1. EC Fan Introduction
EC(Electronically Commutation) motors, as built-in DC inverter driver three phase AC external rotor permanent magnet synchronous motors, its efficiency and low noise is considered to be ultimate fan energy technologies.
2. Core Technology Of EC Fan Controller
2.1. Sensorless vector control software
2.2. High-performance power electronic circuits
2.3. Security and reliability design(Standards, Certification)
2.4. Embedded design
Ventilation system in houses and buildings
Air-conditioning system in busses and yachts
FFU(Fan Filter Unit)and clean room system
EC fans includes AC input driven brushless DC fan with integrated design of AC-DC transformation circuit, the PFC circuit, the BLDC drive circuit, interface circuit. Due to the internal integration of the AC-DC converter circuit, the consumption of power will be reduced to facilitate the design and application of the overall power system in customer.
Brushless DC external rotor motor belongs to non-mechanical brush(commutator)DC motor which enforces the winding current commutation through electronic commutator (position sensing, non-position sensing),achieve the speed control function with PAM or PWM control
FAQ
1. Can we buy a sample for testing?
Sure, you are welcomed to buy a sample before mass order.
2. if the fans doesn't work well, what shall I do ?
If happens within one year, we will take in charge of the maintenance, or send you a new machine freely.
If after one year, we will supply you the right parts to replace at low price.
