Heat Pumps Dc Fan Motor With Km140c-3 For Water Chillers,Cooling
1． 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.
2． 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
