Motor Control for Wash-Down Applications

Dec. 19, 2007
The Allen-Bradley PowerFlex 40 AC drive and the ArmorStart product lines have packaging options that are now rated by NEMA and NEMA/UL Type 4X/12 (IP66/54) for indoor use.
Both products provide UL-listed protection against circulating dust and high-water pressure for equipment such as mixers, pumps, conveyor equipment, fans, packaging machinery, machine tool equipment, wood-working machinery and overhead door equipment. The NEMA 4X AC drive gives users decentralized vector control for applications demanding low-speed and high-torque control, and its National Sanitation Foundation (NSF) certification helps provide conformity with international food equipment standards. Available in 240, 480 and 600 volts for applications up to five horsepower (3.7 kW), the drive is also equipped with a configurable I/O including the ability to perform basic logic, timer and counter functions. The ArmorStart product line is also available in 240, 480 and 600 volts for applications up to five horsepower (3.7 kW). The NEMA 4X-rated distributed motor controller offers various starting methods that include full voltage, reversing, smart motor controller and variable frequency.  Rockwell Automation Inc. www.ab.com/drives800.223.5354
