LCPM series motor is a totally enclosed， external fan cooled permanent magnet synchronous motor. Based on our own independent research and development， it’s with characteristic of small size， light weight， high efficiency， strong overload capacity， smooth operation and simple maintenance. The mounting method conforms to the IEC standard and DIN standard with IC416 cooling method and S1 continuous working duty. This series of motor is super energy saving， the efficiency of its rated load accords with GB 30253-2013 standard of variable frequency drive permanent magnet motor energy efficiency. The average efficiency of the whole series is 2.5% higher than IE4 standard. Another advantage of LCPM motor is that， it can keep high efficiency and energy saving effect at the whole load range of 20%~100%， which is difficult for ordinary three-phase asynchronous motor. The energy saving effect is much more obvious to the equipments need to work at non-rated load.
