No Soldering Board Step Gear Motor Parameters

Product Overview

First, the NFP-GM12-15BY-NW is a small stepper gear motor with a no-soldering board design. Therefore, it is suitable for compact motion systems that need easier wiring and stable step control.

In addition, this motor supports speed regulation and forward / reverse direction control. As a result, users can apply it to smart selfie sticks, smart camera pan/tilt units, robot camera corners, and intelligent micro robots.

Moreover, the compact 12mm gearbox helps save space. Therefore, it works well in small positioning systems and miniature automation modules.

Main Features

• First, no-soldering board design: The connection structure helps simplify assembly and reduce manual soldering work.
• In addition, 2-phase 4-wire structure: The motor supports standard stepper drive control for step-by-step movement.
• Also, forward and reverse control: The motor supports two-way rotation for camera pan/tilt and robot movement.
• Next, speed regulation: Users can adjust speed with a suitable stepper controller to match different motion needs.
• Moreover, custom shaft option: The output shaft length can be 4.4mm or 10mm, and custom shaft length is available when needed.
• Finally, compact gearbox: The 12mm gearbox helps save space in small smart devices and miniature robot systems.

Motor Specifications

First, the table below shows the main motor data. Therefore, users can check voltage, coil resistance, step angle, torque, drive mode, temperature range, and shaft options before testing.

As a result, this step gear motor can support compact control systems that need 5V rated power, 2-phase bipolar drive, and fine step movement. In addition, users should confirm shaft length and wiring before assembly.

Gear Ratio and Step Performance

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

In addition, a higher reduction ratio provides a smaller output step angle. As a result, it is useful for low-speed and higher-torque positioning tasks.

In conclusion, lower ratios such as 1:10 and 1:20 provide higher output speed. However, higher ratios such as 1:298 and 1:380 provide smaller step angles 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 motion: Choose 1:50, 1:100, or 1:150 based on the load.
• Also, for fine 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 use: Test speed, torque, step response, noise, and temperature under real load.

How to Choose This Step Gear Motor

First, choose the voltage and driver based on the control board. Also, confirm that the driver supports 2-phase bipolar drive and 2-phase excitation.

In addition, choose the gear ratio based on output speed and step angle. Therefore, lower ratios are better for faster movement, while higher ratios are better for fine positioning.

Moreover, check the output shaft length before mechanical design. As a result, users can choose 4.4mm, 10mm, or a custom shaft length based on the final structure.

Selection Notes

• First, for higher speed: Choose a lower reduction ratio, so the output speed will be higher.
• In addition, for higher torque: Choose a higher reduction ratio, so the output speed will be lower, but the holding torque will increase.
• Also, for compact designs: Check the output shaft length first, and confirm whether 4.4mm or 10mm is better for the product structure.
• Next, for stable control: Use a suitable stepper driver and verify the 2-phase 4-wire connection before power-on.
• Moreover, for no-soldering assembly: Confirm the board connection and wire direction before installation.
• Finally, for production: Test pull-in response, pull-out torque, holding torque, noise, and heat rise before mass production.

In short, the NFP-GM12-15BY-NW is a compact no-soldering board step gear motor for products that need 5V rated power, 2-phase 4-wire control, 18° step angle, 1:10 to 1:380 ratio options, and easier assembly.
