The EC Motor is running on a DC voltage, but with 115V or 230Volts AC supply. The effect is minimum power consumption, infinite control possibilities (through 0-10V signal or PWM), but with a standard 230V 50/60Hz supply. Unlike the DC Motor which requires a separate motor driver. The electronically commutated motor can be offered with a number of options, such as hall effect or alarm output. The EC programming is also suitable for constant speed or constant pressure control, etc.
Higher efficiency
The major advantage of EC motors over their AC counterparts is far higher efficiency, Programming is also suitable for constant speed or constant pressure control. Speed control is simple, and results in impressive energy saving performance.
By using the temperature controller on an air conditioning systemto reduce the speed of the EC motor during periods of reduced cooling demand, you can cut energy wastage dramatically. For example, an annual fan energy consumption of 620 kWh can be reduced to 140 kWh using speed control.
