在机床制造业中,多速电动机的使用不断增加,因为在机床电力驱动装置中,用多速电动机代替普通单速电动机,就能够以电机的调速,部分或全部地代替机床的机械调速,而且在许多情况下,提高了机床的工艺和运转的质量,同时减少了制造机床的劳动量。 用多速电动机代替单速电动机的机床电 In the machine tool manufacturing industry, the use of multi-speed motors is constantly increasing, because multi-speed motors instead of ordinary single-speed motors are used in the machine tool’s electric drive to replace part or all of the machine’s mechanical speed control , And in many cases improves the quality of the machine’s processes and operations while reducing the amount of labor required to manufacture the machine. Multi-speed motor instead of single-speed motor of the machine
