- Assembly measures 5.4" x 2.8" x 2"
Ball-Bearing DC Motor
Good-quality Buehler DC motor with a brass worm gear drives two nylon gears which change speeds at regular intervals. Running without the nylon gears, the motor and worm gear maintain a constant speed, so the speed changes are probably a result of the cogs on the smaller gear having varying pitches or angles which slow the whole assembly. The larger, black gear, slows, almost to a stop twice per revolution at voltages under 12 Vdc. The black gear is 1.95” diameter and has a nib that provides back and forth reciprocating action. Also on the assembly is an optical switch which can monitor the rotation of the larger gear.
