The given characteristics belongs to an AC servo motor... with varying the input voltage the position of graph shifts but the slope remains same
If you have any doubts please comment
Thank you
The graph (in red) shows a plot of the torque-speed characteristic of a motor running at 20 V Position the movable line...
Using the graph template or other means, calculate the no-load speed of the motor given the following table of results of a series of measurements of speed and torque of an electric motor. Speed rad s1Torque Nm 200.0 260.0 220.0 A00. 180.0 6oo. Drag and drop the markers provided (or use the arrow keys on your keyboard) to plot the three points on the graph then position the movable line in the same way to produce the speed/torque curve to...
A three-phase, 50-Hz, 4-pole, 575-V (line-line, rms) induction motor drive has a full-load (rated) speed of 1450 rpm. The rated torque is 50 Nm. Keeping the air gap flux-density peak constant at its rated value, (a) plot the torque-speed characteristics (the linear portion) for the following values of the frequency: 50 Hz, 40 Hz, 30 Hz and 20 Hz. (b) This motor is supplying a load whose torque demand increases linearly with speed such that it equals the rated motor...
