Abstract

Induction motors are used in industrial production processes. As for its use as a traction motor, it requires special design and manufacture. The type of induction motor that is widely chosen as a traction motor for railways is a squirrel-cage three-phase induction motor. The main consideration for the selection or design of an induction motor as a railway traction motor is the torque requirement to drive the train. Other parameters that are considered in the selection of an induction motor as a traction motor include available spaces for installation. This research is using a three-phase, 2,300 VAC, 480 kW, and 50 Hz induction motor. By using the application program for determining the parameters of the induction motor, it shows that the motor produces a moderate output coefficient (between maximum and minimum) and produces a torque greater than induction motor torque in general. As a result of the analysis, this induction motor is suitable to be used as a motor for the railway, where greater torque is required.

Abstract

This research is based on the development of a 480-kW traction motor for high-speed train (HST) applications. The performance of the traction motor system will be reviewed theoretically with the focus of the research on operational modes, namely acceleration mode and cruise mode. Motor performance will be reviewed more in-depth related to the development of mathematical models for torque function of time, power function of time and efficiency function of speed. The data used in this study are real data of 480 kW traction motor specifications and synthetic data of HST operations. The results of the traction motor performance analysis show that in the operational conditions of acceleration mode, the traction motor requires power and torque at the beginning reaching 4,838.13 Nm to overcome inertia, friction, aerodynamic force and increase speed. In cruise mode, the speed tends to be stable, so the power and torque decrease to 1,133.24 Nm. The results of the traction motor performance theoretically show that the traction motor can work well for variations in speed and track profile.
