  • Mazzer Super Jolly

    A quick one...Ive read the SJs can be 3 or single phase. How can you tell a 3 phase from a single phase machine?

    Cheers

    You cant from the outside as they look the same
    The only visible difference is the power plug and the label

    This is a 3 phase plug

      From watt(lol for AM)I can see there were some 3 phase US spec 220v(110v being norm)ones floating around? Shouldnt find these in aust I wouldnt imagine......pretty sure Robur and Kony still come in 3 phase in US? Chrisll know(talk coffee)

        Never heard of a three phase Super Jolly. The only Mazzer I know that comes in three phase is the Robur.

          Nope- me neither. You have 3 phase so that you can run larger burrs in conical grinders for hyper busy operations- i.e in a continuous operation Robur doser version (83mm v 71mm burrs). No value whatsoever in 3 phase and the 64mm planar burrs of a SJ.

          You can pick a 3 phase grinder by the 3 phase plug on the end of the cord :

            Thats great information thanks. Ive been looking around and someone told me that they had one but it was 3 phase (they were relying on info someone else gave them :-? ). Im new to all of this so I wasnt sure if it was correct or not. The grinder Ive seen certainly doesnt have one of the 3 phase plugs shown, its a standard household looking plug.

            Thanks for your comments, its appreciated!

              Can someone please explain the US spec 220V 3 phase Robur to me? (am i right in saying this?) in laymans terms(remembering im not and idiot), why is it able to run as chris stated above, i know im wrong but lol, we have 240v power couldnt we run the 83mm burrs on the Robur on single phase? (ready for an AM speel)

                3 Phase is usually around CURRENT / LOAD capacity/needs etc and wiring of said device must be suitable.  

                You can have 3 phase with low current or higher currents.  You can have very high current single phase devices..


                We have tiny motors that are the size of ya finger nail that are 3 phase... Maybe not 240V but it is about loads / speeds and finer control etc.


                It is all about the effective management of Power and Losses.  Thus often in the USA 3 phase etc will be 240/230 etc..  They just need to roll out 240 across every thing else  ;D

                I will let Mal explain the maths involved in 20 words or less  


                Just remember - The masses dont need to know... Just tell them it is for heavy duty and hope they go away.

                  As Mal said in http://coffeesnobs.com.au/YaBB.pl?num=1272288185
                  "Its more a matter of throughput rate in a commercial situation. Because of the increased surface cutting area mentioned above, Conical Burrs can not be run as fast as Flat Burrs because the significantly greater cutting area requires significantly greater torque as a result."

                  3 phase motor can have greater torque than 1 phase.

                    yep, i was aware that 3 phase has more torque that single, my question was.......why.....why is 240 in the US 3 phase, and 240v here is single phase, not what are the benefits......

                    So what your saying AM, is that the wiring carries more current in order to handle the load of larger burrs in the 3 phase model, what would be a relative current draw approx under the same load for the following devices:

                    US
                    110v -- single phase Robur 71mm
                    240v -- 3 phase Robur 83mm

                    AUST
                    240v -- single phase Robur 71mm
                    415v -- 3 phase robur 83mm (God they are MASSIVE burrs!)

                    Cheers

                      Our 240V are 10A, I would presume US 110V would have to be 20A- for the standard stuff...

                      Dunno what their version of 3 phase is :

                        As I recall in the US single phase is 110 volt and three phase is 240 volt Delta.

                          Na... But ya will be after Monday  

                          It is the sort of anal info that may add to deeper understanding, but is not any where near as simple as some think or state  

                          As I said we have miniature 3 phase stuff and it is not 415V  ;D

                          The physics behind angular velocity was never my super strong point and then when you get into burrs and crushing pressures and  Newton third law to compound the issue etc etc etc   [smiley=thumbdown.gif]


                          Putting it back to just Voltage and current is the fob off I mentioned before... The masses do not need to understand... Black box theory - ya put  Y in and X comes out..  

                          Try to explain in detail how TVs work and the signal / data is transmitted / received... The masses do not care and would be beyond the majority.  


                          For that matter the 7 layers of the OSi model in basic networking principles...   Opps lost a few young IT people with that one... Trust your still with me Mr IT  Wsully  [smiley=vrolijk_26.gif]

                          One needs to be able to talk to some one like Sheldon out of the The Big Bang Theory.... BUT dont get pissed when you can not comprehend what they are saying.

                          My mate and I have been through this any number of times and my head still hurts even years later..  If ya have ever seen two grown men shouting and thumping tables and scribbling all over white boards and then storm out side and have a cig and a coffee.. That was us  8-)

                          It comes down to very in-depth vector analysis of all the factors and forces.. It is almost like a complicated matrices but adding in vectors and lots of 2nd and 2rd order stuff.. Yea... Painful.
