Abstract

The present invention discloses a motor rotor temperature monitoring device, which can relatively accurately obtain temperature signals at different positions of a motor rotor, and can also form a power supply through a first power control circuit and a second power control circuit to supply power to a first temperature sensing module. Therefore, the first temperature sensing module can provide power to a plurality of temperature sensors installed at different positions of the motor rotor through continuously obtained electric energy, so that each temperature sensor can continuously monitor the temperature signals at different positions of the motor rotor, and finally obtain the temperature signal of the motor rotor that changes continuously during rotation. In addition, in the process of the power supply supplying power to the first temperature sensing module, the device will not be affected by the rotation of the motor rotor, so that the device has a long service life and a high service life, and can also reduce maintenance costs.
