PERMANENT MAGNET SYNCHRONOUS MACHINE

摘要: PROBLEM TO BE SOLVED: To provide a permanent magnet synchronous machine, which is capable of attaining smaller space and more efficient use higher degree integration the quantity magnetism than motor or generator involving conventional magnetic bearing. SOLUTION: A stator coil 18 provided with current having waveform, produces not only driving torque for rotating rotor 12 but also bearing supporting 12. The waveform required operation added electrically inside controller 20 supplied to 18, so that this machine generates similar functions efficiently ones an independent winding winding.
