Please correct me if I am wrong but i believe the number of poles in a motor refers to the stator windings or magnets as opposed to the number of wires. i.e. a 4 pole PMDC motor would have 2 sets of magnets and a corresponding 2 sets of brushes. The brushes would likely be wired together internally such that there would be only two wires to connect the coils to the motor controller. A 4 pole motor would be controlled in the same way a 2 pole motor would be. Whether or not the motor and motor controler mentioned above are compatible depends on the stall and operating current specs of the motor and controller.

@ superdroid, my apologies i apparently missed that the first time i read through your post.

it is also possible to register the falling and rising edges of both the A and B channel signals. this would allow you to get 4 registrations per each count of the encoder, i.e. a 10 PPR encoder could give you 40 registrations per revolution.
