Product noteModular induction traction motors

What applications are these motors suitable for?ABB modular induction traction motors are used for distrib-uted power drive of a wide range of train types including light rail vehicles (LRVs), underground and overground metros, diesel or electric multiple units (DMUs or EMUs), high-speed trains (HSTs) and very high-speed trains (VHSTs).

What characterizes this motor type?This motor type is designed specifically to ensure reliable operation and high torque output as required in traction applications. The induction motor topology is a simple and robust design that has been proven to deliver high reliability in suburban and intercity traction applications, characterized by frequent starts and stops and high acceleration.

What characterizes ABBs motor range?Based on a single modular concept, ABB can design a variety of motor configurations using standard components. The modular concept simplifies the procurement, sourcing, design and manufacturing of these motors, while contributing to the motors compact design and high torque-weight ratio. Modular features include scalable design, different cooling methods and flexible bogie mounting arrangements. The motors are designed to endure extreme temperatures and polluted environments.

How is the motor customized?Each motor is designed and optimized for the actual train line profile in which it will operate, taking into account envi-ronmental and other running conditions. Motors are delivered according to specification regarding cooling method, mount-ing arrangement and other modular features. The motors are available in the 100900 kW range covering most low and medium power traction applications. See reverse page for motor performance charts.

What about service and support?Train operators benefit from simplified maintenance due to the motors modular design based on standard components. Support is provided from initial concept to maintenance. ABBs network of service workshops provides global cov-erage. The service organization has broad experience of electric motors, generators and their applications and can thus provide improved operational availability and life cycle profitability.
