Description

technical field [0001] The invention relates to the field of automatic testing and measurement, in particular to a brushless motor testing device and testing method. Background technique [0002] In brushless motor control applications, it is of great significance to obtain the position information of the brushless motor rotor. At present, two methods are usually used to obtain the position information of the brushless motor rotor. One is to install a Hall sensor corresponding to the number of motor stator windings inside the motor, and the other is to use the back EMF signal generated on the stator winding when the motor rotor rotates. In the process of motor production, due to the guarantee of the production process, such as the change of the installation angle and distance of the Hall sensor, the change of the magnetization intensity of the motor rotor, and the parameter difference of the Hall sensor itself, etc., the obtained brushless motor often The position informati...
