Description

汽车交流发电机中渐开线式单面倒角爪极
技术领域
    本实用新型涉及机电一体化技术领域，具体属于汽车交流发电机中渐开线式单面倒角爪极。
背景技术
汽车发电机的电磁噪音，始终是一个困扰的技术难题。由于汽车发电机工作转速、负载大小变化较大，转速在1500-18000rpm之间变化，负载也几安培到几十安培，甚至上百安培之间变化，从而造成降噪的难度较大，降低发电机的噪音、提高效率是一种发展趋势。
实用新型内容
本实用新型的目的是提供一种汽车交流发电机中渐开线式单面倒角爪极，为降低发电机的电磁噪音，采用一种渐开线式单面倒角式爪极，应用于发电机的转子，有效的降低了发电机的电磁噪音。
本实用新型的技术方案如下：
一种汽车交流发电机中渐开线式单面倒角爪极，所述的爪极的一侧设有渐开线式倒角。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
参见附图，一种汽车交流发电机中渐开线式单面倒角爪极，爪极1的一侧设有渐开线式倒角2。
在发电机转子爪极的一侧采取渐开线式倒角，缓解发电机在磁场变换时的磁力线的畸变而产生的电磁噪音。
