Anelectronically commutated (EC) fan设计提供了综合效益AC和DC Fans。EC风扇的电源来自无刷直流电动机，但它提供了通过印刷电路板的AC感应风扇在风扇转子上进行控制。电子换向风扇的DC电机具有内置变速控制的优点。
一个交流电源战俘ers the EC fan, but the on-board electronics convert the power to DC before reaching the motor. The secondary magnetic field generated by the permanent magnets makes EC fan motors considerably more efficient than AC induction motors.
This blog post will discuss the four primary benefits offered by electronically commutated fans.
Increased Efficiency
EC风扇电机的高能量效率来自减少能耗。即使在部分速度下，EC风扇电机也继续保持高效率。EC风扇电动机中的二次磁场来自转子内的永磁体。这使得EC电动机能够节省能量，这些能量将产生辅助磁场，如铜绕组在交流感应电动机中实现。
While the EC motor is running, it constantly monitors the electricity powering the fan and makes continuous adjustments to keep fan power optimized. The fan maintains efficiency within a range of speeds rather than a single specified speed. The level of control is similar to the frequency controller used inAC motors, but EC motors can remain efficient at any speed within its design capabilities. These factors help EC fan motors achieve as much as 30% more energy efficiency than AC fan motors.
更多控制
EC fan motors use multiple methods of control to deliver better efficiency and simplify control of small or large-scale applications. EC fan motors have a printed circuit board that allows precision control through a computer application. Administrators have control of fan speed, torque, and ramp-up time through a central location, and MODBUS-network protocol for scalable automation of fan controls and simplified 0-10V controllers are also available. The advanced control granted to operators allows for optimum efficiency in a variety of applications, making the fan up to 90% more efficient.
更长的寿命
Industries and applications that require reliability and longevity can rely on EC fans for a longer lifespan than AC fans with similar capabilities. AC fan motors have carbon brushes that eventually wear out, but the lack of carbon brushes on the EC fan motor eliminates the risk of wear.
Low operating temperatures are another factor of EC motor longevity. Electronically commutated fan motors maintain a lower temperature compared to similar AC fans, decreasing heat-related failure. More reliable operation and a longer service life can offset the higher upfront cost of switching to EC fans by reducing the need for long-term maintenance, repair, and replacement costs.
Compact & Versatile
EC fans have a space-saving design, allowing them to operate at a high capacity at a smaller physical size. The smaller size is largely due to the external rotor. The weight of an EC motor is four times less than an AC motor with similar capabilities, and the less bulky design delivers better airflow. EC motors are a practical solution in environments where space is of concern.
