3V 5V 7.2V DC motor Carbon brush strong magnetic torque

Its applicable voltage is DC3V-DC12V. When DC3V, the sound is very soft, but the power is very good. It can't be blocked by hand. At DC6V-7.2V, the sound is soft, but the power is very strong. . When the voltage is increased to DC12V, the noise is a little louder, but at this time its power and torque reach its peak, which is called a "violent" 370 motor. Another point is that its carbon brush uses a copper carbon brush (very good copper content), so the normal service life of this 370 motor must be quite good.
