Dc 3V 3.7V Screw Shaft Micro N20 Full Metal Gear Motor Nut Moving Up Donw Gear Motor Diy Lock

The length of the driver screw thread is about 10 mm. When the motor is running, the nut performs linear lifting motion, so it is also a micro linear motor. This type of small reduction motor is generally used as a lock core motor for fingerprint locks, robots, and shared devices. When the motor is running, the nut moves up and down in a straight line along the driver, but be careful not to let the nut rotate with the driver. There must be an object holding the nut to prevent it from rotating. Then, when the driver rotates, it naturally pushes the nut up and down. The length of the threaded part of the driver is about 10 mm. The terminal of the motor is a 5P socket, where the red and black wires are connected to the positive and negative poles of the motor, the yellow wire is connected to the screen ground wire of the motor housing, and the blue and blue wires should be external travel switches to control the switching of the positive and negative poles of the motor, in order to change the forward and reverse rotation of the motor and control the movement of the slider up or down. 1.Model:KM-1020FN20 2.Max length:20.3mm 3.Max width:20mm 4.Max thickness:10mm 5.Gear ratio:about 1:103 6.Rated voltage:DC 3.7V Size:as the picture show Package quantity:1Pc Note: Please allow slight differences due to manual measurement.
