Inverter drives reduce automation costs

Baldor launches a family of frequency inverter drives for AC motors that has the ability to reduce total cost of ownership substantially for common process automation equipment.

The drives offer a very simple user interface that provides ‘out of the box’ solutions for a large proportion of variable speed motor control applications. They are also available with a range of environmental protection, from a standard industrial housing to a dust- and splash-proof version (IP55 or NEMA 12), and even a full washdown duty (IP66 or NEMA 4X) variant. The latter version is unusual in this smaller power sector of the market.

The new Baldor VS1MX family of drives is expected to help machine builders to reduce costs substantially in automation for common applications such as fan and pump control, as well as in clean area processing zones in the food and pharmaceutical industries.

The drive range includes both single-phase and three-phase versions, for motor control power requirements from 0.37 to 7.5 kW (0.5 to 10 HP). A Modbus RTU communications port is provided as standard.

There are eight choices of drive available for single-phase applications, spanning motor output ratings from 0.37 to 2.2 kW (0.5 to 2.9 HP), plus a further 13 choices of three-phase versions for motor outputs from 0.37 to 7.5 kW (0.5 to 10 HP). All the drives also incorporate built-in analogue and digital I/O and a NOC relay output, providing users with facilities to create custom remote control panels, and to integrate the drive into a process.

The drives’ command parameters have been specially selected to provide a simple upgrade path for users of previous generations of low-power frequency inverters from Baldor.
