PROBLEM TO BE SOLVED: To provide rotation driving equipment which can be made to operate a bearingless motor normally, even if a fault occurs. SOLUTION: This equipment consists of a stator 2, a rotor 3 rotatably supported magnetically, and a setting device 4. The stator 2 contains a drive winding 6, having at least two loops 61, 62 and a control winding 7 having at least three loops 71, 72, 73, 74. The loops 61, 62 of the drive winding 6 generate a driving magnetic field for generating a torque in the rotor 3, and the loops 71-74 of the control winding 7 generate a control magnetic field for adjusting the position of the rotor with respect to the stator 2. The setting device 4 supplies a phase current or a phase voltage as a setting parameter to each of loops (61, 62, 71-74). Since each loop (61, 62, 71-74) belongs to a different electrical phase, the setting parameter can be adjusted for each loop. |
