WebAn induction motor's speed is always less than synchronous speed and it drops off as load increases. For example, for 1800 rpm synchronous speed, an induction motor might have a full-load speed of 1748 rpm. On standard induction motors, the full-load speed is typically 96% to 99% of the no-load speed. This is known as slip.
