Abstract
The invention relates to an axial-field permanent magnet compensated impulse generator with double contra-rotating rotors and belongs to the technical field of an impulse generator. The axial-field permanent magnet compensated impulse generator comprises a left rotor, a stator disc, a right rotor, two end caps and a shell. The left rotor, the stator disc and the right rotor are sequentially arranged in a hollow-square-shaped space formed by the two end caps and the shell along an axial direction. The left rotor along with one of the end caps and the right rotor along with the other end cap are in mirror symmetry on two sides of the stator disc. An air gap is formed between the left rotor and the stator disc, and another air gap is formed between the stator disc and the right rotor. The left rotor comprises a left rotor disc yoke, a left rotor permanent magnet, a left rotor compensation disc, a left rotor bandage, a left rotor shaft and a left rotor support. The stator disc comprises a stator support and a stator disc yoke. The double contra-rotating rotor compensated impulse generator is capable of solving the problem that the sizes of two motors are enlarged due to the fact that the two motors are arranged side by side and enabled to rotate reversely to counteract electromagnetic torque impact generated by the existing impulse generator during discharging.
