DC Motors

Abstract

This animation helps you to grasp the direct current electric motor principle. No induction process is in action. Only the magnetic force acts upon a current loop. The sliding brushes permit us to maintain the rotation by fixing the direction of the current under each pole. Click on [play] or [pause] to play or stop the motion. Click on [next-image] to go on step by step. * To view the respective orientations of the magnetic field, the current and the force at any given time. * To understand the role of commutators and brushes.
