Motor vibration and noise performance experiment table, control method and application

Abstract

The invention belongs to the technical field of rotating motors, and discloses a motor vibration and noise performance experiment table, a control method and application. The experiment table comprises a voltage regulator, a frequency converter, a display, a tension controller, a torque rotating speed tester, a power supply, a magnetic powder clutch and the like. The voltage regulator is connected with the frequency converter through a line; the frequency converter is connected with the motor through a line; the motor is connected with the torque rotating speed tester through a coupler, and the torque rotating speed tester is connected to a display through a circuit; the torque rotating speed tester is connected with the magnetic powder clutch through the coupler, and the magnetic powder clutch is connected into the tension controller through a circuit. The temperature sensor, the noise sensor, the vibration sensor and the display are respectively connected to the test computer. The torque, the rotating speed, the power, the temperature, the noise and the vibration when the motor is in different operation states and carries different loads are measured into a whole, so that the stability of the motor in the operation process is judged, and the device has the advantages of compact structure, high universality and the like.

Description

technical field [0001] The invention belongs to the technical field of rotating electrical machines, and in particular relates to a motor vibration and noise performance test bench, a control method and an application. Background technique [0002] At present: With the development of the economy, environmental problems are becoming more and more prominent, and the use of coal and oil as power sources is also improving day by day, and the use of cleaner power facilities has also received more and more attention. Permanent magnet synchronous motor is more and more popular because of its advantages of high efficiency, low loss, small size and light weight. With the continuous research of people, the permanent magnet synchronous motor has been continuously applied to aviation, navigation and even the automobile industry, and its application is becoming more and more extensive. There are higher requirements for the stable operation of the motor and the reduction of vibration and...

Problems solved by technology

[0005] The existing motor performance test bench can only measure the data obtained in a single time, and cannot obtain the data at the same time

This has resulted in the inability to conduct an overall analysis of all parameter variables in the performance test, and the data measured at a single time are not in the same operating state of the motor, and the measured variables do not have timeliness with each other

Therefore, the existing motor performance test bench cannot provide complete data support for the design optimization and improvement of the motor
