Abstract

Objective The speed fluctuation of the Holzer sensor of Brushless DC motor is often compared with the speed fluctuation. which often can not be used as the feedback signal of controller. In this paper ,we try to resolve this problem. Methods The method of frequency multiplication is improved, and a new method is adopted to measure the speed of the motor. Results we propose a solution to this problem,the problem of the instability of the original velocity measurement method is improved, which can solve the problem of velocity fluctuation. Conclusion:A new method of frequency multiplication is proposed. The control precision was 0.25% and 1% respectively. The method is proved to be feasible and effective. The module can be used as the speed feedback device of the brushless DC motor controller, and the other speed device is not required. It can be used in the speed field of ordinary brushless DC motor.
