The Structure of DC Motor

The structure of a DC motor should be composed of two parts: the stator and the rotor. The stationary part of the DC motor when running is called the stator. The main function of the stator is to generate a magnetic field. It consists of a base, main magnetic pole, commutating pole, end cover, bearing and brush device. The rotating part during operation is called the rotor. Its main function is to generate electromagnetic torque and induced electromotive force. It is the hub for energy conversion of the DC motor, so it is usually also called the armature. It consists of the rotating shaft, armature core, armature winding, and converter. Composed of deflector and fan.

• Stator

(1) Main magnetic pole
The function of the main magnetic pole is to generate the air gap magnetic field. The main magnetic pole consists of two parts: the main magnetic pole core and the field winding. The iron core is generally made of 0.5mm ~ 1.5mm thick silicon steel plates, stacked and riveted. It is divided into two parts: the pole body and the pole shoe. The upper part with the excitation winding is called the pole body, and the lower part widened is called the pole. The pole shoe is wider than the pole body, which can not only adjust the distribution of the magnetic field in the air gap, but also facilitate the fixation of the excitation winding. The excitation winding is made of insulated copper wire and is placed on the main magnetic pole core. The entire main magnetic pole is fixed on the base with screws.

(2) Commutation pole
The function of the commutation pole is to improve commutation and reduce the commutation sparks that may be generated between the brushes and the commutator when the motor is running. It is generally installed between two adjacent main magnetic poles and consists of the commutation pole core and the commutation pole. Composed of pole windings. The commutation pole winding is made of insulated wires and is placed on the commutation pole core. The number of commutation poles is equal to the main magnetic pole.

(3) Machine base
The outer shell of the motor stator is called the frame. The base has two functions:
First, it is used to fix the main magnetic pole, commutation pole and end cover, and plays a supporting and fixing role in the entire motor;
Second, the base itself is also part of the magnetic circuit, which forms the magnetic path between the magnetic poles. The part through which the magnetic flux passes is called the yoke. In order to ensure that the machine base has sufficient mechanical strength and good magnetic conductivity, it is generally made of steel castings or welded by steel plates.

(4) Brush device
The brush device is used to introduce or extract DC voltage and DC current. The brush device consists of a brush, a brush holder, a brush rod and a brush rod holder. The brush is placed in the brush holder and pressed with a spring to ensure good sliding contact between the brush and the commutator. The brush holder is fixed on the brush rod, and the brush rod is installed on the annular brush rod seat. must be insulated. The brush rod seat is installed on the end cover or the inner cover of the bearing. The circumferential position can be adjusted and fixed after adjustment.

• Rotor

(1) Armature core
The armature core is the main part of the main magnetic circuit and is used to embed the armature winding. Generally, the armature core is made of 0.5mm thick silicon steel sheets punched and laminated to reduce the eddy current loss and hysteresis loss generated in the armature core when the motor is running. The stacked iron core is fixed on the rotating shaft or rotor bracket. The outer circle of the iron core has an armature slot, and the armature winding is embedded in the slot.

(2) Armature winding
The function of the armature winding is to generate electromagnetic torque and induced electromotive force. It is a key component of the DC motor for energy conversion, so it is called the armature. It is composed of many coils (hereinafter referred to as components) connected according to certain rules. The coils are wound with high-strength enameled wire or glass fiber-coated flat copper wire. The coil sides of different coils are divided into upper and lower layers and are embedded in the armature slot. The coils are The cores and the upper and lower coil sides must be properly insulated. In order to prevent the centrifugal force from throwing the coil edge out of the slot, the slot mouth is fixed with a slot wedge. The terminal portion of the coil extending out of the slot is bound with thermosetting glass tape without weft.

(3) Commutator
In a DC motor, the commutator is equipped with a brush, which can convert the external DC power into an alternating current in the armature coil, making the direction of the electromagnetic torque constant; in a DC generator, the commutator is equipped with a brush. The brush can convert the alternating electromotive force induced in the armature coil into the direct current electromotive force drawn from the positive and negative brushes. The commutator is a cylinder composed of many commutator segments, and the commutator segments are insulated with mica sheets.

(4) Shaft
The rotating shaft plays a supporting role in the rotation of the rotor and requires a certain degree of mechanical strength and rigidity. It is generally made of round steel.
