ベアリングレスモータ
Document Type and Number:
Japanese Patent JP5892628
Kind Code:
B2
Abstract:
Provided is a bearingless motor wherein torque and magnetic bearing power can be obtained by one type of winding. The bearingless motor is provided with a rotor (11) in which permanent magnets (17) are disposed in the circumferential direction so as to have predetermined magnetic poles, a plurality of stator teeth (13) which face the rotor (11), one type of winding (15) which is wound on the stator teeth (13) and has both functions of generating bearing power and generating torque, a power supply (20) which supplies an electric current to the winding (15), a rotation angle measurement means which measures the rotation angle of the rotor (11), and a switching control means which switches the value of the electric current to be supplied to the winding (16) so that the bearing power and the torque are selectively generated by the winding that is predetermined according to the rotation angle of the rotor measured by the rotation angle measurement means.
