A shaded pole AC motor has a part of it's stator short circuited by a copper ring. When the flux in the main part of the stator increases, the flux through the copper ring with have a small delay, since it wants to keep its flux constant. Therefor you get a small rotational component to the field distribution, which makes the rotor turn.

∙ 8y agoTwo things to check for. Make sure that the motors coil windings do not have an open in them, Check and make sure that the shaded pole windings do not have an open in them. Some shaded pole coils consist of a single solid turn of large wire wrapped around the end of a pole face. These can get damaged through rough handling. Stress cracks can form in the wire of the shaded pole coil which if open will prevent the motor from starting.
One other thing is to check the bearings. Usually the motor has bushing bearings, if they dry out the rotor will stop turning. The amperage will not go high enough to trip the breaker to open the supply voltage. A spin of the rotor will let you know if this is the trouble. Just oil the bearings and see if the motor will then run.

Which line runs vertically from north to south poles?
The lines of longitude run from pole to pole.
What two things do lines of longitude and landitude run?
Lines of latitude run round the earth parallel to the Equator. Lines of longitude run from pole to pole, crossing the Equator at 90 degrees.
What lines of a map run from north pole to the south pole?
lines of equal longitude, a.k.a. meridians
Do the longitudinal lines run parallel to the Equator?
No. Longitudinal lines run parallel to the Prime Meridian. Latitudinal lines run parallel to the Equator.
Do longitude lines run from pole to pole?
At the poles, the idea of longitude is essentially meaningless. Take a few steps either way; your longitude will depend on which way you walked. Of course, from the pole itself every direction is "South", which makes navigation a little challenging.....
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 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.
What type classification would a motor with copper bars in the rotor fall into?
although this is not a chemistry question I do have an answer for you. A motor with copper bars is classified as a shaded pole motor. They are low torque motors and do not require any capacitors for run or start functions. hope that helped
Can you bend baffels in exhaust with hammer and pole?
You would be sure to destroy them if using a hammer and pole, you would need to make sure they do not clog up the pipe as well otherwise your motor wont run well at all.
How do you differentiat dc motior and ac motor physicaly?
if you power an ac motor with dc or a dc motor with ac you will likely start smelling smoke and the motor will be damaged. If the motor is marked "3-phase", "shaded pole", or "induction" it is an ac motor! BTW, there are ac/dc motors that will run on both, they are wound very much like dc motors but a bit differently.
What would cause an electric motor to run backwards?
Motors running backwards: A DC motor wired backwards or magnetic field reversed. A 3 phase AC motor with 2 phases reversed A single phase motor will run either way unless it is 'persuaded' by means of a shaded pole or other method to rotate in a particular direction.
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.
Can a 22re motor fit in a 1985 Toyota pickup truck that came stock with a 22r motor?
Sure.. just pull the wiring harness to run the EFI. the carb motor harness wont run the efi.. yes it will. i did it in my truck
Can a 4 Pole 50 Hertz 440 V induction motor run at 900 rpm?
No. With the values given the motor will run at 1500 RPM. RPM = Hz x 60 x 2/# of poles. The only way the motor can be run at that speed is by using a VFD as its source of power.
How does a motor run?
the north pole magnet and straight rod present in the moter .the current flow in the rod and rod rotate on the magnetic force.And the moter run.
Why wont my Blower run on 1997 aurora?
Same problem on mine...I had the blower motor module replaced and it works great.
