摘要:

针对新型软磁材料非晶合金在电机中的应用对电机性能影响的问题,首先测试对比分析了新型软磁材料与普通硅钢材料损耗等性能,验证了其应用于高效电机的可行性,然后对同结构的非晶合金电机和传统硅钢电机进行了初步对比分析,研究表明非晶合金电机铁耗仅为传统硅钢的10%左右,但其铜耗升高28%左右,致使电机效率提升效果不明显。最后针对非晶合金电机铜耗产生机理进行了分析,根据电机铜耗增加的原因,对电机结构有针对性地进行调整优化。对优化前后电机铜耗、铁耗以及效率等电机性能参数进行对比分析,研究结果表明优化后电机本体效率可达到98.14%,相对优化前提升1.012%,比传统硅钢电机效率提高1.54%。

Abstract:

Aiming at the influence of the application of new soft magnetic material amorphous alloy in motor on the performance of motor, firstly, the loss and other properties of the new soft magnetic material and ordinary silicon steel are tested and compared, and the feasibility of its application in high-efficiency motor is verified. Then the comparative analysis of the same structure two motors that the amorphous alloy motors and traditional silicon steel motors is conducted. It shows that the core loss of amorphous alloy motor is only about 10% of that of traditional silicon steel, but its copper loss increases by about 28%, so the effect of improving motor efficiency is not obvious. Finally, the reasons for the increase of copper loss of amorphous alloy motor are analyzed. According to the reasons for the increase of copper loss, the motor structure is adjusted and optimized. The performance parameters of the motor such as copper loss, core loss and efficiency before and after optimization are compared and analyzed. The research results show that the efficiency of the motor body after optimization can reach 98.14%, which is 1.012% higher than that before optimization, and 1.54% higher than that of the traditional silicon steel motor.

Key words: New soft magnetic motor, motor optimization, copper loss of motor, high efficiency motor, permanent magnet motor
