Name: 500 Metal Gearbox Motor
Rated voltage: DC 3.7V
No-load current: 81 mA
No-load speed: about 48 rpm
Reduction ratio: about 85:1
Weight of a single geared motor: 95.8 grams
Uses: all kinds of DC fans shaking their heads and swinging wind, display stands, handicrafts, rotating lighting lamps, electric toys, etc.
Applicable voltage range: DC 1.5-6 volts
The no-load current measured at 3 volts is 71 mA, and the no-load speed is about 40 rpm;
The no-load current measured at 6 volts is 109 mA, and the no-load speed is about 75 rpm;
The new 500 geared motor, because the inside is a carton package, the motor and the cardboard are in direct contact,
The individual appearance is slightly imperfect, and the appearance requirements are strict and careful.
Disassemble and observe the metal reduction box, the front two-stage gears are plastic gears,
The purpose is to reduce noise, and at the same time, the force is also small;
Others are metal gears, which have the characteristics of wear resistance, no deformation, and large torque.
It can be driven by 1.5 volts, that is, a AA dry battery, with high efficiency;
As the voltage increases to 6 volts, the noise also increases.
When the power is off, the shaft can be twisted by hand; when the power is turned on, the torque is very large, and the pliers are difficult to stop.
The direction of the motor can be changed by changing the positive and negative poles of the power supply.
