能源短缺和全球变暖是我们面临的巨大挑战，在电机中使用磁性槽楔可以提高效率、降低温升、减小震动和噪声。
    Energy shortages and global warming are big challenges, and using magnetic wedges in motors can improve efficiency, reduce temperature rise, and reduce vibration and noise.

    磁性槽楔是一种电机上使用的导磁槽楔。磁性板槽楔是在树脂中均匀加入还原性铁粉，用无碱玻纤布复合增强热压成导磁板；铁粉粒度为100－400目。磁性槽楔有以下几个特点：一是节能，电机采用磁性槽楔减少了励磁电流，改善功率因数，效率提高1－2%；二是延长电机寿命，电机采用磁性槽楔，可降低铁芯损耗40%以上，降低电机升温，减少电磁噪音和震动；三是降低启动转矩，由于磁性槽楔是导磁体，因此使电机的漏磁增强，启动转矩有所下降；四是安装简便，便于维修，磁性板槽楔适合于所有开口电机上使用，安装方法与竹制、环氧布板槽楔相同，修理时优于磁泥，可采取一次性整体退槽或破坏性退槽，残留物在槽中容易清理干净。

    A magnetic slot wedge is a magnetic slot wedge used on a motor. The magnetic plate slot wedge is made by adding reducing iron powder evenly into the resin and using non-alkali glass fiber cloth to reinforce the plate. The particle size of iron powder is 100-400 mesh. Magnetic slot wedge has the following characteristics: first, energy saving, the use of magnetic slot wedge motor to reduce the excitation current, improve the power factor, efficiency increased 1-2%;The second is to extend the life of the motor, the motor using magnetic slot wedge, can reduce the core loss of more than 40%, reduce the motor heating, reduce the electromagnetic noise and vibration; Three is to reduce the starting torque, because the magnetic slot wedge is a magnetic body, so that the motor magnetic leakage enhancement, starting torque is decreased; The magnetic board slot wedge is suitable for all open motors. The installation method is the same as bamboo and epoxy cloth board slot wedge. It is better than magnetic mud when repairing.
通常应用的磁性槽楔主要有模压磁性槽楔（优点：强度高，导磁强；缺点：生产效率低，价格很高）；磁性板槽楔（优点：强度高，导磁强，生产效率高，价格适中，适合批量生产；缺点：损耗大）；磁性引拔槽楔（优点：纵向强度很高，生产效率高，价格适较便宜，适合批量生产；缺点：横向强度较低，导磁率相对较低）

Magnetic slot/groove wedge mainly can be mainly divided into:

-  Press moulding magnetic groove wedge

Advantages: high strength, strong magnetic permeability;

Disadvantages: low production efficiency and high price

- Magnetic plate slot wedge

Advantages: high strength, strong magnetic conductivity, high production efficiency, moderate price, suitable for mass production;

Disadvantages: big loss;

- Pultrusion magnetic slot wedge

Advantages: high longitudinal strength, high production efficiency, cheaper price, suitable for mass production;

Disadvantages: low transverse strength, relatively low permeability

经多年使用经验及研究发现，使用磁性槽楔，卡氏系数明显降低并可以提高效率、降低温升和减少噪声。图1是文献中报道使用磁性槽楔后电机效率提高数据。横坐标是电机功率，纵坐标是电机效率的提高，从图中可以看出电机效率可以提高0.5%到1.7%，平均约1%。
    After years of experience and research, it is found that the magnetic slot wedge significantly reduces the Kapp coefficient and can improve the efficiency, reduce the temperature rise and reduce the noise. Figure 1 is the data reported in the literature on the improvement of motor efficiency after using magnetic slot wedge. The abscissa is the motor power, and the ordinate is the improvement of the motor efficiency. It can be seen from the figure that the motor efficiency can be improved by 0.5% to 1.7%, about 1% on average.
