摘要： A magnet unit includes a first magnetic pole (7a), a second magnetic pole (7b) and a third magnetic pole (7c) at a center between the first magnetic pole (7a) and the second magnetic pole (7b), providing an E-shaped configuration. In the magnet unit, a first magnet is defined between the first magnetic pole (7a) and the third magnetic pole (7c) by connecting two electromagnets (71aa, 73aa) with each other through a permanent magnet (72a), while a second magnet is defined between the second magnetic pole (7b) and the third magnetic pole (7c) by connecting two electromagnets (71ba, 73ba) with each other through a permanent magnet (72b). With this configuration, it is possible to reduce a deviation in the length of respective magnetic paths from the permanent magnets (72a, 72b) up to their respective magnetic poles. By controlling exciting currents to the respective magnetic poles. By controlling exciting currents to the respective electromagnets (71aa, 73aa, 71ba, 73ba), it is also possible to adjust fluxes (or flux density) in respective directions x, y individually.

摘要： An exciting voltage arithmetic portion calculates an exciting voltage of an electromagnet using a signal of a gap sensor. On the other hand, a sensorless exciting voltage arithmetic portion calculates an exciting voltage of the electromagnet using a signal of the current sensor. The exciting voltage adjusting portion adjusts a mixing ratio between an output value of an exciting voltage arithmetic portion and an output value of the sensorless exciting voltage arithmetic portion corresponding to a gap length. The excitation of the electromagnet is controlled according to an output value of the exciting voltage adjusting portion so as to reduce influences of noises on the gap sensors thereby always achieving a stable levitation control.
