In a brushless DC motor, where is the magnet located?

In a brushless DC motor, the magnet is located on the rotor's shaft. This configuration is essential because it allows the rotor to turn without the need for physical brushes and commutators, which are typical in brushed motors. In brushless motors, the stator contains the windings through which current flows to create a rotating magnetic field. This rotating field interacts with the magnetic field produced by the magnets on the rotor, causing the rotor to spin.

This design improves efficiency and reduces maintenance needs, as there is less wear and tear compared to systems that use brushes. Additionally, positioning the magnets on the rotor helps in achieving higher performance, better torque-to-weight ratios, and smoother operation. The placement of the magnet on the armature (the rotating part of a motor) facilitates a more efficient design that enhances the overall functionality of the brushless DC motor.
