The brushless motor/thruster cannot be connected directly to the power supply. The phase sequence is controlled by the controller (ESC) in order to ensure the motor/propeller operates properly and can make the motor/propeller work more efficiently. If you need to use a brushless motor, please make sure to pay attention to the correct operation method to ensure the normal use and long life of the motor.

Brushless motors require the use of Hall elements to detect the rotor position for proper phase change for proper motor operation. Usually two Hall elements are used to detect the rotor position. This is implemented as follows:1: Two Hall elements are mounted on the stator of the brushless motor at a certain offset angle relative to each other.2: When the rotor rotates close to the first Hall element, the element will detect the magnetic field and output a signal indicating that the rotor has turned to the corresponding position.3: Based on the received signal, the motor controller determines the current...
