Abstract

The invention provides a motor rotor detection assembly and a motor. The motor rotor detection assembly (100) comprises a mounting bracket (1) and a sensor (4), wherein one end of the mounting bracketcan be fixedly mounted on a motor stator (2) while the other end can extend to one axial side of a motor rotor (3) in a position opposite to the motor rotor; and the sensor (4) is arranged at the other end of the mounting bracket (1) and can detect the position of the motor rotor (3). By virtue of the motor rotor detection assembly, the sensor can be mounted to the accurate position, the detection precision is greatly improved, the motor efficiency is improved, the condition that the motor cannot operate can be prevented effectively, and continuous and effective motor operation can be ensured; and detection can be performed by keeping the position of the sensor unchanged, so that influence to the rotor detection precision caused by movement of the sensor can be prevented, thereby effectively improving rotor position detection accuracy.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a motor rotor detection component and a motor. Background technique [0002] The existing current DC motors use Hall sensors to detect the rotor position in real time, and feed back the detected rotor position signal to the controller to realize the commutation of the motor, and generate a rotating magnetic field of the synchronous rotor in the stator. Therefore, the relative position of the Hall sensor and the rotor determines the best commutation position of the motor stator, and the best commutation position ensures that the stator current is synchronized with the electromotive force to achieve maximum torque output and optimal efficiency. [0003] However, in this way, the Hall position is installed during the production process. Due to the installation tolerance of the circuit board and the matching tolerance between the circuit board and the stator, the relative ...
