Direct current generator recovery product structure analysis is worth noting; the structure form of the rotating motor must meet both electromagnetic and mechanical requirements, and the rotating motor must consist of two main parts: stationary and rotating.
1. The stationary part of a DC motor is called the stator.
Function -- Generates a magnetic field
Composed of the main magnet, commutator, base, and brush assembly, etc.
2. The rotating part of a DC motor is called the rotor (commonly referred to as the armature).
Function - Generates electromagnetic torque and induced electromotive force
Composed of armature core and winding, commutator, shaft, and fan, etc.
DC Motor Stator
1. A main magnet is an electromagnetic iron core, formed by tightly stacking and securing steel sheets of 1-1.5mm thickness.
Primary Magnet and Commutation Diagram
2. Directional Change (also known as Auxiliary or Intermediate)
Function -- Improve Directional Change
The directional assembly is installed between the two main magnets, consisting of an iron core and winding as well.
The core is typically made from a solid steel block or steel plate; the reversing winding is connected in series with the armature winding.
3. Base - The base is typically made of cast iron or thick steel plate, serving two purposes:
Fixed main magnet, reversing, and end cap
As part of the magnetic circuit. The part of the base where flux passes through is called the yoke.
4. Brush Assembly
Function - Introduce or extract DC voltage and DC current
Composed of carbon brushes, brush holders, brush holder bases, and copper braids
Direct Current Motor's Rotating Component
1. Two uses of armature core:
As the main component of the main magnetic circuit
Electrified armature winding, typically made by stacking sheets of 0.5mm thick silicon steel.
2. Armature winding
The main circuit of a DC motor, which converts mechanical to electrical energy by generating electromotive force through current and induction, consists of many coils connected in a regular pattern, along with components and their placement methods.
3. Reverser
Key component of a DC motor, function --- converts direct current passing through the brushes into alternating current within the winding or converts alternating electromotive force within the winding into direct current at the brush terminals.
