How single-phase induction motor classified?
The single phase induction motors are made self starting by providing an additional flux by some additional means. Now depending upon these additional means the single phase induction motors are classified as: 1.Split phase induction motor. 2.Capacitor start inductor motor. 3.Capacitor start capacitor run induction motor. 4. Shaded pole induction motor.
What will happen if you place too many washers on the end of a shaded-pole motor shaft?
The rotor will jam.
What are the advantages and disadvantages of using a shaded pole motor?
Advantages, Disadvantages and ApplicationsThe various advantages of Shaded pole motors includes Very cheap and reliableEasy to constructExtremely rugged in natureDisadvantages includesLow efficiencyLow starting torqueSince the shading coil is made of copper, the copper loss is high.See the related link for further information.
Why pole changing method of speed control of three phase induction motor can not be used?
because its possible only where pole changing arrangements are given and pole changed motor draws more current then its actual pole which damages its windings.
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.
What are the applications of a shaded pole motor?
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.

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 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.
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.
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.
Ac relay and DC relay?
what is the meaning of ac relay and dc relay EDIT: a DC relay is simply a coil and core that pulls on an armature. An AC relay usually needs a shaded-pole core (couple of copper loops) to prevent the armature from vibrating at 60 cycles or so. The core, also, is laminated steel like a transformer; so is the armature to help contain the magnetic field. You should not substitute a DC rated relay for an AC , but the reverse should be ok, if voltage and current ratings are the same.
What will happen if you place too many washers on the end of a shaded-pole motor shaft?
The rotor will jam.
What are the types of motor using in table fan?
The motor used in a table fan is usually a shaded pole motor.
