Part Number
Definition:
A GENERATOR CONSISTING OF A SERIES OF MOUNTED COILS SURROUNDING A ROTATING PERMANENT MAGNET OR A PERMANENT MAGNET AND A ROTATING ARMATURE. THE VOLTAGE OUTPUT IS DIRECTLY PROPORTIONAL TO THE SPEED OF ROTATION OF THE SHAFT. WHEN USED WITH AN ASSOCIATED INDICATOR, TRANSMITS SUCH DATA AS REVOLUTIONS PER MINUTE, SPEED OF TRAVEL, AND THE LIKE. MAY ALSO BE USED IN SERVOMECHANISM LOOPS AS A SYSTEM STABILIZER. EXCLUDES ROTARY INVERTERS, ROTARY CONVERTERS, MOTOR GENERATORS, DYNAMOTORS, GENERATOR SETS, SYNCHROS, FREQUENCY OR PHASE CHANGERS, AND ENGINE ACCESSORY GENERATORS.
