EC 后倾离心风机产品概述:

EC(Electronically Commutation: 电子换向)电机为内置直流变频驱动器的三相交流永磁同步外转子电机，因其高效低噪且兼具可调速、可测速、可告警、可远程监控等特点，被认为是当下最为节能的成熟先进风机技术。

The EC (Electronically Commutation) motor is a three-phase AC permanent magnet synchronous external rotor motor with a built-in DC variable frequency drive. Because of its high eficiency and low noise, it has the char.acteristics of adjustable speed, speed measurement, alarm, and remote monitoring, lt is consid.ered to be the most energy-saving and mature advanced fan technology.
