Motorcycle batteries

A DC motor is designed to run on DC electric power.

• The brushed DC motor will generate torque directly from DC power applied to the motor leads, due to its internal commutation.
• Synchronous types, like the brushless DC motor and the stepper motor will lock up on DC power, and require external commutation to generate torque.
• Other types are purely DC and require no commutation.
  • the homopolar motor
  • the ball bearing motor
