# Is a 2 pole motor 3 phase?

Contents

On a three-phase motor the pole pattern has to be repeated for each phase. Therefore a 2=pole, 3-phase motor will have six poles.

## What is a 2 pole motor?

A 2 pole motor is a type of motor that has two magnetic poles or a pair of magnetic pole, with a north-south configuration. A 2 pole motor consumes less energy, has more revolutions per minute, good noise performance and less work output.

## What is the difference between 2 pole and 3 pole motor?

Besides a few exceptions, you can see the difference quite easily by looking at the plug itself: 2-pole devices plugs have 2 pins and 3-pole plugs have 3. The exception, as previously mentioned, is the Schuko plug, which is normally used throughout Europe.

## What is pole in 3 phase motor?

When selecting a three phase motor, the number of poles is chosen to achieve the speed of rotation that you require. Here are two tables, one for a 50 Hz power supply and one for a 60 Hz power supply: The formula is n = 60 x f /p where n = synchronous speed; f = supply frequency & p = pairs of poles per phase.

## Is there a 3 pole motor?

Electricity-3-pole DC electric motor. A DC motor generates a rotating force via attraction and repulsion of magnetic fields. The magnetic fields in a three pole DC motor are generated by three electromagnets and two permanent magnets, as shown on the right. … This force is known as torque.

## How many RPM is a 2 pole motor?

A two-pole motor operates at 3,600 rpm (7,200 rpm Ã· 2) unloaded, and approximately 3,450 under load. Two-pole motors often are found in pump applications, such as sump pumps, swimming pool pumps, and water recirculating equipment.

## What is a 2 pole 3 phase motor?

The windings generate alternating N (north) and S (south) poles. As a result AC motors are 2-pole, 4-pole, 6-pole, etc. … On a three-phase motor the pole pattern has to be repeated for each phase. Therefore a 2=pole, 3-phase motor will have six poles.

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

The main difference between 2 Pole Motors and 4 Pole Motors is that 2 Pole Motors have a single pair of magnetic poles whereas 4 Pole Motors have two pairs of magnetic poles.

## Is 3 pole the same as 3 phase?

The three-pole breaker operates via the same method as a single-pole breaker. … Used most often in a three-phase electrical system, a three-pole breaker connects three different conductors, such as is often required by heavy duty industrial motors.

## What is a 4 pole 3 phase motor?

. For example, for a four-pole, three-phase motor, = 4 and = 1,500 RPM (for = 50 Hz) and 1,800 RPM (for. = 60 Hz) synchronous speed. The number of magnetic poles, , is equal to the number of coil groups per phase.

## What is the rpm of a 6 pole motor?

Using this equation, a 4-pole motor at 60Hz has a speed of 1,800 rpm, while a 6-pole motor at 50Hz has a speed of 1,000 rpm. However, this is actually the speed of the magnetic field, called the synchronous speed, which is not always equal to the shaft speed.

## What is 120 in motor speed formula?

The equation for calculating synchronous speed is: S = 120 f/P speed = constant (120) times frequency of power source (60 Hz) divided by number of poles used in the motor (P).

## How many total poles are there in a 4 pole three phase motor?

Thus each winding has four poles, i.e. the motor is referred to as a four-pole machine. Figure 4 shows that when the windings are connected to a three-phase supply, the magnetic field rotates at half the frequency of the supply. So for a 60 Hz supply, the field rotation speed is 30 rev/sec, i.e. 1800 r.p.m.

## Can a motor have an odd number of poles?

Motor have armature and field okay. … Uniform distribution of field is not possible with the odd number of poles which is necessary for the operation of a motor or a generator. So even no of poles is must in motors either AC or DC .

## What is a 6 pole motor?

6 poles = 1,000 RPM (~970 RPM) 8 poles = 750 RPM (~720 RPM) For a 60 Hz three phase supply: 2 poles = 3,600 RPM (nameplate would list around 3,500 RPM) 4 poles = 1,800 RPM (~1,740 RPM)

## What is a 5 pole motor?

There are in fact three separate coils (on a three-pole motor) or five separate coils (on a five-pole motor). When you turn your controller on, power is distributed to the sections of the coiled wire creating an electromagnet.
