Starter armature manufacturer: Common sense of armature

　　 Starter armature manufacturer It indicates that the winding is the heart of the motor. Different motors, different manufacturers, and different processing technologies will correspond to different winding types. Different winding types are selected according to the specific characteristics to be implemented, requiring simple structure, convenient manufacturing and maintenance, and safe and reliable operation. The armature winding of a DC motor is the same as that of an AC motor. The relationship between the coils should make a certain number of conductors generate a large potential, saving non-ferrous metals and insulating materials as much as possible. However, it also has its unique features: the coils are connected by a commutator, and the connection relationship must ensure good commutation.

　　 The starter armature manufacturer said, The armature windings of DC motors can be divided into five types: single winding, lap winding, single wave winding, multiple wave winding, and frog winding, which is a mixed winding of lap winding and wave winding. A single lap winding is to connect the adjacent elements under the same magnetic pole in series, and the synthetic pitch y=yk=1 or -1. When winding this kind of winding, any two series-connected elements directly overlap the previous one, so it is called a lap winding. If y=yk=1, the winding moves to the right, which is called a "right-hand" winding; if y=yk=-1, the winding moves to the left, which is called a "left-hand" winding. Each element of the left-hand winding is connected to two short lines of the commutator, and more copper is used, so it is rarely used. Therefore, right-hand winding is often used in lap winding.

　　In a lap winding, if the corresponding element sides of two series-connected elements are not different by one virtual slot, but by two, three, or approximately M virtual slots, then correspondingly, the commutator segments connected at both ends of each element are not adjacent commutator segments, but are separated by two, three, or approximately M commutator segments. If the commutator segments are connected in series according to this rule, only half of the total elements of the armature can be wound each time. Obviously, the lap winding consists of two, three, or usually m single lap windings.

　　 The starter armature manufacturer said, The characteristic of a single wave winding is that the two commutator segments connected at both ends of each element are far apart, and the synthetic pitch y=yk is greater than y1. After two elements are connected in series, they are wave-shaped, so they are called wave windings. The difference between it and the lap winding lies in the commutation pitch yk: since the induced electromotive forces of the two series-connected elements should be in the same direction, the corresponding sides of the two series-connected elements should be under the same polarity magnetic pole, so the commutation pitch is approximately equal to two pole pitches. Its di pitch is close to or equal to one pole pitch, just like the lap winding.

　　In a wave winding, if P (pole pairs) elements are connected in series after winding around the armature, the commutator segments that are differentially connected are not adjacent to the starting commutator segment, but are separated from it by 2, 3, or M segments, then the resulting winding is equivalent to a combination of 2, 3, or M single wave windings, which is called a multiple wave winding.
