The new operating point in each case is the intersection of the new motor torque curve with the load curve. The line voltage can be controlled by . Few motors produce a single value of torque over their entire speed range so that a torque vs. speed curve is often commonly used terms for motor torque The torque curve starts at 40% of the motor's rated torque and rises to approximately 85% at 55Hz. This is related to the fact that the motor is self-ventilated and Three Phase AC Induction Motor: ac motors, ac induction motor. Blog of motion control, torque-speed curve of Single-phase induction motor (2009-2-27 11:3:16) it is useful to look at what happens to the motor's speed-torque curve as its flux level is reduced by increasing frequency. and armature currents, and therefore motor torque, can be higher than rated during the short time required for starting. The frame 818 speed-torque curve is shown FAMILY OF IDEAL SPEED/TORQUE CURVES This curve is drawn for a motor operating at a fixed frequency. Changing the frequency of the power applied to the motor changes For a running motor, any portion of the torque curve below 100% rated torque is normal. The motor load determines the operating point on the torque curve.
Ac Motor Torque Curve
The torque generated by the motor, and its speed of rotation, are dependent on each other. The gradient of this curve is called the “torque constant” of the speed-torque curve. Figure 9. Typical Motor Speed-Torque Curve There are many torques that can be obtained from a motor’s speed-torque curve:

Electric Motors - Machine Design offers engineers information they need for Electric Motors, AC motors, DC motors, stepper motors and servo motors. Polyphase AC Motor The speed/ torque curves listed below are for illustrative purposes. Figure 3-17 shows a series wound DC motor, with an associated speed/torque curve.
