Abstract
In this chapter, a traction system is presented, in which speed and load torque observers are implemented for diagnostic purposes. The presented solution is small part of developed bigger high-speed train (HST) predictive maintenance system. In the whole diagnostic system, several problems are under consideration, for example, speed sensor faults, mechanical transmission faults, and motor stator and rotor faults. With verified diagnostic criteria, the additional digital signal processors (DSP) diagnostic system is included into HST control system and works in closed loop mode. The presented diagnostic system concept is general in nature and is not limited to only HST induction motor drives. The implementation to other traction systems is also possible. Nowadays diagnostic systems are also under implementation for tramway vehicles and also for the newest traction drives with permanent magnet synchronous motors. This edition first published 2013
