What Is a Motor Core?
A motor core, as the name implies, refers to the core of a motor.
The core of the motor is the iron core, which is the pathway for the magnetic flux of the motor. The core allows magnetic fields to pass through more easily than in air and is an important element in the propagation of the magnetic flux between the primary and secondary stages.
The most commonly used material for cores is electromagnetic steel sheet, but there are various other materials such as silicon steel sheet, permalloy, ferrite, and amorphous. There are also various types of cores by shape, such as sheet cores, cut cores, R-cores, and toroidal cores.
Uses of Motor Cores
Motor cores are used in the iron core of motors. It is used in the iron core of the rotor (rotor) and stator (stator) that make up the motor.
High assembly precision is required for the rotor and stator in order to achieve motor performance. Therefore, high machining accuracy is required for the motor core.
Since motors are used in a wide variety of electronic devices that are electrically and physically driven, and since motors of various sizes are used in electronic and industrial devices, motor cores used in the iron cores of motors are also used in a great many electronic devices.
Principle of Motor Cores
As the principle of motors, taking a rotating motor as an example, it can rotate with magnets and magnetic force. When a magnet is turned around a permanent magnet with a rotating shaft, the N and S poles attract and repel each other, causing the magnet with the rotating shaft to turn. If we replace this with a situation where the magnet is driven by electricity, a magnetic field is generated around the copper wire by passing an electric current through it. This becomes a rotating magnetic field, which is the same as the environment in which a magnet rotates.
By coiling the copper wire, the magnetic force is synthesized into a magnetic flux. Also, by inserting the core into the coiled copper wire, the magnetic field lines can easily pass through the core and generate a stronger magnetic force. Motor cores are used inside motors in this way.
Motor cores are processed as laminated cores, which are made by laminating plates. The processing methods for laminated cores include the caulking method, in which multiple plates are pressed together as laminated parts, the laser welding method, in which laminated parts are welded together, and the bonding method, in which laminated parts are adhered together using adhesive.
