A new brushless dc motor from MicroMo Electronics Inc. has an external motor-diameter of only 20 mm and a length of 57 mm. It provides high power-to-volume ratio by using a skewed winding in combination with a rotor made of Neodymium rare-earth magnets to provide cog-free motion. The brushless dc motor can achieve a continuous output torque up to 18 mNm at speeds up to 58,000 rpm. The motors come in a sterilizable version capable of withstanding an autoclave environment. The Series 2057 can be combined with a gearbox and encoder for a miniature dc drive system.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
