Bicycle DC brush hub motor



This motor consists of technology that has been around for over a century and is very simple in design. It has a positive wire going into the motor, and a negative wire coming out of it, and is driven by a single phase electrical pulse sent from a Controller. Inside the motor, mechanical brushes and a commutator (armature) switch the pulse of electricity back and forth to create a "push-pull" magnetic field in the coils, which are in the center of the motor. As a pulse of electricity is sent to the motor from the controller, the coils create a strong magnetic field, which repulses them from the magnets that surround the coils, and causes the motor to advance (rotate) away from the magnets - making the motor spin.. The only moving parts - parts that can wear out - in this motor are the brushes and the center bearing. The brushes will last somewhere around 7,000 - 8,000 hours, which should give a minimum of five years use before they need to be replaced.
