一般直流电机转速： 3000rpm-12000rpm
一般工作转矩不能超过堵转转矩的 1/4 至 1/3
Nominal voltage电机最大效率的电压

Bigger motors from a few tens of Watts are usually designed for 1000-2000RPM. Small motors 1-20W are 5-10,000RPM Micro-motors (under 1W) may be 15-25000 RPM Specialised motors in ultra centrifuges and dental drills - 50-100,000 RPM. Universal motors as in vacuum cleaners and electric drills (mains powered) can be 20,000 RPM.
