MOTION CONTROL: Koford Engineering LLC has introduced a new line of 22-mm slotless brushless motors that offer the highest power density and efficiency in their class. They are available in two- and four-pole designs and with hall sensors or sensorless with power outputs 0.7 to 430W, speeds from 2,600 up to 201,600 rpm, and efficiencies up to 92 percent. Autoclavable and non autoclavable versions are available. The slotless design eliminates cog for more accurate positioning in medical robotics applications and provides cool operation at high speeds for surgical and dental tools. The four-pole configuration doubles the resolution for hall feedback speed control, improving speed resolution and servo performance for applications that do not use encoders due to space or cost constraints. Windings can be customized to customer requirements and shafts can be modified. Cannulated shafts are available. Matching High efficiency/high frequency hall and sensorless drives which do not require external inductors are also available. These can be custom programmed to user requirements. Applications include orthopedic and other surgical tools, dental hand pieces, pumps, blowers and surgical robots.
The fun factor continues to draw developers to Linux. This open-source system continues to succeed in the market and in the hearts and minds of developers. Design News will delve into this territory with next week's Continuing Education Class titled, “Introduction to Linux Device Drivers.”
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
