Waterproof Brushless Servo Motor is a motor designed to work in wet or underwater environments. These motors offer the efficiency, precision and programmability of brushless servo motors while being waterproof and moisture-proof to suit a variety of applications requiring water tightness. APISQUEEN mainly develops water and underwater equipment, and many customers have demands for waterproof servo motors. Under these needs, APISQUEEN has customized and developed waterproof servo motors for many customers, of which M400 is one of many cases.Features and application fields of waterproof brushless servo motor:Waterproof Design: The motor has a special seal and housing design to protect the...

The choice between an inner rotor and an outer rotor brushless motor depends on the specific requirements of the application. Inner rotor motors are favored for their compact size and rapid response, while outer rotor motors excel in providing high torque and continuous operation. 

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...
