Conduction angle control device of buried BDDC motor

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an interior permanent magnet (IPM) BLDC motor, in which an advance angle when driving a phase of a stator is set and controlled using a reluctance during a two-The present invention relates to a conduction angle control device for a buried type BLDC motor for increasing a total torque by lengthening a conduction section of each phase of a stator.;Conventionally, since the motor is controlled by setting the phase angle to be constant, the interval of the current flowing in the drive signal output section is shortened, so that the magnetic torque can not be used as the maximum. Therefore, Fall off.;In order to solve the above problems, in the present invention, the conduction angle is varied to extend the conduction period of the BLDC motor to maximize the magnitude of the torque generated by maximizing the magnetic torque and the magneto-resistance torque So that the efficiency of the motor can be improved.
