Abstract
The rotor to be tested is placed in a test stator with a starting and working winding. A flywheel with a specified mass is mounted on the rotor shaft. The rotor is set in motion by stator windings, the starting winding excitation is disconnected after a specified time, and the rotor speed is measured at the disconnection instant. It is further measured at subsequent specified time intervals, and the number of rotor revolutions from start to the end of a specified time internval is counted. The measured speeds and the number of rotor revolutions is compared with specified nominal values.
