Lightweight Brushless DC Motor
MicroMo Electronics, Inc. announces its Smoovy Series 0308…B brushless DC motor. This version uses the System FAULHABER skewed winding in combination with a rotor made of Neodymium rare-earth magnets to provide cog-free motion. The bearing system is composed of jewel bearings. With an external motor-diameter of 3 mm, a length of 8 mm and a weight of 0.33g, the motor is really a microdrive. Due to its electronic commutation, the service life of this motor is only limited by the bearings. The motor can achieve a continuous output torque up to 0.014 mNm at speeds up to 15,000 rpm. It can be combined with a gearbox and a linear actuator for a complete miniature DC drive system.
