In 1987 General Electric introduced ECM technology to the
residential HVAC industry. This technology is predominantly used
in variable speed indoor blower motors, constant speed induced
draft motors and condensing fan motors. These innovative motors
changed the industry by providing unmatched efciency as well
as comfort options not possible with PSC induction motors.
In 2004 the Regal Beloit Corporation acquired General Electric’s
Commercial and HVACR Motors and Capacitors businesses with
the right to use the GE brand through 2009. These divisions were
named GE ECM by Regal Beloit, GE Commercial Motors by Regal
Beloit and GE Capacitors by Regal Beloit. In 2009, Regal Beloit
announced the rebranding of those GE branded businesses
under the name Genteq, for markets that include residential and
commercial HVAC equipment and electrical applications that
utilize capacitors. With this rebranding, the Genteq logo took the
place of GE ECM, GE Commercial Motors and GE Capacitors
logos on all branded products, sales and marketing materials,
Web sites, communications documents, signage and other related
items. This rebranding reects the company’s reputation for
innovation and speaks to the future.

Mounting
The frame size of the Evergreen CM motor is NEMA 48 (5.6” Diameter). This
is the most common frame size for indoor blower motors. The Evergreen
CM requires a belly band style mounting bracket.
- If the motor being replaced has the same frame size and a belly band
style mount, it should work on the Evergreen CM.
- If the motor mount is welded to the motor, bolted directly to the motor,
or attaches to the bearing assembly on the motor, it will not work on
the Evergreen CM.
- Torsion ex belly band mounts can be used on the 1/3 and 1/2 HP
motors. These mounts should not be used on the 3/4 or 1 HP motor due
to noise and reliability concerns.
- Universal belly band motor mounts in multiple sizes are available
through your local distributor. See page 4 for mounting options.
- If the mounting bracket must be replaced, selecting one with the
same mounting pattern on the blower housing will save drilling new
holes in the blower section.
- The belly band must t the new motor properly. It should be tight
enough to prevent the motor from shifting on start-up and located
according to the diagram below.
Always disconnect the main power from the unit being serviced before
disconnecting any wiring or removing any components. It is also a good
practice to conrm that the power is off with a meter.
EvergreenCM ManPROOF 100713_Fnl.indd 3 7/2/14 9:15 AM
Mounting (CONT’D)
If a new motor mount is required
and the legs do not line up with
the original holes in the blower
housing, it is required to use a
bolt with either a lock washer
and nut or a locking nut through
the drilled hole(s). Self tapping
or sheet metal screws are not
sufcient for a long term installation
when a new hole is drilled through the thin wall of the blower housing.
When positioning the legs of the bellyband on the motor, make sure that
once the motor is mounted into the blower section, the wires exit the bottom
of the motor as installed in the air handler. This will insure that a proper drip
loop can be made with the signal and power lines.

Electrical Connections
The unique design of the Evergreen CM allows for multiple speed operation
using either 24VAC (18VDC) discrete inputs or variable speed, torque control
using a PWM controller.
Unlike a PSC motor, the high voltage power terminals (L) and (N) are
connected to a continuous, un-switched power supply.
The motor on/off operation and speed/torque selections are connected
using the low voltage (C) and (1-5) terminals.
- With 24VAC, the Evergreen CM provides 5 speed operation using
terminals (C) and (1-5).
- With 18VDC, the Evergreen CM provides 3 speed operation using
terminals (C), (1), (3), and (5)
- With the addition of a PWM controller, the Evergreen CM provides variable
speed torque control using terminals (C) and (1).
The Evergreen CM will automatically recognize the connected low voltage
input and operate accordingly. Each motor provides all three low voltage
control operations.
Detailed wiring for the High Voltage Power Connections and each unique
Low Voltage Signal Connections are covered in the following sections.

Electrical Connections
High Voltage Power Connections
The Evergreen CM is designed for continuous un-switched connection to
its rated high voltage power supply. Motor operation is controlled by low
voltage signal inputs.
Always conrm the rating on the motor matches the power supply of the
system it is applied to and/or the motor it is replacing.
If a door safety switch is present, wire after the switch so power will be
disconnected when the door is removed for maintenance or service.
1. Using 3/16” Female Quick Connect Terminals and 18 AWG wire, connect
the (L) and (N) terminals on the motor to any un-switched line voltage L1
and L2, Nameplate Voltage power supply.
2. Using a 3/16” Female Quick Connect Terminal and 18 AWG wire,
connect the (G) terminal on the motor to the system ground.
Always disconnect the main power from the unit being serviced before
making any wiring connections to the Evergreen CM. It is also a good
practice to conrm that the power is off with a meter.

Electrical Connections
Low Voltage Signal Connections
- (24VAC) Discrete Speed Operation
The Evergreen CM has 5 available speeds using 24VAC control inputs.
The inputs of the Evergreen can connect directly to the 24VAC thermostat
terminal strip for each demand, a 24VAC signal output from the HVAC
systems relays or control board.
1. Using a 1/4” Female Quick Connect Terminal and 22-18 AWG wire,
connect the (C) Common terminal on the motor to the 24VAC common
(C) thermostat terminal or 24VAC common side of the transformer on the
HVAC System. Make sure that this line is not connected to the side of the
transformer connected to the thermostat 24VAC (R). If it is connected to
the (R) high side of the transformer, the motor will not operate.
2. Select operating speeds by using 1/4” Female Quick Connect Terminal(s)
and 22-18 AWG wire to connect terminals (speeds) 1-5 to any 24VAC
thermostat demand or 24VAC HVAC system relay or control board
output.
DO NOT connect the Low Voltage SIGNAL (speed) connections to the
existing PSC motor connections on the HVAC system. Any voltage above
30VAC connected to these terminals will cause permanent damage to
the motor.
