Long Screw Rod Metal Gearbox N20 Gear Motor with Hole Feedback, Left/ Right Hand, DC3V 3.7V Linear Gear Motor with Nut Slider-A Left hand

Package includes: 1 piece of motor

The product will be upgraded constantly, the appearance and color may be changed, please don't mind. And take a consideration before place the order if you have request for color or appearance.

The precision N20 geared motor has a long screw rod and an all-metal gear reducer. The tail of the N20 motor also has feedback for measuring the number of rotations. The length of the long screw rod has reached more than 50 mm. It should be used for precision electronic locks. Precision geared motors require precision control, so the motor tail has feedback for measuring the number of revolutions.

A geared motor: the screw is left-handed, and the pitch is 0.5MM.

Model B geared motor: The screw is right-handed, and the pitch is 0.35MM.

All-metal geared precision N20 geared motor, the geared motor of A type has a reduction ratio of about 1:306, and the geared motor of B type has a reduction ratio of about 1:240.

Because it is used in the drive motor of precision electronic locks, the tail of the N20 motor has a feedback control circuit for measuring the number of revolutions. We have not yet figured out the specific use of the control circuit. For buyers who do not use the control circuit It can be considered to lead directly from the positive and negative poles of the motor of the flexible wire, or directly weld the wires from the two pins of the motor.

In order to facilitate the DIY use by buyers, we have ordered a batch of nuts that can be used with the screw rod of the geared motor. When the geared motor is turned on, if there are parts that lock the nut and prevent the nut from rotating, the rod can drive the nut straight up and down. Move, then the geared motor becomes a geared motor that moves linearly.

The main difference between the A geared motor and the B geared motor is the difference between the straight tooth and the reverse tooth. As for the rear N20 motor and the speed feedback circuit on the tail, they are the same. The rated voltage is DC3.4V, and the applicable voltage is DC3V-3.7V. Now test the electrical parameters of the two geared motors at different voltages:

A geared motor:

The screw is counter-threaded, the nut is left-handed, the pitch is 0.5MM, and the reduction ratio of the gearbox is about 1:306. If the positive pole of the motor is connected to the positive pole of the power supply, and the negative pole of the motor is connected to the negative pole of the power supply, the direction of rotation of the screw is CW. If the nut is stuck, the nut moves downward. If the positive pole of the motor is connected to the negative pole of the power supply, the The negative pole is connected to the positive pole of the power supply. At this time, the direction of rotation of the screw rod is CCW. If the nut is stuck, the nut moves upward.

DC3V: The screw rotates at 58 revolutions, and the nut travels from beginning to end for about 90 seconds.

DC3.4V: The screw speed is 66 revolutions, and the nut runs from the beginning to the end for about 80 seconds.

DC3.7V: The screw speed is 73 revolutions, and the nut runs from the beginning to the end for about 75 seconds.

Model B geared motor:

The screw is thread, the nut is right-handed, and the pitch is 0.35MM. The reduction ratio of the gearbox is about 1:240. If the positive pole of the motor is connected to the positive pole of the power supply, and the negative pole of the motor is connected to the negative pole of the power supply, then the screw will rotate The direction is CW. If the nut is stuck, the nut moves upward. If the positive pole of the motor is connected to the negative pole of the power supply, and the negative pole of the motor is connected to the positive pole of the power supply, the direction of the screw rotation is CCW. If the nut is stuck, the nut It moves down.

DC3V: The screw speed is 73 revolutions, and the nut travels from beginning to end for about 110 seconds.

DC3.4V: The screw speed is 81 revolutions, and the nut travels from start to end for about 98 seconds.

DC3.7V: The screw rotates at 88 revolutions, and it takes about 88 seconds for the nut to travel from beginning to end.

Weight: 14 grams (two motors are similar)
