3D Printed Linear Actuator | mini

Açıklama

The mini actuator's compact size enables integration into small-scale projects, such as robotics, drones, or medical devices; making it suitable for applications requiring accurate positioning or movement. The N20 gear motor and M4 lead screw combination offers a high force-to-size ratio, allowing for significant force output in a small package. Materials Needed - N20 gear motor - (1qty) - M4 nut and bolt (as lead screw) - (1qty) - 3D printed parts (actuator body, motor mount, and end caps) - 11mm OD , 4mm ID Bearings - (2qty) Assembly Process 1. Motor Mount: Attach the N20 gear motor to the 3D printed motor mount, ensuring secure fixation. 2. Lead Screw: Insert the M4 bolt into the 3D printed actuator body, threading the M4 nut onto the bolt. 3. Actuator Body: Assemble the actuator body, attaching the motor mount and end caps. 4. Motor Connection: Connect the motor to the lead screw (M4 bolt), ensuring smooth rotation. 5. Final Assembly: Complete the actuator assembly, adding bearings or bushings if necessary.
