General specifications

Typical operating voltage: 3 V
Gear ratio options: 126, 441, 1543, 5402 :1
No-load motor shaft speed @ 3V: 12300 rpm1
No-load current @ 3V: 150 mA2
Stall current @ 3V: 2100 mA
Motor shaft stall torque @ 3V: 0.5 oz·in3
Color: gray

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.
