General specifications

Typical operating voltage: 3 V
Gear ratio options: 41.7, 64.8 :1
Free-run motor shaft speed @ 3V: 9400 rpm1
Free-run 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.
