Controls field benefits from Compact PCI in telecommunications
The industrial controls market will likely benefit from decreasing prices, economies of scale, and technological improvements among CompactPCI-related products in the near future. These events are expected to occur as major vendors—including Ziatech, Digital, Force Computers, PLX Technology, Natural MicroSystems, and Spectrum Signal Processing—...
Extreme force linear servo motor
Hauppauge, N.Y.— Using an encapsulated oil cooling system for maximum heat removal, the LX Series provides an extreme force, iron-core-based linear servo motor, capable of 3,500 lb continuous force and 5,500 lb peak force. With simple two-part design, low inertia coil with magnetic attraction, compact size, and robust design, the LX Series linear servo motors is suitable for applications...
Champagne maker uses AS-i bus for decentralized control
To handle increasing production volumes, 150-year-old champagne maker G.H. Mumm recently adopted a decentralized AS-i bus architecture. The new system saves on wiring and installation costs, provides simple hardware integration, and will allow easy expansion, says Michel Hubert, technical director of G.
Baldor Electric buys Northern Magnetics
Baldor Electric Co. announced March 10 that it has acquired Northern Magnetics Inc. (Normag, Santa Clarita, Calif.) for an undisclosed sum payable in shares of Baldor common stock. Normag's range of linear motors will be added to Baldor's motor and drive lines, which range from 1/50 to 800 hp.
Electromechanical system design tool
Pittsburgh, Pa.— Electromechanical System Simulator (EMSS) software provides the designer with tools to analytically understand the interaction of currents, voltages, and mechanical loads and motion within an electromechanical device prior to its production. When used in design of electric motor systems, transformers, sensors, or actuators, EMSS uses time integration and nonlinear iterat...
Measuring and controlling instrument orders slip slightly in 4Q97
Despite ongoing and better-than-expected U.S. economic growth and manufacturing shipments, U.S. Commerce Department data showed that new orders in the aggregated Measuring and Controlling Instruments (SIC 382) industry group dropped slightly at the end of 1997.New orders in 4Q97 for SIC 382 firms rose by 7.
New Range of Brushless AC Servos
Andover, Hants, U.K.— The Unimotor range includes three phase, six or eight pole, permanently excited synchronous motors, exhibiting a sinusoidal back-EMF characteristic. Designed to supply high torque with either low- or high-rotor inertia and minimal cogging torque. Thermal performance is improved by the unique finned motor housing, manufactured in high-strength alloy casting to radiat...
Servo Amplifier
Westwood, Mass. Model 5424AC servo amplifiers internal power supply eliminates the need for a separate isolated dc power supply. Optoisolation between power and signal circuits ensures electrical safety. Users can switch the amplifier between velocity-mode and torque-mode with an external toggle switch or command from a programmable controller.
Intelligent Positioning Control
Lyman, S.C. —IPOS is an expansion card for the company's Movitrac 31C frequency inverter. The card gives the inverter the ability to control point-to-point motor positioning without use of a high-level controller, such as a PLC or motion controller. Using a built-in PLC-type logic, the Movitrac 31C offers capabilities such as timers, math functions, and timer and activation of outputs, a...
Step Motor and Drive
Torrance, Calif. —UFK Nanostep motor and drive package incorporates the latest 5-phase microstepping technology. Six 5-phase hybrid step motor models have been developed and matched to the UFK drive. Motors range from the UFK543AA which develops 18 oz-in constant torque over a speed range of 6 to 480 rpm to the UFK569AA, which generates 220 oz-in.
