Motor Specifications

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

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

Suggested Operating Range

Next, the suggested operating range should be selected under conditions where the motor does not produce significant resonance. For testing, a stepper motor comprehensive testing instrument is recommended.

In addition, the recommended test mode is full-step drive mode with a 39 Ω motor winding. Therefore, the unlimited drive mode can be estimated with this reference formula: Voltage = Induced EMF + (Winding inductance × current) + (Winding resistance × current).

Moreover, the table below shows ratio, reduction precision, step angle, phase data, torque, and pulse rate. As a result, users can compare speed, torque, and position control before choosing a ratio.

As a result, lower ratios such as 1:42 and 1:115 provide faster output. However, higher ratios such as 1:1032 and 1:2006 provide finer step output and stronger detent torque.

Gearbox Performance

Furthermore, this stepper motor is integrated with a steel plate reinforced worm gearbox. As a result, it provides a rigid transmission structure with better durability and stronger resistance to high torque loads.

In addition, the robust gear train helps extend service life. Therefore, the motor can maintain stable performance in continuous or heavy-duty applications.

Because the motor is driven by pulse signal control, it can convert electrical pulses into precise angular displacement. For example, it is suitable for automation systems, smart devices, and applications that require repeatable digital motion control.

• First, when the drive frequency is high: The output torque decreases.
• In addition, when the drive frequency is low: The output torque is higher.
• Therefore, final selection: The final speed and torque should be selected according to the load requirement.

Input Electrical Parameters

Next, the following values show the input electrical parameters. In addition, the output shaft speed can be calculated by dividing the motor speed by the selected gear ratio.

Therefore, users can select drive voltage and frequency based on target speed, load torque, current, and heat rise. Moreover, real load testing is needed before production use.

Testing and Drive Notes

• First, for higher speed: Use a higher drive frequency within the stable range.
• In addition, for stronger torque: Use a lower drive frequency and confirm current rise.
• Also, for standard testing: Use DC 5.0V as the main voltage reference when matching the listed driver IC.
• Next, for gearbox output: Divide input motor speed by the selected ratio.
• Moreover, for holding control: Check locked-rotor current at 0 Hz.
• Finally, for safe operation: Confirm step response, torque, noise, temperature, and wiring stability under real load.
