Rail systems engineers have been tasked with creating an enhanced, high-powered electrical traction motor with torque density, which will help trains run more efficiently, consume less fuel, produce fewer emissions and reduce overall energy consumption.

Rail systems engineers have been tasked with creating an enhanced, high-powered electrical traction motor with torque density, which will help trains run more efficiently, consume less fuel, produce fewer emissions and reduce overall energy consumption.
To accomplish this, motor thermal performance must be improved. But this isn’t easy because metropolitan trains typically only have a small, confined environment to house a motor. As a result, motors are becoming increasingly compact and are required to produce more power in the same volume, leaving less space for cooling. Additionally, motors must be able to provide the specified power without overheating critical components and decreasing the operational efficiency. Not having an established methodology for assessing the motor’s thermal performance early in the design phase presented an obstacle that ABB engineers needed to overcome.
