Read MoreThe actual grinding process of the ball mill cannot be measured due to the limited experimental conditions. So, the induction motor is used as the load. The no-load back EMF of the prototype is measured under an open circuit, as shown in Figure 42. The measured back EMF is 205.1 V, and the simulated back EMF is 211.3 V.
