| Abstract: | In order to verify the rationality of the controlling algorithms, the controlling strategies and the motor parameters, a simulation model of the controlling system for the brushless DC motor controlled by a triangle-wave PWM is constructed based on the simulation platform of Matlab/simulink. The sub-modules of the controlling system are then introduced in detail. Moreover, according to the basic flux linkage equations of brushless DC motor, the operating mode of the three-phase square-wave motor with wye-connected phase windings and two mosfets is analyzed. The simulated results indicate that the proposed torque, and possesses quick simulation pace. model has a good response to the rotation speed and rotation |
