How many RPM is a 8 pole motor?

What is the rpm of a 10 pole motor?

Synchronous rotation speed at different frequencies and number of poles

Shaft rotation speed – n – (rev/min, rpm)
Frequency – f – (Hz) Number of poles – p –
10 600 120
20 1200 240
30 1800 360

What is the difference between 4 pole and 8 pole motor?

Answers and Replies

On a 60 hz system a 2 pole motor runs at 3600 RPM minus slip. 4 pole would be half of this speed, 8 pole a quarter, etc.

What is an 8 pole motor?

First of all think of a DC Motor. If it is an 8-pole motor is will have 8 field coils evenly spaced all the way around it. Now, in an AC Motor with 3-phases you will have the 8-poles 3 times. That means you would have 24-groups of coils.

What is the synchronous speed of a 50 Hz eight pole motor?

For 50 Hz motors, the speed is 3,000 rpm with 2 poles, and 1,500 rpm with 4 poles.

What is the synchronous speed ns of a 3phase induction motor with 8 poles working at 50 Hz?

A three phase, 50 Hz induction motor has a full load speed of 1440 rpm. Speed of the stator field revolving rotor structure is? Explanation: Speed of the stator field revolving rotor structure = 1550-1440 = 60 rpm = 6.28 rad/s. 8.
