Development of starter armature

2023-04-11

   Starter Armature It is a core component of the automobile engine starting system and an important part of automotive electronic technology. From the initial direct start to the current electric start, the development of the starter armature has gone through a long process.

  As early as the beginning of the 20th century, automobile starting used a simple hand-cranking method, then developed into more efficient pneumatic starting, and then into more popular and practical electric starting. The development of the armature part of the electric starter can be traced back to 1903 in the United States. At that time, an engineer named Frank J. Ward invented the electric starter. This electric starter consists of a set of armatures and a permanent magnet control switch.

  From the early to the mid-20th century, the armature part of the starter was still relatively simple. It usually consists of a motor, armature, water pipe, cam drive, etc. In 1948, Germany's Robert Bosch GmbH developed a wound-type starter armature. By the 1980s, the rapid development of electronic technology led to a huge increase in the demand for automotive electrical appliances. Semiconductor components and IGBTs began to be used in starter armatures. After a long development process, modern automobile starters are no longer simply motor parts, but multifunctional high-tech automotive parts.

  The starter armature is not only a key component for starting the automobile engine, but also has multiple functions, such as power generation, charging, emergency starting, external power supply, etc., supporting the intelligent and information development of automobiles. The development of the starter armature has profoundly affected the performance and stability of automobile engines and promoted the substantial development of the automobile industry.

  The vehicle starter is an important component. Its working principle is to generate magnetic force through the armature current to drive the engine to rotate. However, if the starter armature is used improperly, it may cause the vehicle to fail to start or damage the motor. To avoid this, the following precautions for the starter armature should be noted:

  The electrodes of the starter armature should meet the manufacturer's recommended standards. If inappropriate electrodes are used, it may cause armature damage or armature heating, affecting the normal operation of the engine.

  The starter armature should be cleaned and maintained regularly. If dust and dirt accumulate on the armature, it may hinder the current transmission of the armature and affect the vehicle's starting effect.

  The starter armature cannot be idled for a long time. If the starter armature rotates without current, it may cause armature damage, thereby affecting the normal operation of the engine.

  The current load of the starter armature should meet the standard. If the armature is overused, the current to the armature may increase, thereby damaging the armature or causing high armature temperature.

  Overuse or prolonged operation of the starter armature will cause the armature to overheat. If the armature is found to be overheating, stop using it and check whether the armature's current load exceeds the standard range.

How to properly test a starter armature? Maintenance tips for starter armatures

The starter armature is a key component in the process of converting battery energy into mechanical energy during car starting. It consists of numerous small parts. Due to its complex structure and working environment, its maintenance is relatively complex and requires correct detection to ensure its normal operation and long lifespan. I. Correct methods for detecting the starter armature 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 there is no abnormal temperature rise in the armature body. 2. Use a professional testing instrument to check its internal circuit to ensure that its resistance value has not changed, the insulation is not damaged, the brush bristles are not shortened, the contact surface of the carbon brush is not discolored, and the armature structure is not deformed. 3. Based on the test results, if problems are found with the starter armature, a new armature should be replaced promptly to ensure that the car can start normally, avoid engine damage, and prevent unnecessary repair costs. II. Starter armature maintenance 1. Regularly check the starter armature, especially after the car has been parked for a long time. Check the armature status promptly, and replace it with a new one if there are any abnormalities. 2. When the car is running, regularly check the engine

Get to know brushless DC motor stators and rotors in one minute

The stator and rotor of a brushless motor are components of the motor. The two components can coordinate with each other through the action of the magnetic coil to convert electromagnetic energy information into mechanical energy. Simply put, the stator and rotor of a brushless motor are the rotating parts of the motor. Brushless DC motors use semiconductor switching devices to achieve electronic commutation, i.e., electronic switching devices replace traditional contact commutators and brushes. They have advantages such as high reliability, no commutation sparks, and low mechanical noise, and are widely used in high-end tape recorders, video recorders, electronic instruments, and automated office equipment. A brushless DC motor consists of a permanent magnet rotor, a multi-pole winding stator, and a position sensor. The position sensor detects the change in rotor position and switches the current in the stator windings in a certain order (i.e., it detects the position of the rotor magnetic pole relative to the stator windings and generates a position sensing signal at a specific position. After processing by the signal conversion circuit, it controls the power switching circuit and switches the winding current according to a certain logical relationship). The working voltage of the stator winding is provided by the electronic switching circuit controlled by the position sensor output. There are three types of brushless motor stator and rotor position sensors: photoelectric, magnetoresistive, and electromagnetic. In brushless DC motors using magnetoresistive position sensors, the magnetoresistive sensor components (

How to check the condition of a brushless motor stator and rotor?

The stator and rotor of a brushless motor are important components of motors such as generators and starters. The stator is an important part of the motor. The stator and rotor of a brushless motor consist of a stator core, stator windings, and a frame. The main function of the brushless motor stator and rotor is to generate a rotating magnetic field, while the main function of the rotor is to be cut by electromagnetic lines in the rotating magnetic field to generate (output) current. The rotor is the rotating part of the motor. The motor consists of a rotor and a stator, used to achieve the conversion of electrical energy and mechanical energy, as well as mechanical energy and energy conversion devices. The motor rotor system is divided into two motor rotors and generator rotors. The function of the brushless motor stator and rotor is to rotate the drive shaft and provide electrical energy and mechanical energy conversion. The stator refers to the conductor in the magnetic field, the conductor is fixed, and the rotor refers to the electromagnetic coil, which moves relative to the conductor. This relative motion causes the magnetic lines of force to be cut, thus generating current in the stator coil. The stator and rotor of a brushless motor are made of iron cores and windings, and the windings are made of silicon steel and thick copper conductors. The conductors are insulated and coated with epoxy resin. The stator and rotor of a brushless motor are equivalent to conductors, and the rotor is equivalent to an electromagnet. After the rotor is energized, it is driven to rotate by the engine to form a rotating magnetic field model. Conversely, when the conductor cuts the rotating magnetic field, an induced electromotive force will be formed in the conductor.
