Applications of single phase squirrel cage induction motor
The present disclosure relates to the field of motors, and more particularly to a single phase induction motor and a washing machine having the same. The existing single phase induction motor for a pulsator washing machine is a four-pole motor and has a synchronous speed of rpm a power frequency of 50 Hz or rpm a power frequency of 60 Hz. The working principle of this washing machine is that the speed of the four-pole motor is reduced down to about to rpm by a primary reduction member to drive a container to rotate under a dehydrating condition, and to about to rpm by the primary reduction member and a secondary reduction member to drive the container to rotate under a washing condition. The existing pulsator washing machine has the following shortcomings in the specific application: the motor for driving the container to rotate is the four-pole motor with a relatively low synchronous speed of rpm the power frequency of 50 Hz or rpm the power frequency of 60 Hz , which results in a larger output torque under the same output power and a larger motor volume as the motor volume is directly proportional to the output torque, such that the space occupied by the motor in the washing machine is relatively large, thereby hindering the optimization design of the internal spatial structure of the washing machine. For overcoming the shortcomings in the related art, embodiments of the present disclosure provide a single phase induction motor and a washing machine having the same, which solves the problem that the space occupied by the existing single phase induction motor in the washing machine is relatively large. To achieve the above purpose, in embodiments of the present disclosure, there is provided a single phase induction motor for a washing machine, including: a stator and a rotor rotationally fitted with the stator, the stator includes a stator core and a stator winding disposed on the stator core, the rotor is of a squirrel cage type structure, and the single phase induction motor has two poles, a synchronous speed of rpm a power frequency of 50 Hz or rpm a power frequency of 60 Hz and a rated speed ranging from rpm to rpm the power frequency of 50 Hz or ranging from rpm to rpm the power frequency of 60 Hz.
