How are ECM motors "energy saving"?
ECM motors are very high efficiency (65% to 80%) electric motors and maintain a high efficiency level at part speed. This means that in most cases they use from less than one third to one half of the electricity used by shaded pole or PSC induction motors used in the ventilation and refrigeration industries, which in turn translates into lower operating costs and short payback periods.
The huge energy savings provided by GP's ECM motors directly translate into large carbon emissions savings. In this way, switching to ECM motors allows our customers to dramatically reduce the air pollution (CO2) generated by their applications.
Also, GP energy saving motors are designed using less raw materials than traditional inefficient motors and other electronically commutated motors. In particular, GP EC motors use 35% less copper and 75% less steel than traditional induction motors, a dramatic reduction in the motor components' environmental impact.
