Frequently Asked Questions (FAQ)
Q1: What types of micro motors do you manufacture?
We design and manufacture a wide range of micro motors, including precision DC motors, stepper motors, reduction motors, planetary reduction motors, and brushless motors, tailored for high-precision and low-energy applications.
Q2: What reduction ratios are available for the GM12-N20 series?
The GM12-N20 series offers a wide spectrum of reduction ratios. For the 3.0V variant, ratios include 10, 30, 50, 100, 150, 210, 250, 298, and 330. For the 12.0V variant, the options range from 50 up to 1000.
Q3: How does the stalling torque scale with the reduction ratio?
As the reduction ratio increases, the output speed decreases, and the stalling torque increases. For instance, the GM12-N20-07310-12.0V has a stalling torque of 0.55 kg.cm at a ratio of 50, which increases up to 5.52 kg.cm at a ratio of 1000.
Q4: In which industries can these micro motors be applied?
Our micro motors are highly versatile and widely used in medical equipment, financial security, 5G applications, smart home systems, smart locks, intelligent robots, electric tools, and beauty apparatuses.
Q5: Are custom shaft lengths or gearbox modifications possible?
Yes, we support engineering modifications to meet various installation needs. The standard gearbox length for the GM12-N20 series is 9mm, but it can be configured to 12mm or customized for specific project demands.
Q6: What is the benefit of using planetary and reduction gearboxes?
Reduction gearboxes optimize output performance by increasing torque while safely reducing motor speed. This allows miniature motors to drive heavier mechanical loads reliably in compact spaces.
