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.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
