Original Style Gear Drive Conveyor
Motor Replacement and Version Compatability ®Middleby PS350, PS360 and PS570 Pizza Ovens

or ® Middleby part# 27384-0008, 46603

Baldor is the most common motor found in these ovens. The
gear box ratio was 1400:1. Baldor was the original style
motor for PS350, PS360 PS360WB PS360WB70, PS360EWB and early PS570
ovens. Manufactured for ®Middleby by Baldor for ~ 20 years and
found in almost every PS360 oven. Manufactured for CTI by Baldor
from 2002 to 2019 when Baldor stopped making gear motors. This
motor was identified
by the Baldor name/logo and uses the external speed sensor clamped
to the outside of the motor. It is gray in color and has a larger
diameter ( 3.3" OD ) motor. The nameplate gear ratio is 1400:1 and
the available continuous horsepower is 1/8 HP. The larger
brushes allow for years of service without maintenance. The gearbox
is made through a ( higher investment ) die cast construction. The
gearbox uses a more expensive synthetic lubricant, dedicated seals
and Teflon coatings, all designed to improve the gearbox
efficiency. The CTI speed
control also has a motor efficiency test mode that is a built-in
function of the speed controller.
No additional parts required to replace Original Baldor gear motor
with CTI or Bodine 1400:1 motor on right:

If your existing gear motor is a Bodine :

This was the second generation motor for PS350, PS360 PS360WB
PS360WB70, PS360EWB and early PS570 ovens. This motor was
manufactured for ®Middleby by Bodine for roughly 5 years . The 47796
motor is identified by a silver cap covering the end of the motor
that is oposite the gearbox. The motor portion of this gearmotor is
also much smaller 2.4"OD with a typical horsepower rating of 1/22
HP. The nameplate gearbox reduction ratio is still 1400:1 (so all
oven sprockets are still the same). The gearbox on this motor is a
little more square due to the casting method chosen by the
manufacturer. The internal gearing consists of a dual worm and
matching bronze gears to provide the 1400:1 reduction in speed and is
similar to the Baldor worm gearing. There are 2 sets of wires
exiting the motor. The second set of wires originates from the
internal speed sensor.

Description:
If you are changing from a Bodine motor ( with the built-in speed sensor), then you will also need to order our external speed sensor
(CTI-M-H1).
CTI-M-27384-0008
If your existing motor is a textured graycolor and the nameplate mfg is Groschopp:

This motor is identifiable by the printing on
the nameplate. You will notice a printed gear ratio spec of 80:1
(Ratio: 80:1) and the printed name brand of Groschopp. This motor was
part of a conversion kit designed to use one motor and a variety of
gears/sprockets and hardware to replace many of the older oven motors.
This kit came out ~ 3 to 4 years ago and is less common, when
compared to the Baldor gear motor.
To use the CTI gear motor, you will add the hall effect speed sensor
(part number CTI-M-H1), 9 tooth sprocket (part number CTI-M-SP9), and
15 tooth sprocket (part number CTI-M-SP15). In effect, you are taking
the oven back to its original gear motor. The combined cost of the two
sprockets is $19. You will need to call for information on the speed
sensor. If the motor was a recent retrofit, then the user may still
have the old sprockets and sensor.
Parts required to replace gear motor shown on left with motor on right:
• Hall Speed Sensor: CTI-M-H1
• Motor Sprocket: CTI-M-SP15
• Conveyor Sprocket: CTI-M-SP9
Note: If the motor on the left was installed as a retrofit,
then the oven owner may still have the parts from the old motor.
