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。
Permanent magnetDC Coreless motor is a break-through of traditional structure of rotor. It adopts ironless armature, also known as coreless armature.
Structure of the coreless armature completely eliminates the iron losses caused by the vortex of iron core. Significantly reduced weight and mass inertia help in lowering the mechanical wear and greatly improve the characteristics of motor operation.Not only having an outstanding energy-saving feature, it is also equipped with servo characteristics which can not be attained by ordinary electric motor.
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 start and brake, rapid reaction. In high speed operation, motor speed can be regulated precisely and rapidly.
