English: This is a brushed DC electric motor generating torque directly from DC power supplied to the motor by using internal commutation, stationary permanent magnets. Torque is produced by the principle of Lorentz force, which states that any current-carrying conductor placed within an external magnetic field experiences a force known as Lorentz force. The commutator consists of a split ring 20 degree shows magnetic force exerted on coil only when contact is establish, momentum makes the coil to continue to rotate when there is no current.
