New family of dc brushless motors, controls

New dc brushless motors and controls from Baldor Electric Co. allow adjustable speed applications (mixers, blowers, indexers, feeders, and conveyors) to enjoy the benefits of brushless technology: higher torque and more power in smaller packages, reduced maintenance, and quieter operation. The new BMC series (BSM25C and BSM33C) controls provide a tight speed regulation better than 0.

New dc brushless motors and controls from Baldor Electric Co. allow adjustable speed applications (mixers, blowers, indexers, feeders, and conveyors) to enjoy the benefits of brushless technology: higher torque and more power in smaller packages, reduced maintenance, and quieter operation. The new BMC series (BSM25C and BSM33C) controls provide a tight speed regulation better than 0.5% and use the industry standard input command (+/- 10 V dc) or optional pot input for speed control. The controls use standard 115/208/230 V ac and are available from stock. The combination of BSM motor and BMC control is adjustable to cover a wide speed range to 7,000 rpm, provide adjustable acceleration time from 0.1– 30 seconds, and comes in a protected package including motor overload, short circuit and electronic inrush protection, etc. Typical adjustable speed applications include. www.baldor.com
