You asked: Is a 2 pole motor faster than a 4 pole motor?

Why is 4 pole slower than 2 poles?

Motor Wiring and Number of Poles

A two-pole motor completes a full revolution with one polarity change, while a four-pole motor only rotates 180° with one polarity switch. More poles result in a lower motor speed: if all other factors are equal, a 4-pole motor will rotate at half the speed of a 2-pole motor.

Which is better 2 pole or 4 pole generator?

A 2-pole generator is often used because this avoids the need for a gearbox, but in many cases a 4-pole generator with gearbox would have a lower investment cost and provide a better utilization factor. For systems running at 3600 rpm, 2-pole generators are the favored option because gearboxes are not needed.

How do you increase motor speed?

Increasing the speed can be achieved by increasing the supply frequency as the speed and frequency are directly proportional; however, there are two constraints. The first is the saturation of the magnetic circuit, but this issue can be significantly avoided by keeping the V/f ratio constant.

Can a 60Hz motor run on 50Hz?

For a generic answer: yes you can, IF: you reduce the voltage by 50/60, the equipment doesn’t care, you don’t care about potentially overheating the motor, the process/load can tolerate the lower speed/torque, etc.

What is rated speed of motor?

The rated speed is the speed at which the motor will first produce its maximum designed power output, and “maximum speed,” the fastest the motor can spin while producing that same amount of power./:m] ]The reduction ratio should be applied on the RPM while your load is attached to the motor.

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.
