DriveStart - Medium-Voltage Soft Starter for Crusher

Motor Ratings:
3300V 2400kW

The main challenges of this on-site application are a weak power grid, the need for a high inertia start and a dynamic load change during the run-up phase (rotating hammers).

The DriveStart (SI-DST), our IGBT-based medium-voltage soft starter, is the right solution to these problems. It guarantees starting with high torque (1.5 – 1.8 x motor nominal torque) and a control that compensates for the required dynamic load changes while optimizing the starting current at the same time. SI-DST’s advanced digital monitoring and control program was able to start and control the engine without any problems, while ensuring the engine’s acceleration smoothly even under dynamic load changes.
