MicroMo Electronics' Smoovy series 0308-B brushless DC motor uses a skewed winding in combination with a rotor made of Neodymium rare-earth magnets to provide cog-free motion.
MicroMo Electronics has expanded 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.
It has an external motor-diameter of 3mm, a length of 8mm and a weight of 0.33g.
Electronic commutation means the service life of these motors is only limited by the bearings.
The brushless DC motor can achieve a continuous output torque up to 0.014mNm at speeds up to 15,000rev/min.
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 3mm diameter with various reduction ratios allowing a continuous output torque of up to 0.88mNm and up to 1.32mNm in intermittent operation.
The linear actuator consists of an 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 electronic synchronous drive servo amplifier with sine form output voltage that operates with PWM at 500kHz and with a power supply ranging from 2.7 to 5.5V DC.
