Characteristics of a Traction Motor with Permanent Magnets on the Rotor and Its Potential Application in the Transport Industry

Purpose: To consider the potential use of synchronous electric machines with permanent magnets (IPMsynRM) as traction motors on railway electric rolling stock. The primary focus of this study is an analysis of the characteristics of the IPMsynRM electric motor, with the objective of identifying the potential for its utilization in rail transport. Methods: A comprehensive analysis was conducted of a variety of versions of electric machines, with a focus on their control mechanisms when employed as components of a traction electric drive. Results: It was determined that a synchronous reluctance motor with permanent magnets (IPMsynRM) can be utilized as a traction motor. This is due to the internal arrangement of magnets and non-magnetic holes in the magnetic circuit, which provide high specific power per unit of mass and volume, efficiency, reduced weight and enhanced starting torque. The IPMsynRM characteristics and features were summarized in the paper. The utilization of the engine in electric cars and trains is a subject of consideration, thus enabling its proposition as a potential engine for vehicles. Practical significance: The research results will be important for the transport industry, as they expand the understanding of the features of the IPMsynRM energy-efficient electric motor in the aspect of its use as part of a traction electric drive of the railway electric rolling stock.
