World 3 phase Conversion Standards  Are a Crock !


First:  In a so called  'Rotary Converter',   electrical power is not 'converted',  it is  'conditioned'.

It can be rectified or inverted.   But 'converting' it to 3phase is nothing more than a conditioning process.

Rotary Phase Converters are not generators.   They are made up of a set of 3 'windings' that are mechanically configured and equally spaced about a circle.   Wow, just like in a 3 phase motor. 

The single phase power is connected to two of these windings.   This in itself is enough to keep the motor spinning when supplied power, although the torque delivered from the motor will be at two points around this circle and the third area will be passed due to momentum.

However this won't allow the motor to initially start by itself when power is first applied.   The 60 cycle AC power applied to only two of the three windings will cause the motor to 'bounce' back and forth between them.   This produces the 'hum' we call 'single phasing'.   It will happen with commercial 3 phase power when one leg to the motor is disconected as with 3 seperate fuses (one being blown) and the motor re-started after being stopped or if the motor is running under enough load to prevent it from having enough momentum to continue rotating past that third leg that is no longer powered.

The power delivered to our motors (anywhere) is the result of many years of experimenting to find the easiest most efficient methods so that the power company can actually make money by doing so.

There are no secrets about it's conditioning and delivery not available to anyone who cares to study them.

The standards  (if one wants to identify it as such)  are whatever is required by the user.   Not determined by a 'converter' manufacturer who after all wants to sell a specific brand over all others.

The  'standards'  that are in place are set by the power company, not by  'converter'  companies.

It's the ignorance 'we' have of these methods that allow them (through omission of truth),
to lie to us about how technical this 'conversion' is or is not.

Most 'phase converter sellers'  will sound much like a preacher,  as if they really believe what they are saying.

They are able to sound sincere in what they are saying because they tell enough of the truth's  that are generally accepted and allow us to assume the rest.   From this kernal of truth we are expected to accept it all.   And in our ignorance of the 'complete truth' we assume wrongly in certain areas because we arn't familiar with the basics.  Tripe and dishonest to create more of a business than  is deserved.

They 'omit' the actual 'secrets' that make this conditioning possible.  These 'secrets' are not secret really.  They are taught in any basic electrical course.   It's just that for the purpose that one is taught electrical usage it is assumed that the electrician will work within the standards set by the electrical companies.   And the application of 'conversion' is simply one that is not addressed in an average electrical course 'as it relates to powering 3phase motors.   For this standard delivery of power to the consumer conditioning or 'conversion' is normally not required.   After all, they deliver power in several usable voltages, and motors are made to suit these.  

The user can transform, rectify, or condition this power as needed.   This power has been 'generated' and delivered to us.  It doesn't  need to be  'generated'  by us.  We just need to 'condition' (adapt) it to meet our needs.


The key to decide whether they are being truthful is simply to  'read'  their stuff comprehensively and decide if they are really answering your questions or whether they sound like a politician speaking in general terms leaving 'plausible deniability'.

They want you to believe that it takes many years of 'engineering' know how and experimentation to produce a 'rotary phase converter'.   And that we, the user cannot possibly expect to have the knowledge to accomplish this 'conversion'.

This is the lie.  I've been using 'phase converters' for 50 years.  I've built literally hundreds.  I've distributed the infomation to many thousands of people with instructions as to how to build them and apply them to many different applications.   In those 50+ years I've yet to burn up a motor used as a 'converter' or damage any of the many devices, machinery, power supplies, welders, etc, that I've powered with them.

So if one would simply rather pay hundreds of dollars instead of ten's of dollars for what should be a routine application then buy from a so called 'rotary converter' manufacturer.    No doubt you'll be satisfied with it's performance.  I've never been able to recommend this partly because I've shown so many industrial electricians and maintenance men how to simply 'condition' their power as needed and 'none' have ever been forced to revert to buying a comercially manufactured one in these 50+ years.  

A rotary phase converter manufacturer is doing nothing more than assembling a converter exactly the same way I would need to  for my own use.

The important thing for one to know is that the methods are not magic or unknowable.  They are actually easy enough to do that the average person can follow the steps to accomplish it without even understanding why or how it actually works.   Those who want to sell completed converters will allow us to assume it's more difficult due to it's technical nature.    That would be fine if they did not deliberately tell us that we 'best not try' because it's just too tough or technical for us.  Thats a lie.
