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.
