Embodiment Construction
[0033] The drive device for the excitation coil of the online magnetic balance head provided by the present invention is used for driving the excitation coil of the "electromagnetic-permanent magnet" hybrid online active balance head of the rotating machine, and is mainly composed of a voltage regulation circuit and a current regulation circuit. The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.
[0034] The drive device for the excitation coil of the online magnetic balance head provided by the present invention is aimed at driving the hybrid magnetic force online active balance head of the "electromagnetic + permanent magnet" type. Since the driving waveform needs to conform to figure 1 (a) or figure 1 The waveform changes shown in (b) and the balance of different situations, so when the drive circuit is actually used, the corresponding control sign...
