Application of Hall Effect in the Control of Brushless DC Motor

Hall Effect is a very important magnetoelectric effect,which is applied in the measurement of non-electrical quantities,automatic control,and information processing and so on.Based on the introduction of Hall Effect and the work principle of brushless DC motor,this article will give a detailed exposition on the application of these Hall sensors in the control of brushless DC motor.And the article also describes the basic characteristic and the conditions to be met of the Hall sensors used in brushless DC motor.In the end,the paper looks forward to the future application of Hall sensor and points out the Hall sensor will be used widely.
