## Description

Ideal for linear actuator movements, this DC geared motor delivers high torque at low speed, operates at 6V and reaches 100RPM without load. It has an output shaft in the form of a 100mm M4 threaded rod, easy to use with an M4 nut for converting rotation into displacement. Compact metal construction, weight approx. 40g.
GA12-N20 motor powered at 6VDC, with a 100RPM reducer, and with a 100mm M4 threaded rod as the shaft, ideal for linear control applications that require high torque and low speed.
The motor operates at 6VDC, providing a no-load speed of 100RPM through the reducer.
The 100mm long shaft is M4 type and can be used together with an M4 type nut for linear movements (like a linear actuator).
Specifications:

Use:
Connection: Make sure the power supply voltage is 6VDC. Check the correct polarity when connecting the wires. If output speed control is desired, it is recommended to use a PWM type module.
Avoid overloading to prevent the motor from overheating.
Periodically check the reduction mechanism and clean the related components to eliminate any blockages and extend the life of the motor.
