What are the stator of poles?
In an Induction motor synchronous speed is inversely proportion to No. of poles if we increase No. of poles speed will decrease they are derived through formula as under P= 120*f/Ns Where P= No. of Poles f= Rated frequency Ns= Synchronous speed of flux.
The speed of a synchronous motor with 60 Hz power supply is?
Speed (RPM) = 120 x f / p f = frequency p = number of poles. 2 poles, speed = 3600 RPM 4 poles, speed = 1800 RPM
How many poles are within a DC motor?
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.
What is the effect of increasing number of poles on the speed of an induction motor?
As the number of poles (P) increases, the speed of an induction motor (N) decreases. As seen by the formula: N=(120*f)/P
How 3 phase motors Speed is paired to number poles?
Directly propotional
Why the speed decreases when the poles increases in a motor?
because N=(120*f)/P where N= speed in rpm f= frequency in Hz P= no. of poles as the relations shows above it is cleare that speed of machine inversly proportional to no. of poles.. so as the poles increses, speed of the machine decreses

Single phase motor speed is determined by the?
Motor's number of poles.

What is the speed of the hp?
speed of the motor not depending the H P. It depends upon no: of poles in the stator and the supply frequency.
How 3 phase motors Speed is paired to number poles?
Directly propotional
What determines the output frequency of an ac generator?
It's speed and the number of poles.
How do you find the slip in induction motor?
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.
If A train travels at a constant rate of speed how long does it takes to get to the 15th poles it takes 10 mins from the first pole to the tenth poles poles are equal distance to each other?
Uhhh 5 minutes
What is the speed of 190 hp motor?
speed of the motor not depending the H P. It depends upon no: of poles in the stator and the supply frequency.
