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.
