A test method for motors under normal temperature and high pressure environment

Abstract

The invention discloses a test method for a motor under a normal temperature and high pressure environment. It belongs to the technical field of motor characteristic testing under normal temperature and high pressure environment. Its method steps are: put the motor under test and the accompanying motor into a high-voltage sealed barrel; the motor under test works in the motor state, and the accompanying motor works in the generator state; the stator current of the motor under test gradually changes from 1.5 times the rated current to 0.5 times the rated current; the stray loss PMs of the tested motor working in the motor state; the tested motor works in the generator state, and the accompanying motor works in the motor state; the stator current of the accompanying motor gradually changes from 1.5 times to 0.5 times the rated current; The stray loss PGs of the tested motor working in the generator state; combine the above measurement parameters and calculation results to obtain the average value of the load stray loss of the tested motor. The invention can detect the parameters of the motor in a high-voltage environment, and the stress acts on the whole motor, so that the stress direction of the motor is more diverse, and has a very wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of motor characteristic testing under normal temperature and high pressure environment. Background technique [0002] With the continuous increase of human demand for resources and energy, and there are extremely rich resources and energy needed by human beings in the ocean, the exploration of ocean resources is inseparable from motors as executive and functional components. , the pressure on the motor is also gradually increasing, so whether the motor can work normally under high-voltage conditions has become a key factor restricting the exploration and collection of deep-sea resources. Before the motor is used in deep-sea exploration, it should be accurately tested in the high-voltage environment where it may work Evaluation is crucial, and accurate testing also provides relevant basis for motor optimization. In view of the fact that most of the existing motor test methods are suitable for normal temperat...
