What is motor lamination? The two main mechanisms that make up the DC motor are the stator and the rotor. The annular iron core, together with the support windings and coils, forms the rotor. The iron core rotates in the magnetic field to generate voltage in the coils, which creates eddy currents. Eddy current is a magnetic loss. When a DC motor loses power due to eddy current flow, it is called eddy current loss. Several factors influence the amount of power loss attributed to eddy flow, including the thickness of the magnetic material, the frequency of the induced electromotive force, and the density of the magnetic flux. The flow of current in the material resistance will affect the way the eddy is formed. For example, as the cross-sectional area of the metal decreases, this results in less eddy current. Therefore, the material must be kept thinner to minimize the cross-sectional area to reduce the amount of eddies and losses.

Explanation of motor | Disc permanent magnet DC motor The axial size of the disk type permanent magnet motor is small and the shape is like a disk. Generally, the direction of the air gap magnetic field between the stator and the rotor of the motor is the meridional direction, while the direction of the air gap magnetic field of the disc motor is the axial direction. Except the direction of the magnetic field is different, the working principle is the same as that of the ordinary motor. The following describes the structure of a disk-type permanent magnet DC motor,

Advantages and disadvantages of brushless dc motor 1、Advantages of Brushless DC motor Brushless DC motors have many advantages our the traditional brushed DC motors. Few of the advantages are discussed below in detail 2、Disadvantages of Brushless DC motor Just like in all the other devices, brushless DC motors also have few shortcomings as compared to other motors. As brushless DC motor outperforms brushed DC motor in many cases, however, brushless DC motor also has few shortcomings which are discussed below:

The brushless DC motor consists of a motor body and a driver, and is a typical mechatronic product. Because the brushless DC motor operates in a self-controlled manner, it will not add a starting winding to the rotor like a synchronous motor with heavy-load starting under variable frequency speed re
