The Simulation Design And Application Testing on Permanent Magnet Motor of Trajectory Correction Device

According to the basic principle of trajectory correction ,this paper has analyzed the aerodynamic layout of the ballistic correction mechanism and through access to rele-vant data ,completed the design of permanent magnet motor in the ballistic correction mechanism ,and the influence fac-tors of the cogging torque of permanent magnet motor were analyzed ,and through the simulation analysis of permanent magnet motor ,it is concluded that the stator chute and slit width decreasing silicon steel sheet can reduce the cogging torque of permanent magnet motor.By using strain type of permanent magnet motor torque load device for actual meas-urement ,it is concluded that correct projectile flight when re-pairable period of permanent magnet motor torque is 20%greater than the wind resistance moment.Results show that the design of permanent magnet motor can meet the require-ments of precise control of steering gear.
