ÿ10 mm dc motor with precious metal commutation

MicroMo Electronics, Inc. has added the Series 1024...S to its DC Micromotor product line. With an external motor-diameter of 10 mm and a length of 24 mm, the unit combines the "System FAULHABER" ironless rotor and Neodymium rare earth magnets to achieve a stall torque of 2.89 mNM and speeds of up to 14,700 rpm.

The precious metal commutation allows operation at low starting voltages due to inherent low contact resistance. The series can be combined with a gearbox and encoder to create a miniature dc drive system. The planetary and spur gearboxes are available in both 10 and 12 mm diameter with various reduction ratios allowing an output torque up to 450 mNm.

The 2 channel magnetic encoders are said to allow for precise control of speed and direction of rotation as well as the positioning of the drive shaft.
