Abstract

An integrated motor temperature and angle sensor disclosed by the invention comprises a shell, an angle sensor, a temperature sensor, a PCB and a connection wire harness, the shell is provided with a through hole, the shell is provided with a first installation part and a second installation part, the first installation part and the second installation part are arranged at an interval, the second installation part is located at the outer side of the first installation part, a gap capable of accommodating a magnetic ring of a motor rotor is formed between the first installation part and the second installation part, the angle sensor and the PCB are arranged on the first installation part, the angle sensor is connected with the PCB, the temperature sensor is arranged on the second installation part, and the connection wire harness is connected with the PCB and the temperature sensor. The integrated motor temperature and angle sensor has the beneficial effects that the detection precision is high, the overall size of the motor is reduced, and the installation space occupied by the motor is saved.

Description

technical field [0001] The invention relates to the field of motors, in particular to an integrated motor temperature and angle sensor. Background technique [0002] Generally, the motor is equipped with an angle sensor and a temperature sensor. The angle sensor is used to detect the motor rotor speed to determine the motor speed. The temperature sensor is used to detect the temperature of the stator phase line to monitor the temperature inside the motor body in real time to prevent overheating and burning. . However, the traditional temperature sensor is installed inside the magnetic ring, the detection coil temperature is blocked by the magnetic ring, and the detection accuracy is low. In addition, the traditional temperature sensor and angle sensor are directly connected to the inverter through connecting terminals, and the inverter must be assembled with the motor body, so that the installation positions of the motor body and the inverter are limited, and the requiremen...
