DC Motors Gearbox Characteristic Curve

Motor Test Data

First, the characteristic curve data helps users review current, input power, output power, speed, torque, and efficiency under different load points. Also, it is useful for selecting a suitable working range.

In addition, the motor reaches higher output power at the middle load point. Therefore, users should test the real load before final product design.

As a result, the table shows how speed decreases as torque and current increase. Moreover, it helps users avoid overload conditions during product testing.

Performance Selection Notes

• First, check voltage: Use a 5V DC power supply for this motor.
• In addition, check no-load speed: Use 203.6 rpm as the listed no-load reference.
• Also, check load current: Make sure the driver can support the current under real load.
• Next, check torque: Use the curve data to match the required torque range.
• Moreover, check efficiency: Avoid using the motor near the end point for long operation.
• Finally, test real load: Confirm current, speed, torque, temperature, and service life before production.
