Variable speed drives

Latest News

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 wash down 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.

VS1MX drives have been designed to be as simple as possible to apply. Every version can be supplied ready to use, with an integral EMC filter. Simple front panel mounted user interfaces allow any of the drives to be made operational in minutes.

Baldor has launched 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.

Although the drives come with a control language of 45 parameters – supporting the programming of quite complex applications – the first menu level presents a subset that allows the most common applications to be set up in a few minutes.

These commands include motor voltage/current/frequency/speed, maximum/minimum speed, preset speed and acceleration/deceleration ramp. Configuration programs can also be stored on a simple external ‘memory stick’ type device, and reloaded as required. A remote keypad may also be fitted to the drives, to simplify the layout and construction of automation.

Despite the focus on economy, Baldor’s VS1MX drives offer an advanced new-generation V/Hz control algorithm that provides much tighter regulation of speed, and greatly improves torque at low speeds — making the drives capable of starting up even high inertia loads.
