The motor diameter: 4 mm;
Length: 12 mm (not including the bearing sleeve)
Output shaft dia: 0.7mm;
The output shaft length: 4.5mm
Voltage: 3.7 V;
Current: 0.04 A;
Speed: 69000 RPM
(3V is 57000RPM, the current is 0.03A)
About speed, one thing to note: we test speed, no-load speed, because the plastic film speed measuring our, processed into a very light, the effect is negligible, (our data must be an electric motor that test).The hollow cup a small motor, load slightly different, speed will certainly change, so the load speed, each are not identical, we have no conditions can be tested. Also, the change of voltage, but also a direct impact on the speed of the motor, for example, when the voltage is 3 V, it will only turn 51000rpm.
