Abstract

Double stator toroidal permanent magnet synchronous motor is a new type of spatial compound motor

which has the characteristics of low speed

high torque and good heat dissipation. According to the special spatial structure of the double stator toroidal permanent magnet synchronous motor

the inductance parameters of the motor were analyzed

and the mathematical model including the position Angle of the planetary wheel was derived. According to the complex motion of the rotor of the space motor

the motor loss is divided into revolution and rotation loss for analysis. Through the analytical calculation model of loss

the loss of each part of the motor is verified by simulation. Finally

the influencing factors of efficiency are discussed

and the efficiency characteristics of the motor are analyzed. The results show that the efficiency of the motor can reach more than 90%

and the operation efficiency of the motor can be effectively improved by adjusting the frequency and current of the input power.
