Miniature 10MM planetary gear motor DC2.5V-5V M10 motor rare earth strong magnetic medical equipment

Outer diameter of planetary gearbox: 9.9 MM
Motor specification: 8 1012 MM (M10 motor)
Geared motor height: 19.5 MM (motor + gear box)
Output shaft: 5.35 mm outer diameter gear (11 teeth)
Reduction ratio: 1:171
Weight : 4 grams
Rated voltage: DC2.5V
No-load current: 40 MA
No Load Speed: 92 RPM
Rated torque: 9.8 mN.m
Maximum torque: 37.2 mN.m

Power-on test machine, when DC2.5V, the sound is quiet, the power is OK, but not very powerful, this motor can also be pressurized to DC3V or 3.7V, if more power is needed, it can also be pressurized to DC4.2V, It can even be pressurized to DC5V. The higher the voltage, the greater the motor power, the faster the speed and the greater the torque. It is not recommended to work continuously for a long time at DC5V.

The following is the actual measurement of the speed of the motor under other voltages:
Voltage: DC3V Current: 42 MA Speed: 110 rpm
Voltage: DC3.7V Current: 48 MA Speed: 135 rpm
Voltage: DC4.2V Current: 52 MA Speed: 154 rpm
Voltage: DC5V Current: 58MA Speed: 180 rpm
