Amplifier

Latest and greatest offerings in the engineering marketplace

By Design News Staff -- Design News, May 4, 1998

The 1-Q-EC 35V amplifier provides electronic commutation for brushless dc motors. Feedback is achieved via Hall-effect sensors built into the motor. Speed is determined via the bus voltage, eliminating the need for an additional signal voltage or potentiometer. Inputs select direction or disable power using TTL, CMOS, or a switch. The output power stage is designed using MOSFET technology. Supply voltage is 12 to 35V dc, with a 4V drop to the motor.

CAD/CAE Model Clean-Up: Reduce Iterative Cycles
This webinar featured research and survey results related to problems associated with preparing CAD geometry for CAE applications. We discussed how Recipe-Based Automation can help create "just-in-time" CAE-ready geometry each time a cad model is updated. Watch the Presentation

Light Matters: A High-Performance, "No-Compromise" Solid State Lamp?
First, let's define "no-compromise". In an ideal configuration, this lamp would use a high-brightness LED (HBLED) that is built into a small, integrated package, and is able to produce a large quantity of focused light, operate with a high level of reliability and generate no audible noise. Is this difficult? Yes, but it is possible.
