Compole role is to improve the commutation, reduce the commutation spark when the motor runs between the electric brush and the commutator possible, generally installed between two adjacent main magnetic poles, the commutating pole core and commutating winding, insulating compole winding wire winded, set in the interpole core, commutating pole number from the main pole equal.
Two, the main pole
The role of the main pole is to produce air gap magnetic field. The main pole is composed of two parts: the main magnetic pole core and the excitation winding. The core of general use 0.5mm ~ 1.5mm thick silicon steel lamination riveting pressure tight, is divided into two parts pole and the pole shoe, the above set of excitation winding part called pole, following widening part called pole, pole width to the body, not only can adjust the distribution of magnetic field in the air gap and, at a fixed excitation winding. The excitation winding is made of insulated copper wire and is sheathed on the main pole core. The main magnetic pole is fixed on the base plate by screws.
Three, stand
The motor stator shell is called the base, the base has two functions: one is used to fix the main magnetic pole, commutating pole and an end cover, and supporting and fixing the motor; two is a part of the base itself is the magnetic circuit, so as to constitute a pathway between the magnetic pole, the magnetic flux through the part called magnetic yoke. In order to ensure sufficient mechanical strength and good magnetic properties of the base, it is usually made of steel or welded by steel plates.
Four, brush device
Brush device is used to introduce or lead to DC voltage and DC current, the brush device is composed of brush, brush holder, brush rod and brush holder. The brush is arranged in the brush holder and is pressed by a spring, so that the brush and the commutator have good sliding contact, and the brush holder is fixed on the brush rod. The brush rod seat is arranged on the end cover and bearing cover, the circumferential position can be adjusted, adjusted to be fixed after.
