Integrated traction system
Mitsubishi Electric offers an integrated "Traction System" comprising Traction Motor, Gear Coupling, and Gear Unit, designed to meet specific performance and bogie interface requirements. This system is backed by extensive experience, including over 80,000 units worldwide and insights from the Shinkansen (Japanese bullet train).
The traction motor is optimized for reliability and includes various types of induction motors. It benefits from Mitsubishi's broad experience in high-speed rail applications.
The gear unit features an optimum gear ratio with options for single or double reduction gears. It is designed to minimize interface complexity with the traction motor and is noted for low acoustic noise, drawing on experience from locomotives and EMUs.
The gear coupling accommodates large shaft misalignments with compact dimensions and maintains low acoustic noise. It is also informed by extensive experience with locomotives, EMUs, and the Shinkansen.
Mitsubishi Electric's integrated approach includes R&D, procurement, manufacturing, quality control, and design facilities. The company handles the interface design of the "Traction System," ensuring minimized design time and refined performance validation.
The document notes that specifications are subject to change without notice and provides a manufacturing record for both global and Japanese markets as of June 2022.
