Characteristic Curve Data

First, the table below shows motor performance at different load points. Also, it helps users compare voltage, current, input power, output power, speed, torque, and efficiency.

In addition, current rises as torque increases. Therefore, the driver and power supply should be selected with enough current margin.

As a result, the highest listed efficiency is 47.47% at 166.1 rpm and 0.119 N.m torque. Moreover, the highest listed output power is 3.62W at 88.1 rpm and 0.3925 N.m torque.

Performance Curve Overview

Next, the performance curve image helps users review the relationship between speed, torque, current, power, and efficiency. Therefore, it is useful for choosing a safer working range.

Also, users should avoid using stall or near-stall conditions for long operation. As a result, real load testing is needed before mass production.

Curve Reading Notes

• First, no-load point: The motor reaches 203.6 rpm with 0.222A current.
• In addition, higher load: Motor speed drops as torque increases.
• Also, current rise: Current rises from 0.222A to 4.113A across the listed points.
• Next, best listed efficiency: The highest listed efficiency is 47.47%.
• Moreover, max listed output power: The highest listed output power is 3.62W.
• Finally, real testing: Confirm current, torque, speed, noise, and temperature under the real load.
