Ecm Fan Control Diagram. 20 30a motor control relay. Engine control module ecm.
The closer the energy ratings per. The microprocessor is the brains of the motor. The variable speed motor control is.
The architecture of an ecm motor is structurally complicated since its stator comprises multiple windings and involves precise timing from some control module to rotate the rotor.
On the other hand although this complexity allows for greater performance less noise and improved operating characteristics maintenance on an ec motor takes longer and is more costly. The ecms shown in figure 1 on the previous page are actually built as two separate components. Last edited by hsv gts 300. Ecm motors overview with the new fer fan energy rating law that is now in place we strongly encourage getting familiar with the ecm motor.
