PURPOSE:To effectively control the speed of an induction motor by enabling to follow up a PLL circuit when the variation in the set frequency is higher than the varying width of the frequency of the PLL circuit. CONSTITUTION:The data of control speed of an induction motor is loaded from an...
Speed Control Method of a DC Shunt Motor What is Speed Control of an Induction Motor?Show More In this blog, we will discuss what speed control is, and the relationship between motors and speed control. By the end of this blog, you will be able to figure out the different speed contro...
Inthe multiple stator winding method of speed control, the stator is provided with two separate windings which are wound for two different number of poles. One stator winding is excited at a time. For example, suppose that a motor has two stator windings for 4 and 8 poles. For 60 Hz supp...
