Circuit Globe Induction Motor Shaded Pole Induction Motor Shaded Pole Induction Motor A Shaded Pole Induction Motor is a simple type of starting single phase induction motor. It consists of a starter and a cage-type rotor. The stator is made of salient poles. A copper ring is fitted on the smaller part of each pole. This section of the pole is known as Shaded Pole. The ring is usually a single turn coil and is known as Shading Coil.
The connection diagram of the Shaded Pole Motor is shown single.de app geht nicht. An alternating flux is produced in the field core when the alternating current is bildkontakte coins to the field winding. A portion of this flux links with the shading coil which behaves as a short circuit secondary of the transformer. Voltage is induced in the coil and, as a result, current circulates dating on whatsapp india the circuit.
The induced flux is single stammtisch trier by the current which is induced in the motor, and it opposes the main shaded pole type single phase induction motor flux. The flux generated in the shaded portion is produced by the single mann uber 30 coil is represented by a as shown in the above figure to lag behind the flux in the unshaded portion b of the pole. As there is a time and space displacement between the two fluxes, the conditions for setting up a rotating magnetic field is produced.
This rotating flux develops the starting torque in the rotor. The direction of the rotation of the flux is in a clockwise direction, i. In this motor, the reversal of the direction of rotation is not possible. Shaded Pole pole motors are very cheap, and starting torque developed by the motor is also very low. The losses are high, and the power factor of the motor is low. Hence, the efficiency of the motor is very low.
Because of all these reasons, the shaded pole motors are built of the small size of the rating of 40 W singleborse burgenland less. Applications of the Shaded Pole Motor This type of motor is used to drive the devices which require low starting torque. The various applications of the Shaded Poles Motor are as follows: Used in exhaust fans, hair dryers and also in table fans.
Used in la bleu chat conditioning and refrigeration equipment and cooling fans. Record players, tape recorders, projectors, photocopying machines. Used for starting electronic clocks and single phase synchronous timing motors.

For example, a motor with high locked-rotor and breakdown torques can damage the equipment it drives. The general characteristics of these types of single-phase induction motors are as follows. Note that pull-up torque is a factor in single-phase motors to ensure starting with high-inertia or hard-to-start loads. As its name indicates stator is a stationary part of induction motor. In order to reduce the hysteresis losses, stamping are made up of silicon steel. The solid-state switch will be the switch of the future as it is refined and costs are reduced. The current distribution within the rotor bars varies depending on the frequency of the induced current. We know that for highly resistive winding the current is almost in phase with the voltage and for highly inductive winding the current lag behind the voltage by large angle. Advantages and Applications No centrifugal switch is needed. In Depth Tutorials and Information SINGLE-PHASE INDUCTION MOTORS Electric Motor 1. However, resistor losses associated with low speed operation of WRIMs is a major cost disadvantage, especially for constant loads. So, these motors produce very high starting torque.
