For three-phase cage-induction motors, specifies eight new designations (Design N, NR, NS, NY, H, HR, HS, HY) relating to starting performance, and gives guidance on the determination of locked rotor kV.A and torque. For machines generally, specifies momentary overloads, and overspeeds.

This standard specifies general characteristics of rotating electrical machines.NOTE: Characteristics specific to synchronous generators are given in AS 1359.40.
