Then and Now – The History of the GE ECM™
1987
ECM 1.0
Hardware Programmable
1992
ECM 2.0
Complete Motor and Control Design
o
Torque Calibrated machine
o
Refined airflow regulation algorithm
“motor is the airflow sensor”
o
Late point product identification – software
programmable, program could be changed
o
Often called the ICM-2
(Integrated Control Module)
o
No Longer in Production
1998
ECM 2.3
Response to Reliability Improvement
This is the current production blower motor for most
OEM’s using variable speed.
o
Control Electronics and packaging redesign
o
Electronics encapsulated for moisture resistance
o
New motor controller “ASIC”
o
Improved performance and features
o
Sometimes called the ICM-2+
(Integrated Control Module)
o
Currently in Production
2002
ECM 2.5
Digital Serial Communication
o
Enables plug & play HVAC systems
o
Fewer replacement part numbers
o
More accurate operation and fault reporting
o
Currently in Production
Once the program was installed in the motor control it
could not be changed.
o
Basic constant airflow Algorithm
o
Often Called the ICM-1
(Integrated Control Module)
o
No Longer in Production
