Bm) determining the control range of the motor, tolerant error(ferr) and object rotation frequency(fcm) of the motor by a corresponding mode. The bias setting portion determines the control range as a value corresponding to the bias voltage stored in the memory. The speed error detector calculates a difference of the object rotation frequency and a real rotation frequency of the motor. The controller compares the difference with the tolerant error. When the absolute value of the difference is larger than or equals the value of the tolerant error, the controller changes the bias voltage of the bias setting portion in proportion to the difference in order to move the control position of the motor into a center point of the control range.
