“…The permanent magnet synchronous motor, in constructive terms, is segmented in the literature into the following main topologies, represented in figure 1: SPMSM's (magnets placed on the surface of the rotor) and IPMSM's (magnets positioned inside the rotor), which have "U" and "V" subtypes (Duan, Ou and Deng, 2020) [6]. The internal magnet motor produces hybrid torque by both the magnetic and reluctance torque components (caused by the saliences), resulting in superior response and higher power density.…”

Enhancing efficiency has become a fundamental requirement across contemporary technological endeavors aimed at energy conversion. The imperative lies in achieving global energy resource preservation objectives. Novel methods of energy utilization with heightened efficiency are progressively gaining traction, accompanied by the intricacies of refining existing technologies. This research undertakes an examination of the amplified energy efficiency within regional rail systems, achieved through the adoption of permanent magnet synchronous motors (PMSMs) as primary electric propulsion systems, particularly when juxtaposed with induction motors. Delving into the theoretical engineering attributes of PMSMs, coupled with the establishment of dynamic motion characteristics and comprehensive simulations, offers a pathway to amassing empirical insights pertaining to efficiency studies.

“…Tagami et al [113] developed a motor shaft voltage model describing the imbalance between the stator winding and the frame and rotor. Duan et al [110] modelled the shaft voltage of the surface permanent magnet (SPM) motor and the interior permanent magnet (IPM) motor. Wang et al [114] developed a model of the motor that includes the insulation of the outer ring and the wire that connects the outer ring of the bearing to the frame.…”

The occurrence of the motor shaft voltage and bearing current caused by the inverter will aggravate bearing damage and lead to the premature failure of bearings. Many types of equipment are being shut down due to bearing currents, such as filters, insulated bearings and grounding brushes. Traditional suppression measures cannot eliminate the bearing current and the bearing damage mechanism under the bearing current is not clear. In this paper, the damage caused by the bearing current to bearings is analyzed in detail. The influences of different working conditions on the bearing current and the damage caused are discussed. The source of bearing currents is introduced and the bearing current model under different working conditions is reviewed. An outlook for future studies is proposed, based on the current research status and challenges.
