“…However, lowloss materials are sometimes used for high-performance motors. For example, the traction motors of the gauge-change trains [7] use M300-35A5. Figure 4 shows the calculation result [8] of energy loss in two traction motors in commuter train operation.…”

“…Application to the next generation commuter train was also examined because of the elimination of power loss and acoustic noise associated with the reduction gear [20,21]. Figure 15 shows the appearance and structure of the wheelmounted direct drive traction motor developed for the gaugeadjustable EMU [7]. Two wheel units integral with the traction motors slide on a fixed axle to adjust the distance between two wheels in order to enable through operation between different gauge track sections like standard gauge Shinkansen line and narrow gauge conventional line.…”

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. 

“…After the basic study on the gauge-adjustable train, the development project on the gauge-adjustable EMU for through operation of the Shinkansen and conventional lines was started in 1994 under the commission from the Japanese Railway Construction Public Corporation to the RTRI [12]. First, several types of traction motors were manufactured and bench-tested.…”

Owing to the resent progress in power electronics and permanent magnet materials, a permanent magnet synchronous motor (PMSM) that is lighter, smaller, and more efficient than the conventional induction motor has become realistic as a traction motor. We are making research and development effort on the introduction of the PMSM to rail vehicle traction. The recent development trend of the permanent magnet synchronous traction motor is reviewed. 

“…PMSMs have not yet been implemented as traction motors except for special examples [7], and the application of PMSMs to new-generation trains is now under study [8,9]. PMSMs offer high efficiency because there is no rotor loss, but they are suitable for compact design.…”

SUMMARYVentilated-type traction motors are widely used for railway vehicles. However, they require overhauls to clean inside them. In addition, they are a major noise source in railway vehicles. To solve these problems, we propose a totally enclosed-type traction motor using a permanent magnet synchronous motor that has the same weight power ratio as that of a conventional ventilated-type traction motor. In this paper, we report the test results of the proposed motor. The test results demonstrate that the temperature rise values are within its limit and the noise level is decreased by 10 dB compared to conventional motors.
