Problems solved by technology

However, the existing air-core compensation pulse generators generally adopt a single-phase structure, and use the positive half cycle of the output voltage to discharge the load. The problem is that the motor speed is restricted by the pulse width of the output current. If the pulse width required by the load is longer, The speed of the motor must decrease, and it is difficult for the energy storage of the motor to reach the required index

specific Embodiment approach 2

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

[0028] The two-phase armature windings of the motor are arranged orthogonally in electric angle, and there is no magnetic field coupling, so the two-phase windings will not induce currents each other during discharge, and the output current of each phase is relatively independent, which is more conducive to pulse shaping, thereby realizing output The ideal trapezoidal wave pulse current required for a rail gun.

specific Embodiment approach 3

[0029] Embodiment 3: This embodiment is a further limitation of the two-phase air-core compensation pulse generator described in Embodiment 1. The A-phase armature winding 1 and B-phase armature winding 2 adopt slotless concentric windings , the coils that make up the windings are made of multiple Litz wires wound in parallel, and multiple coils are connected in parallel to form the windings.

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

Abstract

The invention discloses a two-phase air-core compensation pulse generator and a method for realizing pulse discharge thereof, relates to an air-core compensation pulse generator and a method for realizing pulse discharge thereof, and aims to solve the problem that the rotating speed of the conventional air-core compensation pulse generator is limited by the pulse width of output current. Stator armature windings adopt a two-phase structure, the electrical angles of the two-phase windings are orthogonally arranged, each phase of output current is relatively independent, pulse current is outputto a load after parallel superposition of respective rectifiers, and the pulse width is no longer limited by the half cycle of the motor; during discharging, the excitation winding induces current tocompensate the armature winding, the internal inductance of the motor is reduced, and the amplitude of pulse current is improved; through controlling a trigger angle, a free component of a load current is eliminated, and an ideal trapezoidal wave pulse current is output. The invention is used for outputting pulse current.
