Siemens Motor Control System Makes Trains More Reliable

Siemens has developed Sitrac, a new system for controlling the drive motors of rail vehicles. Sitrac requires fewer sensors, which reduces down time of the drive units and ultimately increases availability of trains. The system developed by Siemens rail technology experts in Erlangen is equipped with very robust control technology. The system recognizes the motor’s rotational speed, without requiring a rotational speed sensor, and uses the current converter to adjust the torque, and therefore also the rail vehicle’s traction. The picture above shows a commuter train in Shanghai which uses Sitrac.
