“…To achieve the speed higher than the nominal in the constant power mode, it is necessary to use the reactive component of the electromagnetic moment. It can be achieved for a deep arrangement of permanent magnets, as exampled by traction motors of electric rolling stock [14]. For a surface arrangement of permanent magnets on the rotor, this is impossible, since there is no magnetic asymmetry along the longitudinal and transverse axes.…”

The paper discusses the issues of creating a high-speed power generator for a low-power steam turbine. A 50 kW power generator with a rated speed of 12,000 rpm was developed. The influence of control parameters on the power generator performance was analyzed. The electromagnetic processes in the power generator were mathematically modeled. For the single-pulse control algorithm used in the generation mode, rational ratios of the angles of the beginning and end of the voltage pulse were established. The analysis of the obtained results shows that the developed power generator meets the set requirements for joint operation with a steam turbine. The choice of a valve-inductor machine for this purpose makes it possible to significantly simplify the design, reduce the costs of production and improves the reliability of the system as a whole. The peculiarities of the implementation of control algorithms make it possible to use a minimum number of sensors and not to use the rotor position sensor.

“…Usually, the sheets for the rotor iron core and the stator iron core are punched from a same magnetic steel sheet at the same time. Rotor of a permanent magnet synchronous traction motor [1] In the case of a PMSM, the rotor is composed of a rotor iron core and permanent magnets. The structures of PMSMs can be classified into interior permanent magnet structures and surface permanent magnet structures.…”

It is very important to improve the efficiency of traction motors to save energy in electric trains. In addition, improving the efficiency is also important to realize a totally enclosed traction motor that requires less maintenance. Therefore, the use of high-efficiency motors is expanding. Many of them are induction motors with high-performance materials; e.g. low-loss electrical steel sheets and low-resistivity conductors. Meanwhile, some of them use permanent magnet synchronous motors, which have higher efficiency than induction motors. In this paper, we will review these recent technologies to improve the efficiency of traction motors and give examples of high-efficiency traction motors in use in Japan. 

The performance of permanent magnet synchronous machines (PMSMs) has improved rapidly by the progress in elemental technologies such as electromagnetic material technology, computer-aided design technology, control technique, and drive circuit technology, and thus PMSMs are attractive as high-performance machines in various fields. This paper describes the recent technology and the trends in PMSMs. To begin with the PMSMs are classified by the ratio of magnet torque to the reluctance torque and their features described, then the trend of the motor design and the electromagnetic material for highly efficient PMSM is shown. The technologies that help to reduce the vibration and noise are also described, and the recently developed PMSMs for traction drive application are introduced. 
