8.3.2 The Induction Motor (continued)
synchronous speed. This characteristic means that induction motors always run at slightly less than
synchronous speed in order to develop power - the ‘slip speed’ and, hence the term asynchronous. The
following graph is of an induction motor torque/speed curve and illustrates this most important
characteristic.

As for each type of motor, so each load coupled to an induction motor has its own speed/torque curve:
