Create better products with the ECM 142.
With features unavailable with
conventional induction motors, the ECM
technology gives product designers and
engineers an extremely versatile tool for
improving HVAC-system performance and
differentiating products in indoor or
outdoor applications. Here are some
examples of the system benefits made
possible by the ECM 142 motor: precise
speed and torque control, lower set-up and
inventory costs, and quieter, more
economical operation.
Programmable Controls.
Just one motor can optimize your system
performance and minimize your
inventory. Programming options for the
ECM 142 include: rotation direction,
speed and torque, and many other
functions––all conveniently programmed
into the motor by GE at the factory. As a
result, programmability means lower
inventory because one motor can serve
many applications.
Ultra-high efficiency.
At full load the ECM 142 is 20% more
efficient than a standard induction
motor. In addition, its permanent-
magnet, DC design allows it to maintain
its efficiency over its wide speed range.
Resilient electronics.
Line transients from lightning strikes or
corrupt utility power can cause damage or a
temporary interruption of power to any
electrical appliance. The ECM 142 Series
comes standard with robust electronics that
allow the motor to operate trouble-free in
the event of power irregularities without
external protection. In addition, short
power-line interruptions or under-voltage
conditions do not affect the operation of
the ECM 142.
Wide range of applications.
The ECM motor has given product
designers and engineers a tool for greatly
expanding the capability of air-moving
appliances. Here are a number of possible
applications: outdoor condenser fans;
single-stage, two-stage and variable-
capacity furnaces ; air handlers; energy-
recovery ventilators; powered filter units;
unit ventilators; geothermal heat-pump
systems; and commercial fan-powered
terminal units.
Moisture-resistant design.
The ECM 142 addresses the most common
problem today in HVAC systems––
moisture. GE encapsulates the motor’s
sensitive controls to prevent water from
reaching its electronic components. In fact,
the ECM 142 stands up to more than 600
hours of ASTM-B117 salt-spray testing.
Easy installation and service.
The ECM 142 is designed to be easy to
install, troubleshoot and service. There is
no need to go to the motor for set up. In
fact, there are no dip switches or
adjustment terminals on the ECM 142.
The system manufacturer can locate all
connections required for set up in any
convenient location. When it comes to
service, the 142 is designed so its electronic
controller can be replaced without
removing the motor from the blower
mounting, which greatly reduces service
time and cost.
