When the coil in the relay needs to run off an AC signal rather than DC. The shaded pole keeps the relay from "chattering" every time the AC current crosses 0v on the sine wave.

A shaded pole motor coil will have a resistance of approximately?
15 to 40 ohms.
What are some characteristics for a shaded pole motor?
The rotor is made up of laminated steel discs that are pressed on to a common shaft. This shaft has bearings mounted on either end which allows the rotor to spin within the frame of the motor. The shorting bars on the rotor are usually made of aluminium.
What would be the result of using a shaded pole motor for a high starting torque application?
disappointment. that is why most hand tools use dc motors
Are the motor used in tape recorder are split phase?
AC motors are not suitable for tape recorders because the speed can not be kept sufficiently constant. Tape recorders use dc shunt-wound motors with electronic speed control.
2 pole motor vs 4 pole motor?
A 2-pole motor has about 1.5 ft-lbs of torque per horsepower where a 4-pole motor has 3 ft-lbs of torque. also the speed of a 2-pole motor is twice that of a 4-pole motor. The speed of a motor is determined by: speed=(120 x freq)/no. of poles At 60 Hz, a 4-pole motor is about 1800 rpm where a 2-pole motor is 3600
How many poles can a shaded pole motor have?
2
What kind of motor uses a differential reluctance pole to produce starting torque?
shaded pole
What are the types of motor using in table fan?
The motor used in a table fan is usually a shaded pole motor.
A shaded pole motor coil will have a resistance of approximately?
15 to 40 ohms.
Why does a shaded-pole motor run at a constant seed?
The frequency of the applied voltage is consant.
Why does a shaded pole motor run at constant speed?
The frequency of the applied voltage is constant.
What will happen if you place too many washers on the end of a shaded-pole motor shaft?
The rotor will jam.
What if a shaded -pole motor is chattering or buzzing while it is turning the problem is most likely caused by?
A faulty or worn bearing.
What are some characteristics for a shaded pole motor?

What motor does a food mixer use?
Most likely the motor will be a shaded pole induction motor. If the food mixer has a place for brushed on the side of the motor and are oppositely opposed to each other, then it would be a universal motor.
How can a shaded-pole motor be reversed?
Yes, the rotation of a shaded pole motor can be reversed. It is advisable to only attempt this on a small motor and if you have general mechanical and electrical knowledge. The simple and direct explanation is one has to flip the stator. To do this the motor must be disassembled to a point at which the rotor can be removed. Once removed, turn it end over end and reinstall. Done. Note that the bearing housing ends will likely have to be switched as well.
