The rotor includes: a motor shaft, a silicon steel sheet, a copper strip (aluminum strip) or a copper wire winding and a copper head (slip ring) of type squirrel cage without conductive part and copper head.
Generator rotor The rotating part of the generator. It is mainly composed of rotor conductive windings, magnetic cores, rotor shaft extensions, retaining rings, center rings and fans. The generator rotor can be divided into two modes, one is pivot type and the other is rotating pole type. ① Pivot type: The magnetic poles are placed on the stator, and a three-phase symmetrical armature winding is installed on the rotor. When the rotor rotates, it cuts the magnetic field of the stator, induces a three-phase electric potential in the rotor and. uses three slip rings to output three-phase alternating current; this method generates electricityquoted. The power of the machine cannot be increased and is only used in the first small generators. ② Rotating pole type: the stator is equipped with a three-phase symmetrical winding, and the rotor is equipped with magnetic poles and excitation windings. Two slip rings are used to transmit DC excitation current to the rotor excitation winding to generate a constant magnetic field. When the rotor rotates, this magnetic field also rotates, and this rotation The magnetic field of the rotor cuts the three-phase symmetrical winding of the stator, and the three-phase symmetrical potential is induced in the three-phase winding of the stator. the output of this potential is a three-phase alternating current. As it is emitted by the stator and has no moving parts, the power can be very large and we get a wide range of applications.
