An 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.

The standardized NEMA table of motor horsepower ratings runs from 1 hp to 450 hp. When an application’s horsepower requirement falls between two standardized values, the larger size is usually chosen. Horsepower (HP) = [Motor Speed x Torque (lb-ft) + 5250] HP = 0.746 x kW. kW = 1.34 x HP.
