[0002] In the existing two-axis compensation air core compensation pulse generator, the rotor excitation winding and the compensation winding are not on the same circumferential surface. Although in this structure, the direct axis compensation and the quadrature axis compensation can be designed separately, it will lead to the space utilization of the rotor. Low, and the excitation winding is far away from the armature winding, and the excitation efficiency is also low
[0003] On the other hand, after the air-core pulse generator discharges, a large amount of magnetic field energy is stored in the excitation winding. At present, this part of energy is generally not used, and is only lost in the form of heat through the excitation freewheeling circuit or the introduction of an external bleeder resistor. , which also makes it difficult to further improve the efficiency of the air-core pulse generator system operating in the self-excited magnetic mode
