Brief 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 supply, built-in DC to AC, rotor place feedback, three-part AC, everlasting magnet and synchronous motor.
Its advantages:
EC motor is a DC brushless upkeep-free motor with the constructed-in intelligent management module, with RS485 output interface, 0-10V sensor output interface, 4-20mA speed control change output interface, alarm system output interface and grasp-slave sign output interface. This product has the characteristics of high intelligence, excessive energy saving, excessive effectivity, long life, low vibration, low noise and steady operation.
Features are:
A Brushless DC motor is drastically simplified in structure because it omits the collector ring and brushes for excitation. At the identical time, not solely the manufacturability of the motor is improved, but in addition the mechanical reliability of the motor operation is vastly enhanced and the service life is extended.
At the same time, the air hole magnetic density can be vastly improved, and the motor index can achieve the perfect design, and its direct effect is to scale back the dimensions and weight of the motor. Furthermore, compared with other motors, it also has excellent management performance. This is because: firstly, the torque fixed, torque inertia ratio and power density of the motor are significantly improved as a result of excessive efficiency of everlasting magnet materials. Through cheap design, the indexes reminiscent of moment of inertia, electrical and mechanical time constants will be drastically diminished, which has been greatly improved as the primary index of servo management performance. Secondly, the design of the fashionable everlasting magnet magnetic circuit has been perfected, and the coercive drive of permanent magnet material is high, so the anti-armature response and anti-demagnetization skill of the everlasting magnet motor is enormously enhanced, and the control parameters of the motor are drastically decreased with the influence of external disturbance. Thirdly, as a result of the permanent magnet is used to exchange the electric excitation, the design of excitation winding and excitation magnetic field is lowered, so many parameters corresponding to excitation magnetic flux, excitation winding inductance and excitation current are diminished, thus directly decreasing controllable variables or parameters. Primarily based on the above factors, it may be mentioned that the everlasting magnet motor has glorious controllability.
