The difference between ordinary motor controller and hub motor controller

Generally refers to the hub motor controller. Brush DC motor controller stator magnet (or excitation coil), the rotor of the coil. As the current need to enter the rotation of the coil and the coil rotated 180 degrees due to be exchanged once the direction of the current flowing through the coil, therefore, used for brush DC motor controller connected to the body coil and current. Reversing the direction of switching bodies with a commutator and brush composition.

A hub motor controller generally coils on the starter by the rotation axis of the magnet mounted on the output drive shaft work. To solve the current problem for the use of Hall devices measured magnet pole position, the control circuit to external change, to change the current direction.
Hub motor controller because there are no brushes, long life, motor controller structure has been simplified.
