LINEAR CONTROL METHOD OF BLDC

摘要

In the linear control method of the BRDCM(Brussless DC Motor) using a permanent magnet as a field magnet, the method comprises the steps of: setting a generation formula at a torque when a real current follows a current instruction; setting the functional formula for making completely the linearity of the generating torque; minimizing the power which is consumed to the heat at the linear control and the wired line resistor of a fixed stick; generating the maximum torque while the motor controls completely the linear control and restricts the current; and guaranteeing the current efficiency by minimizing the differential value according to the time of the current instruction.
