永磁直流空心杯电机突破了传统的转子结构，采用无铁心电枢，也叫空心杯电枢。
空心杯电枢结构彻底消除了因铁心产生涡流而造成的铁耗，同时其重量和传动惯量大幅降低。从而减少了自身的机械损耗，使电机的运转特性得到了极大改善，不但具有突出的节能特点，更为重要的是具备了普通电动机所无法达到的伺服特性。
Pemanent magnetDC Coeless moto is a beak-though of taditional stuctue of oto. It adopts ionless amatue, also known as coeless amatue.
Stuctue of the coeless amatue completely eliminates the ion losses caused by the votex of ion coe. Significantly educed weight and mass inetia help in loweing the mechanical wea and geatly impove the chaacteistics of moto opeation.Not only having an outstanding enegy-saving featue, it is also equipped with sevo chaacteistics which can not be attained by odinay electic moto.
电机启动、制动迅速，响应机快。在高速运转状态下，可以方便地对转速进行灵敏的调节。
Fast stat and bake, apid eaction. In high speed opeation, moto speed can be egulated pecisely and apidly.
