Permanent magnet synchronous motors are increasingly used in the oil industry. These motors need to be made more energy efficient. To do this, it is necessary to optimize the rotor of a synchronous motor by changing the design through topological optimization. Designing an electrical machine as a heuristic process does not guarantee finding the best solution. Methods are needed that complement the experience and intuition of the designer to find the optimal (rational) solution. Topological optimization is currently performed using the finite element method to reduce mass and improve the stiffness of structures. The proposed method allows you to transfer topological optimization to electromagnetic processes in permanent magnet synchronous motors to determine the direction of magnetization and the size of permanent magnets, for a given mass-dimensional parameters. Optimization of the rotor of a serial permanent magnet motor based on a genetic algorithm is proposed. A new topology of the rotor of the motor was calculated and an increase in the torque was obtained by 18.2%, which indicates that topological optimization is promising for synchronous motors with permanent magnets.
