3313 Development of Permanent Magnet Synchronous Motor Drive System for High Speed Train over 400km/h Speed

Abstract

This paper describes the development of Ihe new propulsion system utilizing permanent magnet synchronous motor for high − speed train over 400km 〆 h speed ， Deve 置 opmen 【 concept and feature of the developed equipment is described in detail． High e 齟 ency of 山 e permanent magnet synchronous rnotor enables to employ the self −ventilation with 血 e equlvalent size to that of the forced ventilation induction motor and to save the motor blower space ． The test result shows the motor efficiency reaches 97％ and the developed system has adequate output power required to high speed train over 400krnth speed ， 陶 ％ r43 ：Permanent Magne 【 Synchronous Motor ， Traction Drive system ， High Speed Train

Energy Saving Technologies for Railway Traction Motors

“…For example, series E954 Shinkansen high-speed experimental train of JR East aiming at a commercial operation speed of 360 km/h employs a self-ventilated PMSM [23]. Figure 17 shows the appearance of the motor [23].…”

“…For example, series E954 Shinkansen high-speed experimental train of JR East aiming at a commercial operation speed of 360 km/h employs a self-ventilated PMSM [23]. Figure 17 shows the appearance of the motor [23]. Continuous rated output of the motor was 355 kW, and the rated efficiency was 97%, which is about 3% higher than that of the conventional induction traction Fig.…”

“…17. Permanent magnet synchronous traction motor for the high-speed experimental Shinkansen train of the JR East [23] motor [24]. By making use of the high-efficiency feature of the PMSM, the self-ventilated traction motor achieved the same size and mass as the conventional forced ventilation traction motor.…”

“…Alstom in France has manufactured a 120-kW (continuous rated Fig. 13 Permanent magnet synchronous traction motor for the high-speed experimental Shinkansen train of the JR East [15] output is 100 kW) PMSM for low-floor LRV Citadis [16]. In addition, Alstom is developing a 720-kW (continuous rating) PMSM for the next generation highspeed train AGV with a maximum speed of 350 km/h [16].…”
