![]() There is no physical connection between the stator and rotor, but there is a small and uniform gap between them. These rotor bars are permanently shorted at both ends with the help of end rings as shown in figure. The rotor consists of uninsulated aluminum or copper bars which are placed in the slots. The rotor is a rotating part and its construction is of squirrel cage type. This winding is excited with a single phase AC supply. These stampings consists of slots on its periphery to carry the stator winding. The stator is a stationary part and it has laminated construction, which is made up of stampings. The construction of these motors is more or less similar to a three-phase squirrel-cage induction motor. ![]() Single phase induction motors consist of two main parts stator and rotor. These motors are also called as fractional KW motors, because most of these motors are constructed in fractional kilo-watt capacity. These are small in size and less expensive to manufacture. Single phase induction motors are extensively used in low power applications such as domestic appliances as mentioned above. Introduction to Single Phase Induction MotorsĪs the name suggests, these motors operate on single phase AC supply.
