ABB takes motor starting to the next level with the innovative PSTX softstarter range
ABB´s PSTX softstarters will help reduce injuries with the built in motor break function
Hanover, April 13, 2015 – ABB, the leading power and automation technology group, will supply an advanced but still compact motor starting solution that has features that were previously only available with variable speed drives. Mid last year, ABB announced the introduction of the PSTX30…PSTX370 softstarters. The bigger sizes of the PSTX softstarter range, PSTX470…PSTX1250, will be commercially launched on April 13, 2015, at the Hannover Messe in Germany, the world’s largest industrial technology fair.
“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.
PSTX is also improving installation efficiency by providing integrated functionality avoiding additional devices and thus saving space and cost. A user-friendly and clear display saves time and resources during both setup and operation.
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. Find out more on http://www.abb.com/lowvoltage/launches/pstx.
