Technical Notes
Changing out from GE 2.3 to Nidec PerfectSpeed DC
Motors in the field The
Krueger
family of Fan
Filter Units has previously used the GE 2.3 motor
that was purchased by Regal Beloit. The older models
have GE 2.3 motors that have become obsolete
and are replaced with the new Regal Beloit model
EON. The EON motor is currently being evaluated and
you will be receiving a new manufactured motor
named
Nidec PerfectSpeed.
When you order a replacement motor they will be a
form and fit replacement, except for the cable that
connects to the control board and the motor. The new Nidec
motor will require you to replace the cable. The old
cable was a sixteen pin connector while the new motor
cable will have a four pin connector as shown in the photo to
the right.
Please use the new cable with the new four pin connector
to connect your new motor. The cable number will be
determined by the build style of your unit.
