# Your question: What is a 4 pole motor?

Contents

## What’s the difference between a 2 pole and 4 pole motor?

A 2 pole motor has high speed due to less number of poles. Conversely, a 4 pole motor has low speed due to more number of poles. A 2 pole motor is more efficient on the flip side, a 4 poles motor is less efficient. A 2 pole motor has more RPM value; on the other side, the 4 poles motor has fewer revolutions per minute.

## What does 4 pole switch mean?

Four-way switches are used to control lighting from three or more locations. … There are four terminals that provide two sets of toggle positions on a four-way switch. Each set of terminals is one of the toggle positions. When the switch is in the up position, the current can flow through two terminals.

## How can we increase the RPM of motor?

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.

## What is a 10 pole motor?

A: A 10-pole motor would have 5-pairs of N-S poles. It would rotate at 50/5 = 10 rotations per second or 600 rpm (10 s-1 x 60 s/minute).

## How many coils does a 6 pole motor have?

To create a six pole motor use six coils per phase that creates three north poles and three south poles and so on. The number of stator slots is always a multiple of six.

## 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 happens if 60Hz motor is driven at 50Hz?

It will run with following problems for a 50Hz motor running on 60Hz: The core loss will increase and cause over heating of core. As the core loss will increase, the Power Factor of motor will reduce. The motor speed will be higher, so shaft load will increase.
