Motor Specifications

First, the table below shows the main motor data. Also, it helps users check motor size, shaft size, phase data, step angle, frequency, voltage, weight, and wire sequence before sample testing.

Therefore, this compact stepper DC gear motor is useful when a product needs 5V power, precise step control, and stable gearbox output. In addition, users should confirm the wire sequence before connecting the driver.

Gear Ratio and Step Performance

Next, the table below shows the available gear ratios and output step data. Therefore, users can compare precise ratio, step angle, holding torque, and pull-out torque before choosing a model.

In addition, higher ratios provide smaller output step angles and higher holding torque. As a result, they are useful for fine low-speed positioning tasks.

As a result, lower ratios such as 1: 10 and 1: 20 provide faster output. However, higher ratios such as 1: 298 and 1: 380 provide finer positioning and stronger holding torque.

Ratio Selection Notes

• First, for higher speed: Choose 1: 10, 1: 20, or 1: 30 when faster output is required.
• In addition, for balanced control: Choose 1: 50, 1: 100, or 1: 150 based on the load.
• Also, for finer positioning: Choose 1: 210, 1: 298, or 1: 380 when smaller step angle is needed.
• Next, for higher holding torque: Choose a higher ratio when the product needs stronger holding force.
• Finally, for stable operation: Test speed, torque, step response, noise, and temperature under real load.
