NettetSpeed Control of Induction Motor. To operate efficiently an induction motor must run with a small slip. It follows that any efficient method of speed control must be based on varying the synchronous speed of the field, rather than the slip. The two factors that determine the speed of the field, are the supply frequency and the pole number. NettetInduction motors are the most widely used motors for appliances, industrial control, and automation; hence, they are often called the workhorse of the motion indus-try. They …
