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
What is the advantage by using 8 pole motor instead of 6 pole motor?
The number of poles in a motor will determine the speed of that motor. n=speed, f=frequency, p=# of poles. n=(120f)/p So a 6 pole motor is rated to operate at n=(120*60)/6=1200 rpm. assuming 60Hz frequency Or a 8 pole motor is rated to operate at 900 rpm. Of course due to slip the rotor will always spin slightly slower.
What pole motor is standard?
2, 4 or 6 poles
Developed diagram of 3 phase 2 pole 24 slots induction motor?

A shaded pole motor coil will have a resistance of approximately?
15 to 40 ohms.
Is the tekin SC4X motor a 4 pole motor?
it is a 20 pole motor
What are the benefits of a three-pole motor over a two-pole motor?
A 3-pole motor has a smother torque curve.
What is differene between 2 pole 4 pole electric motor?
A 2-Pole motor runs twice as fast as a 4-pole motor. The 2-pole motor has 2 windings at 180 degrees apart and the four pole motor has four windings at 90 degrees apart. The rotor tries to move from pole to pole with each half cycle of the AC current so the motor no-load speed for 60 cycle current is 2x3600/#poles. This is 1800 rpm for a 4-cycle motor and 3600 rpm for a 2-pole motor.

Which motor used in refrigerator?
shadded pole motor
Why motor need pole?
electric and magnetic go hand in hand. One needed to produce other. Motor no magnetic pole, motor no work.
What is pole pitch?
Suppose we have a N-pole electrical machine, then the angular distance between the consecutive poles when expressed in degrees is POLE PITCH. eg. for a two pole machine (one north and one south pole), the pole pitch is 180 degrees, and for a 4-pole machine: it is 90 degrees. Note that this is so when expressed in Mechanical degrees, whereas in Electrical degrees it is always 180 degrees. Therefore: POLE PITCH (mechanical)=180/(n/2): n=no pf poles.
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.
What kind of motor uses a differential reluctance pole to produce starting torque?
shaded pole
What is the relationship between motor POLE and RPM?
Relationship between motor rpm and no of poles
