Electrical switching & drive systems & components


Same day VSD solution

17 September 2020 Electrical switching & drive systems & components

When a manufacturing facility on the East Rand urgently required a replacement variable speed drive (VSD) for an extraction fan in its welding facility after the existing drive broke down and halted production, it turned to leading supplier Bearings International (BI) for a solution. Not only did BI have a 75 kW VSD available ex-stock, its technical department assisted the customer with the installation, integration and commissioning of the new drive so that it could be up and running on the same day. The VDrivePlus and AlphaDrive-Micro VSDs are electronic motor control solutions from Varispeed, available as part of its integrated solutions approach.

The VDrivePlus is specifically designed for all variable torque applications and ease of integration, with existing control configurations and ranges from 0,4 to 400 kW, available in 240 and 400 V. It features advanced motor control based on DSP technology, together with smart auto-tuning. Additional features include flexible inverter control, dual high resolution analog inputs and freely mappable I/O channels.

The AlphaDrive-Micro VSD is a compact frequency inverter ranging from 0,2 to 5,5 kW, and available in 240 and 400 V. Together with the VDrivePlus, these VSDs offer the best performance-to-cost ratio on the market, without compromising on quality and reliability.

These Varispeed VSDs can be easily supplemented with the Bauer electric motor range for applications from 0,18 to 355 kW, 400 V and 525/550 V. Applications include pumps, conveyor belts, sanding machines, cooling towers, crushers and pedestal drilling machines.
