motor, it starts to turn, all by itself.

In brushless motors, this arrangement is

reversed. The electromagnets are on the stator,

and the moving rotor contains only unpowered

permanent magnets. No brushes are required.

Instead, the stator’s electromagnets are activated

electronically in the right sequence with precise

timing to “pull” or “push” the permanent

magnets in the rotor, thus making the motor turn.

The electromagnets in a brushless motor

are made by turning wire coils (called windings)

around the stator’s iron “teeth” (also called slots).

A brushless motor has three windings which have

to be wrapped around the teeth in
