ABB 3BHB90211000595 ACS2000 Voltage Drive: Reliable Medium-Voltage Motor Control for Demanding Industrial Environments

Application Scenarios

At a major mining operation, three high-voltage motors handled continuous dewatering duties, but traditional direct-on-line starting caused severe grid voltage sags, and the pumps could not modulate flow based on sump level—wasting significant energy and accelerating mechanical wear. The maintenance team needed a speed control solution that could adapt to existing grid conditions without extensive motor infrastructure modifications. The 3BHB90211000595 as part of the ACS2000 platform integrated into the existing system through a simple “three-in, three-out” power cabling concept, using multilevel topology to deliver near-sinusoidal output waveforms. This meant existing standard induction motors could operate directly without derating or additional output filters . After commissioning, the pump station achieved automatic speed adjustment based on sump level, with single-pump annual energy savings exceeding 300,000 kWh, while grid voltage fluctuation issues were eliminated.

For chemical or water treatment facilities requiring harmonic compliance, the platform’s built-in Active Front End (AFE) technology keeps line-side harmonics within IEEE 519 and IEC 61000-2-4 requirements, eliminating the need for expensive dedicated harmonic filters and multi-winding transformers .
