Sensorless AC Drives Fill Price/Performance Niche

KEY WORDSMotors, drives, & motion controlAC variable-speed drivesAC induction motorsAdaptive controlControversial right from their name, "sensorless" ac drives actually use current and voltage sensors to achieve motor control. Even beyond terminology, it's not obvious what sensorless ac drives can or can't do, and where they fit into the big picture.

Model, Simulate, Execute Simulation in Discrete Control

KEY WORDS PC-based control Machine control Software for control Flowchart programming Simulation Imagine a product design, completed in software, and rendered in 3-D graphics. This rendering allows designers to strip away layers to view and work on components underneath. Next, manufacturing engineers can design the machines, fixtures, and processes required to produce components and completed ...

Power remote sensing

Florence, Ky.—G-Power Remote Series pumps up the power of tubular M30 proximity sensors to support up to eight tool-mounted sensors and now provides a rotatable rectangular head version for difficult mounting situations. The product eliminates corrosion and damage-prone slip rings and mechanical connections to provide a "connector-less" hook-up transmitting power and signal to/from sensor...

Transmit torque through barrier

Addison, Ill. —MDC/MSV magnetic synchronous torque-limiting clutches transmit torque through housings, cabinets, or other sealed applications. Two disks (or cylinders) lined with permanent magnets oppose each other across the barrier and an air gap. "Servo-quality" torque is produced as one disk or cylinder rotates relative to the other.

‘Power of Industry’ will propel Hannover Fair 2001

Hannover, Germany—Twenty-five halls will be "in play" to accommodate this year's edition of the "world's largest industrial technology trade show" on April 23-28, 2001. An extra benefit is the fairground's upgraded infrastructure, completed for Expo 2000, the World's Fair. Hannover Fair 2001 combines six "fairs" in its "Power of Industry" theme.

Protect Plant Personnel

KEY WORDSMachine control and discrete sensorsSafetyRedundant controlControl architecturesManufacturing has been a dangerous place to work since the beginning. Even as engineers have tried to design safeguards and unions try to educate members about the importance of safety, as late as 10 years ago it was not unusual to walk around a factory and see guards taken off machines and safety switches ...
