What’s EC Motor

EC fan refers to the centrifugal fan using digital brushless DC external rotor motor or the centrifugal fan using EC motor

EC (Electrical Commutation) motor power supply for DC power supply, built-in DC converter AC (through six inverter modules), rotor position feedback, three-phase AC, permanent magnet, synchronous motor. (DC brushless is only the quality of the power supply and the appearance of the motor, not the essence of the motor, EC motor is essentially a three-phase AC permanent magnet synchronous motor

Advantages of EC Motor

high efficiency factor

low energy consumption

integrated monitoring function

easy installation and connection

expanded functionality (pressure control and many more)

compact construction

EC motors are the future of the ventilation industry due to their excellent controllability, improved efficiency and longer useful life.
