Commercial coffee machine motors – Images and information.

Measuring commercial coffee machine motors.

Commercial coffee machine motors shown here are available in the online shop. First of all the purpose of this post is to provide information and images relating to those products.

Motors vary in size, power rating, volts, revolutions per minute and more. Most noteworthy is the difference in base plate design. While a replacement motor of similar specification will often work, the fixing holes or slots may be different.

Manufacturers design base plates on commercial coffee machine motors to different standards. Fitting a replacement spare part motor therefore often requires further fabrication.

Distances between slots and holes are shown in the first table below. All dimensions are approximate, supplied for comparison purposes. Dimensions should be compared to existing parts in order to confirm compatibility.

Commercial coffee machine fixing hole and slot dimensions.

Motor typeDistance between hole or slot centre (length ways).Distance between hole or slot centre (width ways).Diameter or dimensions of hole or slot.
RPM external motor.95mm86mm7mm
RPM standard motor.105mm43mm7mm width, 23mm length
RPM slimline motor102mm90mm10mm

Focusing on the three main types of RPM pumps most noteworthy is one of the three being external. External pump motors being used most commonly with CMA, Astoria and Costa espresso machines.

The external motor requires a wiring loom for connection, If the loom is absent a new one needs to be fitted or made. Check the internals of the machine to see if there is a pump motor present there.

Choosing a motor

Especially relevant when choosing a replacement motor is the specification in terms of wattage and RPM if known. The closer the variables, the nearer the compatibility. A significant difference will be noted when using less or more power.

The temptation to fit a slim line motor as a replacement for s standard motor should be avoided for instance. This is because the wattage differs significantly. Performance will be incompatible or indifferent at best.

The next table illustrates variables of the models:

 

MotorTypeVoltsHZWattsRPMMFAMPVL
Standard RPM11002703230501651370101.6450

In addition to the information shown above the table below list common manufacturers utilising motor types. Most of all note well some manufacturers use more than one type. Often dependant on the model for the coffee machine. Furthemore where available are manufacturers relevant part numbers.

Faulty motors are not worth repairing, rather it is not economically viable to do so. A very noisy motor is most often on the way out. The job of the motor is simple it spins the pump and nothing else.

All three motors use a standard Fluidotech PA1504 pump head, the head bolts on to the motor with the supplied clamp, which is bolted on. The shaft is flat and oblong shaped.

Fluidotech PA1504 pump head.

The Fluidotech PA1504 is the most used pump head on commercial coffee machines. Utilising 3/8 inch connectors for the hoses. Most of all the flow rate is measured at 200 Litres per hour.

Pump heads are water lubricated. A pump head left unused for prolonged periods is therefore subject to fail.  Pumps stored in minus temperatures will freeze, expand and consequently fail also.

Finally pump heads fail more often than motors, it is not uncommon to replace a head every 12 months on a well used machine. In addition need to adjust the pressure of an existing pump is merely an alarm signalling the imminent demise of the pump.

      whoops sorry for the late reply, I think you bought from the site last week anyway ! The slimline pump still uses the standard rpm pump head, correct, thank you for the question, Scott

    My brother recommended this website. He was totally right. This post truly made my day. You can not imagine simply how much time I had put in for this info! Thanks a lot!
