Speed-Torque Curve On large motors it is diffi cult and costly to measure directly torque versus speed at rated voltage In such cases the test is run fi rst to determine the shape of the speed-torque curve The curve is then calibrated utilizing the test results from the locked-rotor test to establish the actual speed-torque curve of the motor

[24/7 online]And on the other hand, when designed to have a high impedance, the motor has an increased amount of torque in a low-speed range In the area to the right of the maximum torque on the characteristic curve, increase in the load does not so much reduce the speed of low-impedance motors The torque increases and becomes stable
