 Gear motor for Middleby 47796

Baldor is the most common motor found in these ovens. 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 since 2002. This motor is 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 over competing brands of wormgear motors.  Our initial lab testing indicates that the Baldor is leading as the most effienceint gearmotor, of all of the gearmotors we have tested  (having a 1400:1 gear ratio).  If you service  (or own)  several brands of gearmotors, we have a very simple test that will allow a direct comparison of gearmotor efficiency. The CTI speed control also has a motor efficiency test mode that is a built-in function of the speed controller.

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 approximately 4 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. This motor is far less common.

If your existing motor is a textured graycolor and the nameplate mfg is Groschopp:
Middleby motor 66186
Image of Groschopp  brand motor

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:
  • Sensor for Conveyor Motor • Hall Speed Sensor: CTI-M-H1
  • Sprocket for Gear motor • Motor Sprocket: CTI-M-SP15
  •  Conveyor drive sprocket • 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.
