Title:
TEMPERATURE DETECTION APPARATUS AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2020/215780
Kind Code:
A1
Abstract:
A temperature detection apparatus and a motor, the apparatus being used for motor rotor surface temperature detection, and comprising temperature sensors (1) used for detecting the temperature of the surface of a rotor; fixing apparatus (2) which are mounted in stator grooves (4) of a motor stator (3) and which are used for fixing the temperature sensors (1) at positions facing the motor rotor. Under the premise of the temperature sensors not damaging the structures of the stator and rotor, the sensor arrangement means is simplified, which reduces the difficulties of implementation, simultaneously prevents the interference of strong electromagnets on signal transmission, and obtains a relatively accurate real-time temperature of the surface of the rotor; feedback is inputted to a controller, the output performance of the motor is thereby adjusted, further temperature increases are controlled, and the stability of the performance of the magnetic steel of the rotor of the motor near an operating point is ensured.
