Abstract
A direct current electrical machine, which includes a rotor that generates a rotor magnetic field, a first commutation cell that includes a winding component, a first switching device, and a second switching device. The first winding component includes a first portion electrically coupled between a first terminal and a second terminal of the first winding component and a second portion electrically coupled between a third terminal and the second terminal of the first winding component. The first switching device is electrically coupled to the first terminal and is closed when a first voltage induced across the first portion by rotation of the rotor magnetic field is positive; and the second switching device is electrically coupled to the third terminal and is closed when a second voltage induced across the second portion by the rotation of the rotor magnetic field is negative.
