Motor stator and rotor core is a common anti-interference component in electronic circuits, which has a good inhibitory effect on high-frequency noise. It is generally made of silicon steel sheet. Many people don't know about stator and rotor iron core. In order to let you know more about our products and increase your knowledge, I'd like to introduce you to the performance characteristics of motor stator and rotor iron core.

1、 High saturation magnetic induction intensity: it is conducive to the selection of high working magnetic induction point.

2、 Low coercivity and high initial permeability: it can reduce the action current of leakage switch.

3、 High permeability of stator and rotor iron core: greatly improve the accuracy of transformer and reduce the ratio difference.

4、 Light weight and low cost: the price is obviously better than permalloy.

5、 It has good overload resistance and good temperature stability: it can work for a long time at 55-130 ℃.

Reasons for using silicon steel sheet in motor stator core

Commonly used transformer cores are generally made of silicon steel sheets. Silicon steel is a kind of silicon steel. The reason why silicon steel is used as the iron core of transformer is that silicon steel itself is a magnetic material with strong magnetic conductivity. In the energized coil, it can produce large magnetic induction intensity, which can reduce the volume of transformer.

The actual transformer always works under AC state, and the power loss occurs not only in the resistance of the coil, but also in the iron core magnetized by AC current. Usually, the power loss in the iron core is called "iron loss". The iron loss is caused by two reasons, one is "hysteresis loss" and the other is "eddy current loss".

Hysteresis loss is the iron loss caused by the hysteresis phenomenon in the magnetization process of the iron core. The size of this loss is directly proportional to the size of the area surrounded by the hysteresis loop of the data. The hysteresis loop of silicon steel is narrow, and the hysteresis loss of transformer core made of silicon steel is small, which can greatly reduce its heating degree.
