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 else can I help you with?
Is a 4 pole frameless motor brushless?
Yes, a 4-pole frameless motor is typically brushless. Frameless motors are designed without a traditional frame, allowing for a more compact and lightweight construction, and they utilize electronic commutation instead of brushes to switch the current in the windings. The 4-pole configuration refers to the arrangement of the magnetic poles in the rotor, contributing to the motor's efficiency and performance.
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 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
What pole motor is standard?
2, 4 or 6 poles
What is the synchronous speed of a four-pole motor connected to 50Hz?
The synchronous speed of a motor can be calculated using the formula: ( \text{Synchronous Speed} (N_s) = \frac{120 \times f}{P} ), where ( f ) is the frequency in hertz and ( P ) is the number of poles. For a four-pole motor connected to a 50Hz supply, the synchronous speed is ( N_s = \frac{120 \times 50}{4} = 1500 ) RPM. Thus, the synchronous speed of the motor is 1500 revolutions per minute.
What are the types of motor using in table fan?
The motor used in a table fan is usually a shaded pole motor.
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.
How to Reverse the direction of a stepper motor?
Suppose if u r using four pole stepper motor. keep the first coil on then energize second coil. and then again energise the first coil instead third coil. you will get reversed now.. all the best
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.
Is a 4 pole frameless motor brushless?

Frameless motors are designed without a traditional frame, allowing for a more compact and lightweight construction, and they utilize electronic commutation instead of brushes to switch the current in the windings.

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.
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 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
What kind of motor uses a differential reluctance pole to produce starting torque?
shaded pole
