1.  An Overview of EC Motor

1) About EC Motor

Nowadays, energy saving environmental protecting is one of the world's topic. It is not only the society responsibility of each enterprise, but also the necessary choice with the raising of the cost of energy and illegal environment. It will be a good choice to use the EC motor in reducing energy consumption.

2) Compare shaded pole motor with EC motor

As we know, the efficiency of shaded pole motor is in the order of 18%, which meanc that 82%of their energy consumption is transferred as waste heat and pollutions to the environment. The efficiency of the EC Motor, however, can be used in the order of 65% even more. It is the EC Motor, can reduce energy consumption and saving the demand charge.

3) Advantage

Take the motor with 12 Watt for example, the input power of shaded pole motor is 67 Watt, but EC Motor is only 18 Watt. So, by using EC Motor, we can save about 1.176 KWH per day, 429KWH per year. It means that the fee of saving electricity is much higher than the cost of purchasing EC Motor.

In the meanwhile, EC motor is also an environmental protector. For example, a typical supermarket in Europe HAS ABOUT 200 PCS shaded pole motor working in commercial refrigeration and freezers per day, EC motor instead can reduce about 230 tons carbon emissions over a five tear period, making contribution to the world of environment.

4) Suggestion

For appliance manufacturers, EC motor can improve the efficiency level and achieve the environment policy requirements of governments, also can gain a good price. Using EC Motors becomes a necessary tendency in feature days. It is good for enterprises to gain the top advantage in the market by early using EC Motor.
