What Is A Hub Motor Exactly?

Hub motors are a kind of DC motors that are different from others because they do not have a commutator and brush mechanism to generate power in the windings.

In a hub motor, the stator remains still and is made up of a core and slots where copper windings are placed.

Most hub motors use trapezoidal windings.

To ensure proper commutation, an external driver circuit is responsible for supplying a DC pulse to the stator windings, allowing each slot to be magnetized at specific times.

The inside of the rotor has a series of magnets or permanent magnets arranged in alternating magnetic fields (north-south-north-south).

Hub motors work on the same principles of electromagnetism as induction motors, where electromagnets and permanent magnets attract and repel each other.
