张文涛, 刘欣. Loss and Efficiency Analysis of Double Stator Toroidal Permanent Magnet Synchronous Motor[J]. Mechanical Science and Technology for Aerospace Engineering, 2025, 44(8): 1335-1343.
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.
