Description
This Standard gives specifications for general requirements for rotating electrical machines. This part covers built-in thermal protection for electric motors rated at 660 volts a.c. and below. the Standard describes limits of tolerance on efficiency, power factor, speed, torques, starting currents, transient and other reactances, voltage regulation and short circuit ratio of a .c. generators, exciter response and moment of inertia.
