Description

Technical Field

[0001] The utility model relates to the field of drive plates, in particular to an outer rotor drive plate. Background Art

[0002] An external rotor is a type of motor structure in which the rotor (the component that generates the magnetic field and rotates) is located on the outside of the motor, while the stator (the fixed component used to generate the magnetic field and interact with the rotor) is located on the inside of the motor. Compared with the traditional internal rotor motor (the rotor rotates inside the stator), this is a relatively special structural layout.

[0003] The outer rotor drive board is a circuit board used to control the operation of the outer rotor motor. The main function of the outer rotor drive board is to convert the input power signal into a suitable electrical signal to accurately drive the outer rotor motor to work according to the set requirements, such as controlling the motor's speed and direction. In the field of industrial automation, the outer rotor drive board can accurately control the operation of the outer rotor motor.

[0004] However, when the existing drive plate is used, it is not conducive to electromagnetic shielding of the outer rotor drive plate. The outer rotor drive plate has a weak anti-interference ability and is easily affected by external electromagnetic interference, which affects the stable operation of the outer rotor drive plate and is not conducive to the use of the outer rotor drive plate.

[0005] Therefore, we propose an outer rotor drive plate. Utility Model Content
