specific Embodiment approach 2

[0027] Embodiment 2: This embodiment further defines the two-phase air-core compensation pulse generator described in Embodiment 1. The A-phase armature winding 1 and the B-phase armature winding 2 are arranged alternately along the circumference. The phase A armature winding 1 and the phase B armature winding have an electrical angle difference of 90°.

[0028] The electrical angles of the two-phase armature windings of the motor are arranged orthogonally, and there is no magnetic field coupling. Therefore, the two-phase windings will not induce currents to each other during discharge, and the output current of each phase is relatively independent, which is more conducive to pulse shaping, thereby achieving output Ideal trapezoidal pulse current required by railguns.

specific Embodiment approach 3

[0029] Embodiment 3: This embodiment further defines the two-phase air-core compensated pulse generator described in Embodiment 1. The A-phase armature winding 1 and the B-phase armature winding 2 adopt slotless concentric windings , The coil that composes the winding is composed of multiple strands of Litz wire, which are connected in parallel to form the winding.

[0030] The A-phase armature winding 1 and the B-phase armature winding 2 are wound in parallel with Litz wire, which can effectively reduce the skin effect during discharge, reduce the internal resistance of the motor, and improve the efficiency of the motor; the armature winding coil uses the mold and the ring Oxygen resin molding, epoxy resin plays the role of shaping and strengthening; for windings with no slot structure, it is easier to wind and arrange with concentric winding.

Abstract

The invention relates to a two-phase hollow-core compensation pulse generator and a method for realizing pulse discharge, and aims to solve the problem that the rotating speed of the conventional hollow-core compensation pulse generator is restricted by the output current pulse width. According to the two-phase hollow-core compensation pulse generator, a stator armature winding adopts a two-phase structure, the electrical angles of the two-phase winding are orthogonally arranged, the output current of each phase is relatively independent, the two phases are parallelly connected and superposed through respective rectifiers and then output pulse currents to a load, and the pulse width is not limited by the semi-period of a motor; during discharging, an excitation winding induces the current to compensate the armature winding, so that the internal inductance of the motor is reduced, and the amplitude of the pulse current is increased; and free components of a load current are eliminated by controlling a triggering angle, and an ideal trapezoidal wave pulse current is output. The two-phase hollow-core compensation pulse generator is used for outputting the pulse current.
