EV's are 24V. The EV Warrior charger I have is 24V. They can be run at 12V of course.
This motor was originally used in the EV Warrior electric bicycle. The company went bankrupt and thousands of the motors were sold as surplus. It is probably a custom version of the Bosch GPB automotive fan motor. There are two versions available, one with the timing advanced 10° in the clockwise (CW) direction and one with timing advanced 10° in the counter-clockwise (CCW) direction. One of the motor's terminals is grounded to the case and this grounding tab must be removed or you may short out your speed controller through the frame.
