Starter armature manufacturer: Common sense of armature

2022-11-21

   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.

What are the structural hotspots of a starter armature?

The starter armature moves the entire armature through the magnetic force of the magnetic poles, causing the drive gear to mesh with the flywheel gear ring. The armature of the starter is offset from the magnetic pole by a certain distance under the action of the reset spring, and the commutator is relatively long. The starter housing is equipped with an electromagnetic switch. Its magnetizing coil is controlled by the starter switch S. The movable contact is the contact bridge. The upper end of the contact bridge is longer and the lower end is shorter, so the starter circuit can be connected in two stages. The starter has three magnetic field windings. Among them, the main magnetic field winding with fewer turns is made of flat copper bars, and the other two fine wire windings are the series auxiliary magnetic field winding and the parallel auxiliary magnetic field winding (also called the holding coil). The starter one-way clutch generally uses a friction plate clutch. The working process of the starter armature is divided into two stages. The series auxiliary excitation winding mainly works in the first stage, and in the second stage it is almost short-circuited due to being in parallel with the main excitation winding; the parallel auxiliary excitation winding works in both stages, which not only increases the magnetic force attracting the armature, but also limits the no-load speed. (1) Engagement When the starter switch S is turned on, the electromagnet generates suction to attract the contact bridge. However, because the pawl rests against the blank, the contact bridge can only close at the upper end, and the series and parallel auxiliary magnetic field winding circuits are turned on. The current circuit is:

Starter armature: What is an armature?

The starter armature 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 that 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 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, i.e., 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 that in most generators, the field magnet is rotating and is part of the rotor, while the armature is stationary.

Starter armature: armature knowledge points

The armature manufacturer states that the armature plays a key and crucial role in the process of converting mechanical energy and electrical energy into each other. 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 armature is the part of a motor that has coils, and the coils move relative to the magnetic field. In a generator, an induced electromotive force is generated in the 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. The armature manufacturer states that in most generators, the field magnet is rotating and is part of the rotor, while the armature is stationary and is part of the stator. Motors and generators can be composed of a stationary armature and a rotating magnetic field or a rotating armature and a stationary magnetic field. The pole shoes and moving iron parts of permanent magnets or electromagnets and solenoids (especially when the latter are used as switches or relays) can also be called armatures. The armature manufacturer states that armatures are divided into two categories: DC armature windings and AC armature windings. They are used in DC motors and AC motors respectively. Including the armature core and the armature winding, the armature winding is the circuit part of the DC motor,
