A control device includes a drive control unit that performs control for driving the electromagnetic coil, and a regeneration control unit that performs control for regenerating power from the electromagnetic coil. The drive control unit includes an excitation interval setting unit that sets an excitation interval and a non-excitation interval such that voltage is applied to the electromagnetic coil during the excitation interval while not applied to the electromagnetic coil during the non-excitation interval. The excitation interval has a symmetrical shape whose center corresponds to a pi/2 phase point of the induced voltage waveform, and the non-excitation interval has a symmetrical shape whose center corresponds to the pi phase point of the induced voltage waveform. The regeneration control unit includes a regeneration interval setting unit that sets a regeneration interval and a non-regeneration interval such that power is regenerated from the electromagnetic coil during the regeneration interval while not regenerated from the electromagnetic coil during the non-regeneration interval. The regeneration interval has a symmetrical shape whose center corresponds to the pi/2 phase point of the induced voltage waveform, and the non-regeneration interval has a symmetrical shape whose center corresponds to the pi phase point of the induced voltage waveform.
