Speed Control of Induction Motor using Variable Frequency Drive

This can be done either by varying the speed or varying the flow or pressure that is being created by the running motor. Since speed of motor is constant, there by providing the constant torque and thrust to flue gases. Thus the only option left and that is the variation in cross section. As flow increase, pressure at one side of the fan ...

Why diesel engines are considered steady torque engines?

The higher torque comes from a relatively longer stroke, which is needed to develop the higher compression for a diesel. The longer stroke gives a longer "arm" for the piston to push on the crankshaft. Or, think of the longer crankshaft throws; distance from crankshaft center-line to the throw center-line.

As the rotor accelerates to within a few percents of synchronous speed, both torque and current will decrease substantially. Slip will be only a few percents during normal operation. 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.
