Description
Tamiya (#70097) Twin Gearbox DC Motor
Item No. KR02036
Tamiya’s twin-motor gearbox consists of two independent motors and gearboxes in one compact housing, making it perfect for small robots. You can assemble the gearboxes to have a 58:1 or a 204:1 gear ratio. The Tamiya twin-motor gearbox is a small (3-inch long) plastic gearbox. It contains two small DC motors that drive separate 3mm hexagonal output shafts. There are two ways to put the kit together: with a high-speed 58:1 gear ratio or with a slower 203:1 gear ratio. Either way, the motors provide plenty of power to drive any small robot.

Notes:
(1) A theoretical speed of the gearbox output shaft can be computed by dividing this speed by the gear ratio.
(2) This is the no-load current of the motor when disconnected from the gears in the gearbox; the no-load current of the entire gearbox with the motor connected will be slightly higher and will vary depending on the gear ratio.
(3) A theoretical torque of the gearbox output shaft can be computed by multiplying this torque by the gear ratio.
