Technical Problem
[0002]现有技术中，当电机进行轻量化设计，使端盖采用密度更低的材料时，会导致电机定子铁芯三阶固频下降，产生与电机转子共振的情况，导致共振噪声，影响电机结构的稳定性
Benefits of technology
[0021]本实用新型的技术方案通过设置电机端盖包括端盖本体和端盖加强结构，设置端盖加强结构包括第一加强部和第二加强部，并将第二加强部设置于端盖本体的端盖固定部，将第一加强部设置为连接第二加强部和轴承安装部，使得该电机端盖可通过第一加强部增加端盖固定部的结构强度，在该电机端盖安装时可确保电机端盖与电机壳体连接部位的整体刚度，同时可通过第一加强部连接轴承安装部和第二加强部，使轴承安装部与端盖固定部之间形成刚性连接，并可通过第一加强部连接第二加强部来提高第一加强部靠近端盖固定部一侧抵抗弯曲变形的能力，进一步提升轴承安装部与端盖固定部之间的连接刚性，确保电机端盖具有足够的结构刚性，在将电机端盖安装至电机时，保证电机定子铁芯三阶固频大于电机的十倍转频，避免发生共振导致电机结构不稳定以及出现共振噪声。
