In industries such as food and beverage production, intralogistics or the machine industry, high-performance motors are used, for example, to drive conveyor belts and start equipment. In the event of their failure, serious damage can occur, so the motor starters that transmit energy to them play an important role in plants: they must also provide protection against overloads and short circuits. And in the food industry, where conveyor belt systems often need to be cleaned with high-pressure washing due to strict hygiene, water can easily cause short-circuits, leading to costly downtime.
Siemens’ new SIMATIC 200SP e-Starter motor starter, which detects the short-circuit current up to a thousand times faster than before, offers a solution to prevent this, and in the event of a fault, shuts down the equipment in 4 µs (microseconds). This ultra-fast and virtually wear-free switching compared to circuit breakers or fuses is made possible by the new starter using semiconductor technology with silicon carbide metal oxide semiconductor (SiC MOSFET) transistors.
Thus, once the cause of the shutdown has been removed, the device can be restarted immediately and offers unlimited shutdown shutdown. That is, in contrast to previous practice, there is no need to replace the device or purchase spare parts, and the availability of the plant can be increased.
The device with diagnostic functions, which requires minimal space and is easy to install, is integrated with Siemens’ development environment (Totally Integrated Automation – TIA) and has EcoTech certification. The latter, the company’s sustainability certification for the greenest solutions, was awarded to the motor starter due to the minimization of material consumption, as well as the device’s energy efficiency and durability.
The new engine starter is also available on the domestic market.
