2-Speed DC Gearmotor and Wheel
Build your next bot with this affordable 2-speed DC gearmotor and wheel. The Tamiya motor comes as a kit, and is assembled in under 10 minutes. The gear train is built using either of two available speeds, 203.7:1 (low speed) 58.2:1 (high speed). The motor can be powered by 1.5-6 vdc. Rotation speed depends on gear ratio, voltage, and load, and is in the 60-200 rpm range. Sorry, we do not have torque ratings.
Weight of both the motor and wheel is 2.5oz (about 75 grams). Motor casing measures 2.75" long, by approximatyely 1"x1". The 100mm long hex shaft may be cut to length. Its position within the motor casing is adjustable by way of a set screw. The motor casing has two molded-in mounting tabs, which accept up to #6 machine screws, making this motor and wheel extremely easy to mount to your robot platform.
The balloon sport wheel is 2 1/4" diameter by 1 1/8" wide. The tire is all rubber, and has molded-in soft nubs for extra traction. The one-piece hub is white plastic, and may be painted. Get two motors and mount them opposite one another to provide the classic differential steering arrangement for your robot. Get four motors and construct a powerful 4WD robot bugy!
