Induction motor vfd torque curve
Webrelationship of slip to load and motor torque can be seen in the motor torque curve. National Electric Manufacturers Association (NEMA) design B motors are commonly used for pumps. The torque curve for design B as shown in Figure 7-33 has a dip on the left side of the peak but a nearly linear decrease in torque with speed on the right side of ...
