STRIM engineers have developed a new 125 kW asynchronous AC traction motor. The motor has compact dimensions: 612x420x416 mm. The size reduction was made possible by using a special liquid cooling system with increased heat transfer parameters.
New technical solutions were applied in the design of the frontal part and the design of the rotor.
To determine the engine speed, a two-channel sensor with a current output and a direction of rotation sensor is integrated.
Traction motor diagnostics and overheating protection are implemented on the basis of special temperature sensors, which allow monitoring the temperature state of bearing assemblies, slot and frontal parts of stator windings.
