Kelly Controller - how to tell how many poles you have??

How do I tell how many poles my brushless hub motor has?

Is it a crystalyte ? or other ?

ananda

control chart shows 2 north and 2 south -- whether that is what it means by poles is my guess...

there are 2 magnetic poles

there are 3 electromagnetic poles.

Which one the controller is referencing, Not sure. Ask the manufacturer?

On a brushless motor, the number of stator poles will be a multiple of 3. The number of rotor poles (magnets) must be a multiple of 2. The number of stator poles will typically not be the same as the number of rotor poles. My BMC motor has 18 stator poles and 16 rotor poles. I don't know what an Ananda has.

You can take apart the motor and count the poles if you really want to know. You could measure the output of one of the hall sensors to determine the number of rotor poles (count the number of voltage toggles during one motor revolution).

Fortunately, this does not usually matter much. This is usually only an issue if you get up to very high rpm, where the controller may not be able to keep up.

I have a Kelly controller that came preconfigured for a Puma....it was set to 150 poles!
