Starting electric motors by connecting them directly to the grid (DOL - Direct On Line) or using classical star-delta methods causes them to draw massive inrush (startup) currents up to 7 to 8 times the nominal current at the moment of startup. This sudden power demand not only strains transformers and causes voltage drops in the grid but also the jerky mechanical loads imposed on the motor shaft, reducers, and conveyor belts rapidly consume the lifespan of the installation. Particularly in pump applications, stopping the motor suddenly creates a destructive "water hammer" effect in the pipes. If your process does not require continuous variable speed control and you only want to prevent these mechanical and electrical shocks during the starting and stopping of the motor, using soft starters instead of expensive frequency converters is the most appropriate engineering solution. As Şalt Elektromarket, we reduce your initial investment costs and protect your mechanical infrastructure with these critical automation products that tame the initial movement of your heavy industry motors.
Danfoss, a world giant in motor control and drive technologies, provides smooth acceleration with its VLT MCD series devices by controlling the voltage applied to the motor windings through thyristors with millisecond precision. Pipe bursts frequently experienced in massive pumps in water and wastewater facilities are completely eliminated thanks to the ramped stop algorithms developed specifically for pumps by Danfoss. Taking up much less space in the panel and radiating lower heat compared to drives (VFDs) running at full speed, these devices cut the current passing through them when the motor reaches its operating speed, thanks to their integrated by-pass contactors, offering significant energy savings and long life. As the Danfoss Product dealer with the strongest stock network and engineering infrastructure in its region, we make the most accurate soft starter selection for crushers, compressors, mixers, and industrial fans operating under heavy conditions and dispatch the devices directly from our shelves to your projects.
The flawless design of an industrial panel requires motor protection equipment to operate in complete synchronization with each other. Complementary switchgear materials such as motor protection circuit breakers and semiconductor (fast) fuses to be positioned at the grid input of the soft starter form the electrical firewall of your hardware. Şalt Elektromarket is not just a supplier making box sales; it is a leading Konya Electrical Materials Dealer that completely offers all the electromechanical components needed from the very beginning to the very end of the project under a single roof. We are always by your side with our original product guarantee and accelerated logistics network to fundamentally solve the motor startup problems in your enterprise, experience error-free commissioning processes, and multiply the lifespan of your system.
