<p>The dual-flux magnetic field modulation motor shows significant advantages in improving the utilization of permanent magnets and torque density. However, when the torque ripple of the motor exceeds a certain limit, the operating stability of the motor is affected. In this paper, a dual-flux magnetic field modulation motor with interior-type permanent magnets and split teeth is proposed. The core objective of the design is to reduce the torque ripple, control the operating temperature of the motor, and enhance the operating stability of the motor. First, this paper describes the operation mechanism of the motor. Through a detailed analysis of the parameters, their influence on the main electromagnetic performance of the motor is discussed. Then, the genetic algorithm is used to finely adjust and optimize the structure of the motor. Finally, the proposed motor is compared with the conventional motor to verify the effectiveness and advancement of its design.</p>
