[IEC标准产品] 电动类器具铭牌上的转速是指空载转速吗?

电动工具一般确实是标空载转速, 但标准没有强制要求标:

如果是电动机或motor,标的是理论转速。一般鼠笼式电动机有转速差,即转子转速滞后定子内的磁场转速。电动类器械的实际空载输出转速比理论转速只差一点点。作为一个机械设计人员,电动类器具铭牌上的转速是通过其它参数决定的。如所需的整体功率,所要输出的转速。再来决定所需要电动类器械的原始输入转速。但一部机械的设计,设计人员应最关心的是电动类器械的输出功率和转矩,其次才是转速。

标准没有要求说一定要显示转速7 J: B  A9 G. `: T0 Y6 M
名牌上的转速 大部分都是标明空载转速9 C) i" c9 H- S# [

带额定负载时的额定转速.
