Frequently Asked Questions (FAQ)
Q1: Is this worm gear motor self-locking?
Yes. This motor uses a worm gear reduction mechanism with a self-locking design, which means the output shaft cannot be back-driven when power is off. This is ideal for applications that require position holding without continuous power.
Q2: Can this motor hold a load when powered off?
Yes. Thanks to the self-locking worm gear structure, the motor can hold loads securely when power is removed, making it suitable for lifting systems, actuators, and positioning mechanisms.
Q3: What is the benefit of the dual shaft design?
The dual output shafts allow flexible mechanical integration from either side of the motor. This makes it easier to connect gears, couplings, encoders, or additional mechanisms depending on your system design.
Q4: Can this motor be speed-controlled?
Yes. The motor speed can be controlled using a compatible 24V DC motor controller or PWM speed controller, allowing smooth and adjustable speed control around the rated 12 RPM output.
Q5: Is this motor suitable for robotics and automation projects?
Absolutely. Its high torque, low speed, self-locking feature, and compact size make it ideal for robotics, automation systems, electric locks, conveyor mechanisms, and smart devices.
Q6: Does this motor include an encoder?
No. This specific model does not include an encoder. If your application requires position or speed feedback, consider pairing it with an external encoder or choosing an encoder-equipped worm gear motor from our store.
Q7: What power supply should I use?
A stable 24V DC power supply capable of delivering at least 1A current is recommended to ensure reliable operation under load.
