Magnetic suspension with integrated motor

A passive magnetic suspension acts as an electric motor with the introduction of lead means, such as motor windings, to harness and output the generated torque or voltage from the magnetic fields. The magnetic suspension consists of at least one magnetic element (typically a disc) fixed to a stator element (typically a shaft) and surrounded by two or more planetary magnets on the rotor. Having all magnet poles oriented in the same direction results in strong repulsion forces which provide the radial magnetic suspension. Segmenting the rotor magnet creates multiple unipolar magnetic fields, enabling additional possibilities in the introduction of windings to output the generated torque and provide motor function.
