Definition of "Rotor" |
The rotating cylindrical member of a machine, placed inside the stator with a narrow intervening air gap to allow for smooth rotation. / The revolving part of a rotating electrical machine. The rotor may be either the field or the armature, depending on the design of the machine [Machine Rotor]. The rotating member of a synchro that consists of one or more coils of wire wound on a laminated core. Depending on the type of synchro, the rotor functions similarly to the primary or secondary winding of a transformer. A motor will use either an Armature Rotor or Squirrel Cage Rotor. / The rotor is the non-stationary part of a rotary electric motor, electric generator or alternator, which rotates because the wires and magnetic field of the motor are arranged so that a torque is developed about the rotor's axis. In some designs, the rotor can act to serve as the motor's armature, across which the input voltage is supplied. / A small rotating cap-like unit at the end of the distributor shaft. It is located on the breaker cam inside the cap. It connects between the center electrode and the various outer spark plug terminals as it turns, thus distributing the high voltage from the ignition coil secondary winding to the proper spark plug. / A voice frequency or voice band is one of the frequencies, within part of the audio range, that is used for the transmission of speech. In telephony, the usable voice frequency band ranges from approximately 300 Hz to 3400 Hz. / the rotating part of an electrical machine including the shaft, such as the rotating armature of a DC machine or the field of a synchronous machine. |
