电动类器具铭牌上的转速是指空载转速还是负载转速?标准里面有没有规定?还是设计工程师自己定的:即设计工程师既可以定空载转速又可以定负载转速?

假若是负载转速的话,那就难说了,因为负载有大小,转速也就差很远的。那这样的话,标转速就觉得没有参考的价值了

我们测量电动工具的转速时都是测量的空载转速

对的,是电动工具,需要标示空载转速的! [s:83] [s:83] 昨天刚铡查了标准资料的.
8.1 Tools shall be marked with:
– the year of manufacture.
– rated voltage(s) or rated voltage range(s), in volts. Tools for star-delta connection shall be
clearly marked with the two rated voltages (for example 230 Δ/ 400 Y);
– symbol for nature of supply, unless the rated frequency is marked. The symbol for nature
of supply shall be placed next to the marking for rated voltage;9 ]# A; o4 G* c/ B1 _& }4 ]
– rated input, in watts or rated current, in amperes. The rated input or current to be marked
on the tool is the total maximum input or current that can be on circuit at the same time. If
a tool has alternative components which can be selected by a control device, the rated
input or rated current is that corresponding to the highest loading possible;, } | C5 u; D) D. V
– name or trade mark or identification mark and address of the manufacturer or any other
agent responsible for placing the tool on the market;' K; ^1 l! {. a: g8 v: r
– model or type reference;
– symbol for class II construction, for class II tools only;
– IP number according to degree of protection against ingress of water other than IPX0. If
the first numeral for the IP numbering is omitted, the omitted numeral shall be replaced by
the letter X, for example IPX5;
– “WARNING – To reduce the risk of injury, user must read instruction manual” or the sign+ @" k" n6 V' o

If used, the statement shall be verbatim except the term “operator’s manual” or “user
guide” may be used for the term “instruction manual”;
Additional markings are allowed, provided they do not give rise to misunderstanding.
