Shaded Pole Single Phase Induction Motor Diagram
Let s spend a few minutes comparing shaded pole psc and ec motors.
Shaded pole single phase induction motor diagram. They belong to the family of induction squirrel cage motors that are used in limited applications that require less than 3 4 horsepower usually ranging from 1 20 to 1 6 horsepower. The rotating magnetic field develops the starting torque in the motor. The connection diagram of the shaded pole motor is shown below. Read here to know about the shaded pole motors their constructional features working and how they are used in starting of single phase induction motors.
There are three types of single phase induction motors which are the shaded pole split phased and capacitor motors. They re usually single speed low horsepower motors used for things like light ventilation. Shaded pole motor wiring diagram the shaded pole motor is the original type of ac single phase induction motor dating back to at least as early as a shaded pole motor is a small. A shaded pole induction motor is a simple single phase induction motor which is self starting with one of the poles shaded by the copper ring.
Shaded pole motors as seen in figure 3 are single phase induction motors found operating small cooling fans inside refrigerators in computers. When single phase ac supply is given to the stator winding due to shading provided to the poles a rotating magnetic. A shaded pole electric motor is a single phase induction motor provided with an auxiliary short circuited winding or winding s displaced in magnetic position from the main winding. This trusty motor is your standard single phase ac induction motor.
As there is time and space displacement between the two fluxes the rotating magnetic field induces in the coil. This type does not have start winding so to start this motor use the means of the circuit. The other name of the copper ring is a shaded ring where it acts as a secondary winding motor. The shaded pole motor is the original type of ac single phase induction motor dating back to at least as early as 1890.
A continuous copper loop around small portion of each of motor poles is rounded by the means of this circuit. Shaded pole motor is one of the types of single phase induction motors which are used for producing a rotating stator flux in order to make the single phase induction motor a self starting one let us discuss the constructional details diagrams and working of shaded pole motors in detail. There s nothing terribly sophisticated about a shaded pole motor. There are a number of different construction methods used but the basic principle is the same.
A shaded pole motor is a small squirrel cage motor in which the auxiliary winding is composed of a copper ring or bar surrounding a portion of each pole.
