要約(日本語): This paper explores a high-power consequent pole permanent magnet synchronous motor (PMSM) tailored for railway and heavy industrial applications, highlighting its distinctive radial suspension force characteristics. The study analyzes the volt-ampere (VA) requirements at the suspension winding terminals for a motor rated at 800 kW, with a maximum torque of 1700 Nm. A target radial suspension force of 2.8G (equivalent to 2.8 times the rotor weight) is set as a benchmark. Performance indices and VA requirements for the suspension winding are calculated across three distinct models of stator slots. The model demonstrating the lowest VA requirement and optimal performance indicates a need for further research into high-power bearingless motors.
