Problems solved by technology

[0002] With the increasing requirements of social energy efficiency upgrades, brushless DC motors have high energy efficiency and are widely used. In order to ensure the reliability of motor startup and operation, a sensor solution is usually used. The motor controller of this solution needs to detect the position signal of the motor rotor (magnetic field) to Normal operation, so to check the functional integrity of the motor driver, it must be installed inside the motor before the test can be carried out, resulting in the failure of the controller production unit to realize the single board function test;
