Propulsion System for DC Electrified Lines

We supply propulsion systems that cut power consumption and, are quiet and ecologically friendly.

These products are related to rolling stock drive systems that travel in a DC feed section. We offer high-efficiency systems including Permanent Magnet Synchronous Motors (PMSM)*1 and totally enclosed traction motors, and also offer a series of VVVF*2 inverters to drive these systems.

*1 PMSM : Permanent Magnet Synchronous Motor
*2 VVVF : Variable Voltage Variable Frequency

Features

Traction motors are vector controlled for highly responsive and accurate torque control. They also use electrical braking control down to a speed of 0 km/h, and the traction motor uses sensor-less control which eliminates the need for a speed sensor.

Benefits & Value

  • Highly efficient PMSM is used in the traction motor reducing energy consumption.
  • Installing a totally enclosed traction motor prevents internal contamination, and realizes cleaning not being needed for a long period of time.
  • The traction motor is constructed so that the bearings can be easily replaced without removing the rotor.
  • Using low-loss devices can be expected to provide a compact and lightweight VVVF inverter.
  • The use of a 4-in-1 unit can be expected to provide a compact and lightweight VVVF inverter for PMSM
