knoxie wrote:no that doesnt look like halls then, check the connections from the hall sensors to the controller, red and black should be 5V and the others should pulse when you power the wheel.

Basically, the DC comes in and gets switched by a bank of FETs. Hall effect sensors on the motor tell the controller when to switch so that the magnetic attraction is always in the same direction.
