Abstract: Relevance. Improving electromechanical systems of vehicles. Purpose. Search for ways to increase the energy efficiency of traction electric motors (TEM) of vehicles. Methods. Comparative analysis, experiment, modeling. Novelty. An analysis of the operating conditions of a TEM as part of an electromechanical system consisting of a traction battery, an autonomous voltage inverter, and the TEM itself is conducted. The design features of the stator windings and inductor-tooth zones of asynchronous and synchronous electric machines are described, as well as features of the spectral analysis of the magnetomotive forces of the stator windings. Results. The proposed traction motor (TM) solutions, combined with adaptive vector control algorithms, enabled high efficiency across a wide TM speed control range with low electromagnetic torque pulsations. Practical significance. A proprietary TM design with increased efficiency across a wide speed range has been proposed. The authors' technical solutions can be used in the design of traction motors.
Keywords: vehicle, traction motor, inverter, winding, efficiency, speed, permanent magnet, harmonics, temperature
