Motor Curve
Description:
1. The diagram below shows the relationship between the recommended motor output speed and torque when the ambient temperature is 30°C, with a 5 mm thick aluminum motor housing.
2. The chart compares the operating characteristics of the motor under different heat dissipation conditions: in air and in water.
3. The chart shows the characteristics at the nominal voltage. Increasing the voltage will shift the operating curve upward, while decreasing the voltage will shift it downward.
