ABSTRACT:
A machine for the automatic testing of electric motor rotors comprises a system for checking various characteristics of rotors arriving from a line of production thereof, in which system there are preset theoretical values of the various characteristics to be detected which are compared with the values detected on each rotor. Also provided in the machine is a display apparatus and/or a printer of the detected values, as well as a system of identification, in the tested rotor, of the type of characteristic whose detected value differs beyond an acceptable field of tolerance from the preset theoretical value.
