Compressor motor part service life testing device and method

The invention discloses a compressor motor part service life testing device and method. The device comprises a test box, a top cover installed on the test box, a test cavity formed between the top cover and the test box, a motor part arranged in the test box, a refrigerant pipeline which extends into the top cover, a heating device and a power source; a motor part comprises a test rotor and a teststator; and the test stator is electrically connected with the power source. According to the compressor motor part service life testing device and method of the invention, the actual working condition of the motor of a compressor are simulated, so that the service life test of the motor can be carried out; the main parts of the motor, namely, the rotor and stator operate under a certain temperature and refrigerant pressure for preset time, so that the service life test can be completed. The compressor motor part service life testing device has the advantages of small occupied space, low power consumption and low cos
