General specifications

Typical operating voltage: 3 V
Gear ratio options: 7.5, 9.5, 15.7, 19.9,
32.9, 41.8, 79.0, 87.8 :1
Free-run motor shaft speed @ 3V: 8400 rpm1
Free-run current @ 3V: 60 mA2
Stall current @ 3V: 600 mA
Color: clear

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.
