The article deals with the creation of traction motors with permanent magnets on the rotor. The possibility of creating a synchronous traction motor with permanent magnets on the rotor in the stator of asynchronous traction motor of passenger mainline electric locomotive is considered. The requirements to the parameters of the traction motor are defined, the size and location of the permanent magnets on the rotor are optimized. Optimization is performed using electromagnetic field theory methods. Based on the results of a series of magnetic field distribution calculations, the dependences of stator winding no-load current and electromagnetic torque on the load angle are plotted. Using these dependencies, the least-squares method, the parameters of the traction motor in question are determined. The obtained values of the stator flux capacitance created by permanent magnets, inductances along the longitudinal and transverse axes meet the formulated requirements for the parameters. Electromechanical characteristics and mathematical modeling of electromechanical processes at different rotor speeds were constructed. The obtained results allow us to conclude that a synchronous traction motor with permanent magnets on the rotor in the stator of an asynchronous traction motor of a mainline passenger electric locomotive can be made not inferior in its characteristics.
