PROBLEM TO BE SOLVED: To provide an electromagnetic suspension device capable of suppressing power consumption. SOLUTION: When an ABS(Antilock Brake System) control device and a VDC(Vehicle Dynamic Control) device are not operated (determined No in a step S14), namely, except for in emergency (determined Yes in the step S14) when there is a possibility of lowering traveling stability of a vehicle, the power consumption of a motor 3 is controlled to the upper limit value (limiting value) or less of the power consumption (steps S15-S17). This method can easily suppress the whole power consumption of the vehicle to a prescribed value or less. This can also prevent batteries from going flat and heating of a power cable. Furthermore, this method can suppress the temperature of a coil of the motor to a prescribed value or less except for in emergency so as to suppress expansion of the coil, reduce a gap between the coil and a permanent magnet, and improve the propulsion of the motor. This method can also suppress the rise in the peripheral temperature of the permanent magnet so as to reduce the possibility of demagnetization caused by the heat of the permanent magnet. |
