Electronic commutation motor

ECM motor in forced air furnace and in order to save electricity of the HVAC system is used more and more,because of induction motor sales the HVAC system of fan running for a long time in the daytime.In the cost efficiency of the HVAC system with ECM motor is still questionable,the cost of the repair this motor is www.facebook.com/guohong.trading almost equal to or even more than saving it.Other single-phase capacitor motor general principal deputy for the parallel operation,the main current in our actual use load range of 90 degrees or so, You can get the best performance;And series connection generally appear in one pole winding speed regulating pole change motor,when in actual use NaZhu vice around the load ac alternators 220v range Consistent set of basic Angle,unable to form a circular magnetic field.
