ABB's PSTX softstarters will help reduce injuries with the built-in motor break function
2015-08-14
ABB has launched an advanced but still compact motor starting solution that has features that previously were only available with variable speed drives.
So far, ABB has introduced the PSTX softstarter range from PSTX30…PSTX370 softstarters to the bigger sizes PSTX470…PSTX1250.
“In terms of system and safety control, the integrated motor break function enables fast stop of a motor, which for example operates a circular saw or a fan. By reducing the stop time for the motor, lives can be saved as every second of rotation matters,” said Pietro Esposto, Global Product Manager for ABB´s Business Unit Control Products. “Also, the efficiency of the operation is dramatically increased as the process safety, especially for loads with high inertia, is improved.”
Securing the motor reliability is one of the main benefits provided by the PSTX range. As the inrush current to start electric motors is reduced by 60 %, less stress is put on the motor thus reducing the cost of maintenance and repairs. Over ten motor protections are included to keep motors safe from overloads and network irregularities.
Torque control, pump cleaning, jog with slow speed and many more features take motor starting to a new level. The torque control function for example is increasing application productivity by starting and stopping pumps while avoiding water hammering. The motor heating function avoids low starting temperature of the motor ensuring it to be always ready to start.
To facilitate the selection of the PSTX softstarter, ABB offers an online selection tool as well as a desktop application. Defining the parameters of your application and motor specifications the optimal softstarter is selected.
