1. Armature Classification and Properties
divided armature winding and the armature winding current AC armature winding two categories. They are used in DC and AC motor.
The armature includes an armature core and armature windings, the armature winding is a circuit portion of the DC motor, is induced electric potential, produce electromagnetic torque of the electromechanical energy conversion portion (a generator of mechanical energy is converted into electric energy ). Both a portion of the main magnetic path of the armature core and the armature winding is a support member, it is embedded into the groove of the armature winding of the armature core. DC motor armature principle induced AC motor and substantially the same current in the DC motor armature windings are AC, DC is outputted through the commutator.
AC motors are induction motors (asynchronous motor) and the synchronous motor, an induction motor rotor according to squirrel cage type rotor structure is divided and wound rotor induction motor stator windings produces a magnetic field, the rotor windings electromechanical energy conversion.
is a synchronous machine rotor winding generates a magnetic field, the stator winding electromechanical energy conversion. Refers to the portion of the motor armature generally require external power. DC rotor armature, stator armature AC motor.
