Brushless DC Motor provides cog-free motion.

Press Release Summary:

With 3 mm external motor diameter and 8 mm length, Smoovy Series 0308...B combines skewed winding with jewel bearings and rotor made of Neodymium rare-earth magnets. Motor can achieve continuous output torque up to 0.014 mNm at speeds to 15,000 rpm. Due to electronic commutation, service life of motor is only limited by bearings. Series 0308...B can be combined with gearbox and linear actuator for complete miniature DC drive system.

Powerful, Lightweight Brushless DC Motor

Ø3mm Brushless DC Motor

Clearwater, Florida (June 28, 2007) - MicroMo Electronics, Inc. announces the expansion of its Brushless DC motor product line with the new version of the Smoovy Series 0308...B. This new version of the brushless DC motor 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 of the Series 0308...B brushless DC motor is now composed of jewel bearings. With an external motor-diameter of only 3 mm and a length of 8 mm and a weight of 0.33 g the motor is truly a microdrive. Due to their electronic commutation, the service life of these motors is only limited by the bearings. The brushless DC motor can achieve a continuous output torque up to 0.014 mNm at speeds up to 15,000 rpm.

The Series 0308...B Brushless DC motor can be combined with a gearbox and a linear actuator for a complete miniature DC drive system. The plastic planetary gearhead is available in a 3 mm diameter with various reduction ratios allowing a continuous output torque up to 0.88 mNm and up to 1.32 mNm in intermittent operation. The linear actuator consists of a M1.6 X 0.2 high precision lead screw and is ideal for positioning applications.

The Series 0308...B brushless DC motor can be driven by the FAULHABER BLD 05002 S Synchronous Drive Servo Amplifier. The BLD 05002 S is an electronics Synchronous Drive Servo Amplifier with sine form output voltage that operates with PWM at 500 kHZ and with a power supply ranging from 2.7 to 5.5 V DC.

Series 0308...B Brushless DC motors with 3 volt windings are immediately available from stock with a 24 - 48 hour turnaround.
