第四,发热带来的影响
电机发热虽然一般不会影响电机的寿命,对大多数客户来说没必要理会。但是,严重的发热会带来一些负面影响。如电机内部各部分热膨胀系数不同导致结构应力的变化和内部气隙的微小变化,会影响电机的动态响应,高速会容易失步。又如有些场合不允许电机的过度发热,如器械和高精度的测试设备等。因此对电机的发热应当进行必要的控制。
最后,减少电机的发热
减少发热,就是减少铜损和铁损。 减少铜损有两个方向,减少电阻和电流,这就要求在选型时尽量选择电阻小和额定电流小的电机,对两相电机,能用串联的电机就不用并联电机。但是这往往与力矩和高速的要求相抵触。对于已经选定的电机,则应充分利用驱动器的自动半流控制功能和脱机功能,前者在电机处于静态时自动减少电流,后者干脆将电流切断。另外,细分驱动器由于电流波形接近正弦,谐波少,电机发热也会较少。 减少铁损的办法不多,电压等级与之有关,高压驱动的电机虽然会带来高速特性的提升,但也带来发热的增加。所以应当选择合适的驱动电压等级,兼顾高速性,平稳性和发热,噪音等指标。

误解二:不锈钢没有磁性,有磁性的就不是不锈钢在日常生活中,有很多对不锈钢一知半解的人是通过有无磁性来判断不锈钢的,没有磁性的就是不锈钢,有磁性的则不是不锈钢,是不锈铁。比如我们去超市购买不锈钢物品时,超市的售货员可能会告诉你同样的识别方法,甚至还会拿一块磁铁出来,让你亲目试一试。其实,这是因为对不锈钢概念不清而产生的又一种误解。从金属学角度来看,钢和铁仅仅在于碳含量的区别,和磁性无关。事实上,常见不锈钢按金相组织特点分类,主要可分为奥氏体不锈钢马氏体不锈钢和铁素体不锈钢三类。

对于汽车发动机托架、散热器支架等典型零件,液压成形件比冲压件减轻2%~4%;对于空心阶梯轴类零件,可以减轻4%~5%的重量。减少零件和模具数量,降低模具费用。液压成形件通常只需要1套模具,而冲压件大多需要多套模具。液压成形的发动机托架零件由6个减少到1个,散热器支架零件由17个减少到1个。可减少后续机械加工和组装的焊接量。以散热器支架为例,散热面积增加43%,焊点由174个减少到2个,工序由13道减少到6道,生产率提高66%。
