摘要：正弦波驱动的永磁无刷直流电机对齿槽转矩和反电势谐波含量通常有较高的要求，可采用多种方式进行削弱。本文针对批量生产要求，定子采用直槽叠装工艺，转子采用“一”字型内嵌结构，通过采取不等气隙的设计，达到降低齿槽转矩和反电势谐波含量的目的，最大程度节约材料成本。描述了一款1500W，10极12槽内嵌式永磁无刷直流电机优化设计过程。通过对样机测试表明，电机的齿槽转矩和反电势谐波含量较低，达到设计要求。
关键词：内嵌式；不等气隙；谐波；齿槽转矩
Abstract: Sine wave driven permanent magnet brushless DC motor for the cogging torque and back EMF harmonic content usually have higher requirements, can be used in a variety of ways to weaken. Mass production requirements, the author of this paper, the stator adopted straight flute fold in process, the rotor structure of "one" word embedded, by taking the design of the air gap, to reduce the cogging torque and back EMF harmonic content, the purpose of saving the cost of materials to the greatest extent. Described a 1500 W, 10 Pole 12 slots embedded permanent magnet brushless DC motor optimization design process. Through the prototype test show that the motor of the cogging torque and back emf harmonic content is low, to meet the design requirements.
Key words: embedded；unequal air gap；harmonic；cogging torque
