Desirable drives

If you could create the ideal adjustable speed drive, what would it include and what would it do?

Len • Bodine: The ideal ac motor speed control offers a combination of digital drive with some programming capabilities. The most common control functions we’re asked about are speed, torque, acceleration ramp, deceleration ramp, run, stop, direction, over-current protection, and speed read-out capability. Many of our customers want the “all-inone” solution as well; eliminating components and simplifying set-up is key.

Steven • Lenze-AC Tech: The ideal drive is, among other things, transportable, with preprogrammable memory, and available in a range of enclosure styles from chassis IP20 to fully enclosed NEMA 4X IP65; available in a range of powers up to 30 hp/22 kW; available in a range of voltages from 120 to 600 Vac for worldwide acceptability; and offers speed and torque control (sensorless vector technology) in a single package.

Rick • Baldor: The ideal drive supports all known communication interfaces, is easily programmed and modi ed, integrates simply with all known PLCs and building automation systems, neither fails nor trips, and costs 30% less than today’s average drive.

Chris • Leeson: Drives of the future will control both ac and dc motors equally. They will communicate and interface wirelessly to a control center as well as interface with other devices. This will allow for simple installation, maintenance, information processing, and  ne optimization. The end result will be improved productivity of entire facilities, beyond just applications.
