DC Motor Requires Little Space

For tight-quarter applications, the RE 8 dc brush motor sports a diameter of 8 mm, length of 16 mm, and weighs less than 4g. Reportedly, the motor shaft is as thin as pencil lead at 0.8 mm in diameter and turns in two sleeve bearings. The shaft is ceramic and precious metal brushes ensure constant and low contact resistance between the brushes and commutator. Other features include low inertia, fast acceleration, no magnetic detent, and minimal electromagnetic interference. Planetary gearheads can be attached for certain applications where the given motor speed is too high and inertia too low. Additionally, the modular system can also provide a sensor for detecting speed and position. MAXON MOTOR USA, Fall River, MA. (800) 865-7540.
