Hi,
I have an old Agemaspark H300 which i am trying to get up and running in my garage. Due to the control system and spark generator as well as 2 separate 3 phase motors, which are all powered from 1 rather complex (415v 3 phase, no neutral) transformer, I am looking to build a 3 phase converter to power the whole thing. The rating plate gives 220/550v and
2KVA which is believe is well within the 240v supply. I have seen loads of USA designs for phase converters BUT it seems the USA has a 2 phase 240v supply unlike our single phase 240v supply. Having scoured MANY web pages I am unable to find a UK design. Does anyone have one or know of one I can beg, steal or borrow. I have the excellent book "electric motors in the home workshop" by jim cox, which shows some methods of converting motors and building a static converter for motors, but i am unsure if the resulting variations in voltages are ok to feed the transformer. I am sure someone has built a suitable unit and can help me out here.With regard to my previous endeavors I also have 1 or 2 areas of doubt as follows.
Does a rotary converter "idle" motor need to be of the dual voltage variety? Some suggest using an older type of motor for this job, but the older type seem to be all single voltage types?????????
If i use a rotary converter will I get 415v, 440v or 480v ( i suspect this will depend on question 1?)
One of the motors (0.33hp 415v star) drives a pump for the flushing tank, it might be easier just to change this for a single phase (central heating) unit. The second (0.25hp 380/440v) is part of a hydraulic power pack.
The spark generator is rated at 10amps at i THINK 100volts.
The control system is an old analog type together with a moog hydraulic system.
Any suggestions very welcome. Regards, pete
