高速驱动电机系统技术挑战

当前汽车电驱动用高速永磁同步电机已经取得了较大的进展，如一汽、比亚迪、上汽、特斯拉、小鹏、蔚来等主机厂都有高速电机的研发应用，但仍面临性能、材料、结构设计及生产方面的技术挑战。

3.1 高功率密度挑战

功率密度可以通过提升功率而得到提高，根据转矩与功率计算公式可知，功率提升有2种途径：

（1）提高扭矩；

（2）提高转速。

提高电机功率密度需要应对的挑战包括：

（1）提高转矩会导致过载电流加大，造成发热量高，对电机散热造成较大压力；

（2）提高转速时会导致电机铁耗过大，需采用、低损耗硅钢片，因此成本较高。

3.2 永磁材料挑战

永磁材料也是制约永磁同步电机性能提升的重要因素，目前常用的永磁材料为钕铁硼，主要表现为高剩磁密度、高矫顽力、高磁能积和线性退磁曲线优异的磁性能。目前，钕铁硼满足新能源汽车对电机体积小、高功率密度、率和高速化的需求，但是钕铁硼温度稳定性差，具有不可逆损失和温度系数较高和高温下磁性能顺势严重的缺点，从而影响电机性能进一步提升。新型永磁材料的研发和应用也将为电机设计提出了新挑战，成功应对挑战将为高速电机的研发注入新的动力。
