Frequently Asked Questions
What is the primary application for this 12V stepper motor?
This motor is specifically designed for high-precision applications such as telescopes and medical devices where a geared ratio is required for controlled movement.
What does the 120 geared ratio provide?
The 1:120 ratio increases the torque output to 160n.Cm while allowing for very fine incremental steps, ideal for low-speed, high-precision tasks.
Is this motor compatible with 5V systems?
While this specific model is rated for 12V, the series includes variations that can be adapted for different voltage requirements. Please check the resistance and current specs for compatibility.
What is the operating temperature range?
The motor is designed to operate efficiently within a temperature range of -25 ℃ to +55 ℃.
Why is there a magnetic inspection fee for shipping?
As the motor contains permanent magnets, international air transport regulations require a magnetic inspection to ensure safety during transit.
What is the mass and size of the motor?
The motor has a width of 35mm and a total mass of approximately 0.15kg, making it a compact solution for mini-automation.
