Traction Motor
Utilizing the design and manufacturing technologies we have cultivated since our founding, our traction motors provide high reliability even in harsh railway environments.
Our motors boast excellent durability against vibration, temperature changes, dust, and long-term use.

Features
-
Our high-efficiency, high-output traction motors make it possible to realize a compact size, light weight, and energy savings.Traction motors with output ratings from 50 to 400 kW can be manufactured.
-
Reduced lifecycle costs achieved by optimizing service life design and incorporating maintenance-friendly features.
-
Available in self-ventilated type with excellent cooling efficiency (open type) and fully-enclosed type (inner, outer fans) that is dust proof, generates minimal noise, and requires minimal maintenance due to its sealed structure.
-
The adoption of an intermediate lubrication structure and structure that allows bearings to be replaced without disassembling the motor allows a longer time before maintenance needs to be carried out.
-
Our traction motors can be used for high-speed trains such as the Shinkansen, general trains such as subways, trams (ultra-low-floor trams) and APM (Automated People Mover) systems.
