  1. Check the appearance of the starter armature to ensure that its rotating parts are not worn or deformed, the cable connectors are not damaged, the terminals are not discolored, the armature insulator is not damaged, and the armature body does not have abnormal temperature rise, etc.

  2. Use a professional testing instrument to test its internal circuit to ensure that its resistance value has not changed, the insulation has not been damaged, the brush bristle length has not been shortened, the brush contact surface has not been discolored, and the armature structure has not been deformed, etc.

  3. According to the test results, if any problems are found with the starter armature, a new armature should be replaced in time to ensure that the car can start normally, while avoiding engine damage and unnecessary loss of repair costs.

  II. Starter armature maintenance

  1. Regularly check the starter armature, especially after long-term parking of the car, the armature status should be checked in time, and if there are any abnormalities, a new armature should be replaced in time.

  2. When the car is running, the engine should be checked regularly. Diesel vehicles should pay attention to checking the fuel system to ensure that the engine is working normally, so as not to affect the service life of the starter armature.

  3. If an engine malfunction occurs during the driving process, the car should be stopped in a safe place as soon as possible to avoid the engine from stopping, which is not conducive to the normal use of the armature.

  4. Avoid unnecessary disassembly of the armature to prevent damage to the armature components.

  5. Regularly inspect the car, check the engine condition, ensure the normal operation of the armature, and maintain the normal use condition of the armature.

  The starter armature is a key component in the car starting process. Correct detection and maintenance are the key to ensuring its normal operation. Correct detection and maintenance are required to ensure its normal operation and avoid unnecessary losses.

  1. Testing the starter armature

  Before testing the starter armature, the engine circuit board should be tested first to ensure that it is intact, so that it can be determined whether there is a short circuit. Secondly, the internal wiring of the engine should be tested to ensure that there is no damage, so as to ensure the normal operation of the armature. Finally, the insulation of the engine armature should be tested to ensure that the armature has not been burned out, ensuring the normal operation of the armature.

  2. Maintenance of the starter armature

  The maintenance of the starter armature can be divided into the following aspects: First, when repairing, the engine circuit board should be checked to ensure that the circuit board is intact; secondly, the internal wiring of the engine should be checked to ensure that there is no damage; finally, the insulation of the engine armature should be checked to ensure that the armature has not been burned out. If the engine armature is found to be damaged, insulating material can be used to repair it.

  3. Installation of the starter armature

  The installation of the starter armature needs to be carried out according to certain steps. First, the armature should be installed on the engine, and ensure that they are in full contact to ensure the normal operation of the armature; secondly, before installing the armature, the wiring on the armature should be connected to the engine to ensure the correct installation of the armature; finally, after the installation is completed, the connection of the armature should be checked to ensure the normal operation of the armature.

  4. Replacing the starter armature

  If the starter armature is found to be damaged, a new armature can be used for replacement. First, the damaged armature should be removed, and then the new armature should be installed on the engine; secondly, before installing the new armature, the wiring on the armature should be checked to ensure that they are in full contact; finally, after the installation is completed, the connection of the armature should be checked to ensure the normal operation of the armature.

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,
