Key Applications and Projects

• Automated Lifting Mechanisms: Building DIY motorized standing desks, TV lifts, or projector drop-downs where the self-locking feature prevents the payload from crashing down when power is removed.

• Heavy-Duty Rotisseries: Rotating heavy cuts of meat over a fire pit slowly and consistently without stalling.

• Smart Blinds & Awnings: Motorizing heavy outdoor patio awnings or large indoor blackout blinds.

Unlock New Capabilities (Project Evolution)

• The Automated Chicken Coop Door: An open chicken coop at night is an invitation for predators. Evolve your homestead by pairing this 10 RPM motor with an L298N Motor Driver, an Arduino, and a Photoresistor (Light Sensor). Because this motor is self-locking, a predator cannot pry the door open once it's closed. The Arduino can read the ambient light, automatically spin the motor to lower the door at dusk, and reverse polarity to open it at dawn!

ACCESSORIES / PACKAGE INCLUDED

• 1 x ASLONG PB-5840-31ZY 24V 10 RPM DC Worm Gear Motor

FREQUENTLY ASKED QUESTIONS (FAQ)

1. What is the operating voltage? This motor is optimized to run on a 24V DC power supply.

2. What is the output speed? It spins at a very slow, high-torque speed of approximately 10 RPM (Revolutions Per Minute) at 24V without a load.

3. What size is the output shaft? The shaft has an 8mm outer diameter.

4. What does "D-Shape" mean? The cylindrical shaft has a flat section machined into it (resembling the letter "D"), which prevents wheels or pulleys from slipping when a set screw is tightened against it.

5. What is a "Worm Gear" motor? It uses a screw-like gear interfacing with a spur gear at a 90-degree angle. This allows for massive gear reduction and high torque in a compact shape.

6. Is this motor self-locking? Yes. Due to the inherent friction of the worm gear design, the output shaft cannot be easily rotated by hand when the motor is off. It acts as a mechanical brake.

7. Can I reverse the direction of rotation? Yes. By simply swapping the positive (Red) and negative (Black) power wires, the motor will spin in the opposite direction.

8. What size mounting screws do I need? The gearbox face accepts standard metric M4 machine screws.

9. How deep are the mounting holes? The M4 threaded holes are approximately 6mm deep. Do not use screws that are too long, or they will grind against the internal gears.

10. How long is the actual shaft? The protruding shaft is 15mm long, with the flat D-cut portion taking up 13mm of that length.

11. Can I run this motor on 12V? Yes, a 24V DC motor will run on 12V, but it will spin at roughly half the speed (~5 RPM) and produce significantly less torque.

12. Is this motor waterproof? No, the metal housing and wire entry points are not sealed against water. It must be protected if used outdoors.

13. Can I control the speed of this motor? Yes, you can use a standard PWM (Pulse Width Modulation) DC motor speed controller to slow it down even further than 10 RPM.

14. What do the Red and Black wires do? Red connects to your positive power source (Power +), and Black connects to your negative ground (Power -) to spin the motor in its default forward direction.

15. What does the brand "ASLONG" mean? ASLONG is the manufacturer of this specific high-quality gear motor, as stamped directly into the metal gearbox casing.

16. Will this work for a DIY winch? It is excellent for small, slow-moving winches because the self-locking gear prevents the payload from unspooling the cable when you turn the power off.

17. What is the diameter of the black motor body? The cylindrical motor section has a diameter of 31mm.

18. Can I attach a wheel directly to this? You should use an 8mm Rigid Flange Coupling or a wheel hub designed specifically for an 8mm D-shaft to ensure a secure, balanced fit.

19. Does the motor get hot? Under heavy, continuous loads near its stall torque, the motor will generate heat. It is best used in intermittent applications or with adequate ventilation.

20. Can I manually turn the shaft to adjust my project? No. Because it is a worm gear, forcing the shaft to turn by hand will strip and destroy the internal metal gears. You must use electricity to move it.
