Feedback form is now closed.
Electromagnetic excitation is the main source of vibration and noise of asynchronous motor, but the electromagnetic excitation force can not be measured directly, it can only be verified indirectly. In this paper, a 7.5kW asynchronous motor of Y2-132M-4 is taken as an example. Hall sensors are arranged on the inner surface of the stator to measure the magnetic induction intensity by a unique test device, comparing the calculated results with the experimental value,and accuracy of the experiment method is verified. The study provided necessary measures for quantitative analysis of electromagnetic excitation force.
