The primary feature of this high-efficiency gear box is a worm gear, which locks the output shaft whenever the motor is not turning. The high gear ratios of 216:1 or 336:1 make this gearbox appropriate for small walking robots, lifting mechanisms, and other applications where high torque is desired.

General specifications

Typical operating voltage: 3 V
Gear ratio options: 216, 336 :1
No-load motor shaft speed @ 3V: 9400 rpm1
No-load current @ 3V: 150 mA2
Stall current @ 3V: 2700 mA
Motor shaft stall torque @ 3V: 0.97 oz·in3

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.
