A METHOD FOR REDUCING COGGING TORQUE OF INTEGRATED PROPULSION MOTOR

How to reduce the cogging torque of the jackie square toe ariat slippers integrated propeller motor is an important means to improve its noise performance because cogging torque is one of the key factors causing torque ripple.We proposed a method to reduce the cogging torque by optimizing the size of the Halbach array’s auxiliary pole.First,

This paper considers the problem of estimating the motion parameters of a low-observable high-speed maneuvering target with high-order motions, where the target’s complex motions will result in the range migration (RM) and Doppler frequency migration (DFM) effects within the observation time interval, which will significantly affect supercha
