Temporary Introduction Of EC Fan
EC fan refers to centrifugal fan with digital brushless DC outer rotor motor or centrifugal fan with EC motor. EC motor energy supply is DC power provide, constructed-in DC to AC, rotor position feedback, three-part AC, everlasting magnet and synchronous motor.


Its advantages:
EC motor is a DC brushless maintenance-free motor with the constructed-in clever control module, with RS485 output interface, 0-10V sensor output interface, 4-20mA velocity control swap output interface, alarm device output interface and grasp-slave sign output interface. This product has the characteristics of excessive intelligence, high power saving, excessive efficiency, long life, low vibration, low noise and continuous operation.


Options are:
A Brushless DC motor is enormously simplified in construction as a result of it omits the collector ring and brushes for excitation. At the identical time, not only the manufacturability of the motor is improved, but in addition the mechanical reliability of the motor operation is significantly enhanced and the service life is prolonged.

At the identical time, the air gap magnetic density might be tremendously improved, and the motor index can obtain one of the best design, and its direct effect is to reduce the scale and weight of the motor. Moreover, in contrast with different motors, it additionally has glorious control efficiency. This is because: firstly, the torque constant, torque inertia ratio and energy density of the motor are drastically improved because of the excessive performance of permanent magnet supplies. Through affordable design, the indexes akin to second of inertia, electrical and mechanical time constants could be vastly decreased, which has been significantly improved as the principle index of servo control performance. Secondly, the design of the fashionable permanent magnet magnetic circuit has been perfected, and the coercive pressure of permanent magnet materials is high, so the anti-armature response and anti-demagnetization means of the everlasting magnet motor is significantly enhanced, and the control parameters of the motor are drastically diminished with the influence of exterior disturbance. Thirdly, as a result of the everlasting magnet is used to replace the electric excitation, the design of excitation winding and excitation magnetic field is lowered, so many parameters equivalent to excitation magnetic flux, excitation winding inductance and excitation current are lowered, thus straight lowering controllable variables or parameters. Based on China ec fan , it can be mentioned that the permanent magnet motor has wonderful controllability.
