Patent abstract
A multi-phase motor drive includes coil magnets that generate a magnetic field when energized with an electrical current. The coil magnets are configured in an electrical matrix. Switches are arranged in an electrical circuit with the coil magnets. Each coil magnet is in electrical communication with at least two of the switches and each switch is in electrical communication with more than one coil magnet. The switches operate in pairs to energize the coil magnets and the multi-phase motor drive includes a lesser number of switch pairs than coil magnets.
