DEFINITION

Classification: 324/772

Motor or generator fault tests:

(under subclass 537) Subject matter including fault tests of (a) prime mover rotating electrical machinery; (b) rotating electrical machinery which changes mechanical energy to electrical energy.

(1) Note. This subclass includes the testing of an assembled motor or generator not elsewhere classifiable.

(2) Note. Subject matter for testing just the rotating part of a motor or generator is classified elsewhere in this

class. See the search note below.

(3) Note. Subject matter related to prime-mover dynamo plants is classified elsewhere. See the search note below.

(4) Note. Subject matter related to electrical motor or generator structure is classified elsewhere. See the search note below.

(5) Note. Subject matter related to signalling, recording, metering, or testing of systems of supply or control for an electric motor and the electric motor is classified elsewhere. See the search note below.

(6) Note. Subject matter related to indicating, signalling, recording, or testing a single electric energy generator having means to regulate or control the generator output is classified elsewhere. See the search note below. (7) Note. Subject matter related to systems of acceleration or speed control of DC motors is classified elsewhere. See the search note below.
