Starter armature: What is an armature?

　　 Starter armature The manufacturer states that motors play a key and crucial role in the process of achieving mutual conversion between mechanical energy and electrical energy. For generators, it is the component that generates electromotive force, such as the rotor in a DC generator and the stator in an AC generator; for motors, it is a component that generates electromagnetic force, such as the rotor in a DC motor.

　　 The starter armature manufacturer states, The armature is the relative motion of the coil relative to the magnetic field of the coil-carrying component in the motor. In a generator, an induced electromotive force is generated in a forced rotating coil to generate electricity. In a motor, the energized coil is subjected to the Ampere force in the magnetic field, causing it to rotate in the magnetic field.

　　In the mid-19th century, the term "armature" was early used for inductors, that is, holders of magnets.

　　Part of an alternator or related equipment can be represented by any mechanical or electrical aspect. Although these two sets of terms are clearly separated, they are often used interchangeably, or a combination of mechanical and electrical terms is included. This can cause confusion when using composite motors such as brushless alternators, or when talking to people accustomed to using different configurations of motors.

　　 The starter armature manufacturer states, In most generators, the field magnet rotates and is part of the rotor, while the armature is stationary and part of the stator. Motors and generators can consist of a fixed armature and a rotating magnetic field or a rotating armature and a fixed magnetic field. The pole shoes of permanent magnets or electromagnets and the moving iron part of the solenoid (especially when the latter is used as a switch or relay) can also be called armatures.

　　Armature windings can be divided into DC armature windings and AC armature windings. They are used in DC motors and AC motors respectively.

　　 The starter armature manufacturer states, The armature includes the armature core and the armature winding. The armature winding is the circuit part of the DC motor, and it is also the part that induces electromotive force and generates electromagnetic torque for electromechanical energy conversion (the generator converts mechanical energy into electrical energy). The armature core is both part of the main magnetic circuit and the supporting part of the armature winding, embedded in the slots of the armature core.

　　The principle of induced armature in DC motors and AC motors is roughly the same. The current in the DC motor armature winding is also AC, and it is only DC when output through the commutator.

　　AC motors are divided into induction motors (asynchronous motors) and synchronous motors. Induction motors are divided into squirrel-cage rotors and wound rotors according to the rotor structure. Induction motors generate a magnetic field through the stator winding, and the rotor winding performs electromechanical energy conversion.

　　The synchronous motor is a magnetic field generated by the rotor winding, and electromechanical energy conversion is performed through the stator winding.

　　The armature generally refers to the part of the motor that needs an external power supply. The DC motor armature is the rotor, and the AC motor armature is the stator.
