Many leading U.S. servo drive suppliers are gaining technologies and marketshare through acquisitions, dealing with consolidations and reorganizations, and competing for a growing motion control users population, according to the North America Servo Drive Outlook from Automation Research Corp.
Integral motors, a new breed of ac variable speed motors that embed drive electronics in the motor housing, are enduring harsh environments. Tony Carr, electrical engineer at Blue Circle Cement, says ABB Motors' design for its integral motor is best suited for his cement plant because the drive electronics are fitted at the motor's nondrive end—wher...
Energy efficiency is hardly a new theme. In a technologically expanding world, it has become crucial to come to grips with energy consumption yet still use energy wisely. A basic question to answer is, "Where can energy be saved efficiently"?Electric motors, particularly in industrial usage, represent a large portion of electric energy consumption.
Ongoing financial turmoil has shaken Asia's economies for the past seven to 10 months, and the region's ac drive business has slowed following major product reschedulings in Southeast Asia and South Korea, according to the recent AC Drive Outlook for Asia from Automation Research Corp.
If it didn't feature countless products, it wouldn't be the "world's largest industrial fair." More than 300,000 visitors examined products from close to 8,000 exhibitors during Hannover Fair '98. For instance, new motor and drive products included Lenze's 8200 Motec integral motor-drive unit, available in June.
Ringwood, N.J —RMB Miniature Bearings has integrated its 5 mm "smoovy" brushless dc motor with two smoovy planetary geartrains. The SPH50003 gearmotor comes with an 125:1 ratio. Continuous torque of 1.5 oz-in. at gearmotor shaft speed of up to 160 rpm provides smooth and high efficiency operation (60%) for a wide range of application.
Uxbridge, Mass. —SCF Series submicro adjustable frequency motor drives come in a wide range of sizes, all meant to fit into compact OEM designs. With power ratings from 1/4 to 3 hp, and input voltages of 120 and 240 single phase, and 208/240, 400/480, and 590 V ac (3-phase), these drives can fit into many applications, particularly in European markets.
San Jose, Calif. —Designed specifically for high operational shock and low power consumption, these 2.5-in. IDE silicon drives contain no moving parts and do not require constant power to retain information. Capable of surviving 1,000 Gs of shock (equivalent to dropping 8-ft. onto a hard surface), and providing 500,000 hr MTBF makes the silicon drive especially suited for industrial appl...
South Beloit, Ill. —Electrak 2000 hazardous duty linear actuator is designed for positioning applications in Class 1, Group D atmospheres such as paint booths or chemical processing. The step motor can handle a dynamic load of up to 625 lb at 1.5 in./sec and has a speed of up to 20 in./sec at 50 lb.
New Berlin, Wis. —MicroTrac3 contains an embedded PC designed to utilize Microsoft Windows NT and connect to MagneTek GPD 515 adjustable frequency drives. Featuring 4 MB of RAM, 2 MB of flash ROM, application library, and Ethernet and ARCNet communication support, MicroTrac3 is compatible with existing MagneTek networks.
