Technical Field

[0001] The utility model relates to the technical field of brushless motors, in particular to a brushless motor control component and a brushless motor. Background Art

[0002] The brushless DC motor consists of a motor body and a driver. It is a typical mechatronics product. Since the brushless DC motor operates in an automatic control mode, it does not require an additional starting winding on the rotor like a synchronous motor that starts under heavy load under variable frequency speed regulation. It also does not produce oscillation and loss of step when the load changes suddenly. The permanent magnets of small and medium-capacity brushless DC motors now mostly use rare earth neodymium iron boron materials with high magnetic energy levels.

[0003] Existing technologies, such as the CN216216269U brushless motor and brushless motor frequency conversion processor, install a wire collection component on the motor body, cooperate with the rotating rod, the first scroll spring, and the limit assembly in the wire collection component, and at the same time cooperate with the slide groove and the slider on the casing and the fixed assembly set in the slider, so that after the frequency conversion processor adjusts its position, the length of the group line for connecting the Hall sensor and the length of the line for connecting the motor body are always adapted to the frequency conversion processor.

[0004] However, the device still has certain shortcomings during use. Since the casing of the device is integrally formed, the temperature inside the casing cannot be understood when the casing needs to be inspected or disassembled and installed. At the same time, when the motor speed is abnormal, it cannot be discovered in time, which reduces work efficiency. Since the motor generates a lot of heat when working, it needs to be cooled.
