MAGNETIC LEVITATION MOTOR

摘要

A magnetic levitation motor for rotating a rotor as levitated above a stator by a DC magnetic field and a stator winding. This motor comprises a DC magnetic field generating means (4) for generating a radial flux around the axis inside a stator (2) and a rotor (3), a first stator winding (6) for generating a levitation control flux (5) for controlling the rotor (3) to levitate radially, and a second stator winding (7) for generating a rotary field for rotating the rotor (3). The rotor (3) is provided with a yoke section (9) and a motor magnet (10) which face the stator core (8) of the stator (2), so that a part of a bias magnetic flux (11) and the levitation control flux (5) form a magnetic circuit which leads from the yoke directly to the stator core to increase the levitation force of the rotor.
