# How do you tell if a motor is 2 pole or 4 pole?

Contents

A two pole single phase induction motor has 4 windings, and a two pole three phase motor has 6 windings. But if you are looking at DC motors that may be totally different.

## How do you tell the difference between a 2 pole and 4 pole motor?

Key Differences

A 2 pole motor shows north-south configuration; on the other hand, a 4 pole motor shows north-south-north-south configuration. 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.

## What phase is a 4 pole motor?

The 3-phase 4-pole (per phase) synchronous motor will rotate at 1800 rpm with 60 Hz power or 1500 rpm with 50 Hz power.

## 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.

## What is the pole in motor?

The pole count of a motor is the number of permanent magnetic poles, north and south, on the rotor. There is always the same number of north and south poles on the rotor. For example, in a 12 pole motor, there are 6 north poles and 6 south poles. This motor would also be considered a 6 pole-pair motor.

## 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.

## How do I lower the RPM on my electric motor?

A couple of things you can do:

1. Use gears to change ratio of speed, which is what you’re going to do. …
2. Use a stepper motor, which are commonly used for high-torque, low RPM applications.
3. Find some sort of PWM control circuit to slow it down, although you probably won’t be able to get it down to 5-10RPM.

## 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.
