pole mortor ms 225-40
Name plate data should indicate the number of poles / RPM. For speed N= (120 x Frequency) / Number of poles Using this formula you can find out the number of poles, provided you have other parameters available. If no data is available, run the motor on no load, and measure the rpm, know the frequency, calculate the poles.
The two main factors are the frequency and the number of poles of the motor. A formula for RPM is HZ x 60 x 2/ number of poles the motor has.
How do you calculate 3ph AC motor power?
how to calculate resistance box for slipring motors
because of the residual magnetic flux that exists in the motor initially due to the poles
To calculate the speed of an induction motor use the following formula, RPM = Hz x 60 x 2/motor # of poles. To answer the question, most of the motors must have 4 poles.

It depends on the motor. They can be purchased with different numbers of poles. The number of poles mainly changes the speed of the motor.
Motor's number of poles.
The poles of the electromagnet are repelled and attracted to the poles of the field magnet in the motor, causing it to spin a commutator or rotor in the motor. A brush flips the poles to keep the electromagnet spinning and the rotor moving.
how to calculate hydraulic motor torque
The two main factors are the frequency and the number of poles of the motor. A formula for RPM is HZ x 60 x 2/ number of poles the motor has.
calculate the synchronous speed from the frequency & the no. of magnetic poles in the stator, then measure the actual speed of it with a tachometer, then subtract the actual speed from the synchronous speed.
The part of an electric motor that repels the poles of the permanent magnets is the fly wheel.

how to calculate hydraulic motor torque
The formula for RPM is ; RPM = Hz x (120 (constant)) divided by the # of poles. Number of poles a motor has; # of poles = Hz x (120 (constant)) / RPM.
