## What is pole count?

Manufacturers define their pole count **by the number of pole pairs or stator windings**. Increasing the number of pole pairs on the rotor itself (or adding more stator phases) increases resolution. … Rotation step angle is half that of a permanent-magnet stepper motor with the same number of stator windings.

## 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 a 4 pole 3 phase motor?

With a 4-pole machine, the rotor will move from 1 pole pair to the next in 1 AC supply cycle, so will do half a rev in one supply cycle – the synchronous speed is therefore 50/2 revs per second, or 1500 rpm. A 4-pole induction motor will have a nominal speed of **1450** rpm or thereabouts.
