Abstract
An internally loaded universal motor has a stator, a rotor, brushes and a loading device for generating an internal load on the universal motor. The shaft has a commutator, and a rotor core adjacent to the commutator. The rotor core is electrically connected to the commutator and rotates within the stator. The brushes deliver electrical power to the commutator. The loading device prevents excessive rotation of the rotor when the universal motor has a low external load.
