The new original small geared motor should be an export toy machine core part. It is a 612 hollow cup motor through two-stage deceleration, and the final output is a large gear (outer diameter 20.7 MM, 39 teeth, 0.5 modulus), the workmanship is quite delicate.
This geared motor is composed of two-stage reduction gears. The first group of reduction gears is installed in the box. The start is a set of worm gear reduction, and then three gears are used to reduce the speed. The second-stage reduction is exposed outside the box, with only a large A small two gears decelerate.
There is no information on the motor in stock. We test the machine and feel that it is more suitable for operation between DC3V-3.7V.
DC 3 V No-load current: 15 MA Speed: 19.5 rpm
DC 3.7 V No-load current: 16 MA Rotation speed: 24 rpm
