Abstract
A compact high-efficiency motor is disclosed. The motor includes at least two rotor segments having passive magnetics comprising permanent magnets and at least two stator segments having active magnetics comprising permanent magnets and associated electromagnets controlled by a control system. The magnetic effect between the at two sets of magnetics can be modified to sequence the rotor segments through a series of rotation-induced steps by controlling the associated interaction of the magnetic fields produced by the two sets of magnetics. The electromagnets are energized by a control system to provide a variable-speed motor that produces high torque.
