Notice! Unique3phase has materials that teach how to build two types of three phase converters.
The transformer converter and the rotary converter.
If you look at my materials and study what I do, you will come to the conclusion that those are two types of converters that can be made cheaply at home. They will work great and run most of your equipment.
However, in the interest of full disclosure, if you have a machine shop and need to run machine tools, such as a lathes, milling machines, CNC machines, and other multimotor, variable speed, instant reversing tools, you are probably better off with either a VFD or the PhasePerfect© unit. The VFD’s can be purchase used, and they work for small motors. The PhasePerfect© unit is more expensive but gives you three phase power with a form of regenerative breaking for reversing applications.
With that said, what good is the rotary or the transformer method converters? These two types of converters are simple and cheap. Between the two of them you can run just about anything. Welders, resistance heaters, drill presses, pumps, ventilation fans, dust collectors, etc. You can use either method to run multiple motors.
What are the differences between the rotary and the transformer method?
The problems with the rotary converter, that I find annoying, is first it doesn’t offer much in the way of starting torque. It is a known fact that the rotary converter cannot supply full starting and running power to the motor. The rotary converter manufactures get around this by telling you to change pulley sizes or turn down the pressures, etc. This is their way of dealing with the problem. Second the rotary makes a lot of noise and vibration. This means for a quiet shop you need to mount it in a sound proof box outside with plenty of ventilation. Third it needs to be running, and up to speed before you can connect up your load. With an air compressor, how do you make sure the rotary is on when the air compressor kicks in? You leave the rotary running all day. This brings us to number 4, the rotary is not efficient and wastes electricity.
The above drawbacks lead to what I call the sizing problem of the rotary. To get your largest motor to run you have to size the thing 3 times larger then your biggest motor. So to run a 10 hp motor, you need a 30 hp rotary. That is a fairly large motor to start from your single phase supply. It is going to dim the lights. Once it is running you are okay. But wait, you wanted 3 phase power. Now you have it. You can run that 1 hp drill press, and the 3 hp saw, and the ¼ hp pump motor, all from the 30 hp rotary. See the problem! You will be running a 30 hp motor all day, just to have the power to run a 3 hp saw, when you want to make a cut. If you think you are going to turn the rotary on an off all day, think again. Not only is it inconvenient, but it is going to dim your neighbors lights multiple times a day. Not good.
If you need to run a motor efficiently and need full starting and running torque from it then you need a transformer converter.
You can build a transformer converter.
A transformer converter does not use a motor in the converter. It runs your motor directly. If you have a ten horse machine then the converter runs your machine. No extra, oversized, motor needed. It is totally quiet. It does not need to be running first. You can start the converter and the motor starts right along with it. There is no big heavy surge current dimming your lights and your neighbors lights. The transformer method actually is a form of soft starting. If you have an air compressor to run, or air conditioning compressor, or anything for that matter, you would have to leave the rotary converter running the entire time. So when the machine is called for, it can start. This is a huge waste of energy not to mention distracting noise.
Like to have a small part time business that is fun and profitable?
If you want to get into a business that will provide for you and your family this could be it. Building converters and setting them up for others.
If the only thing my materials had to offer was how to build a rotary converter, I wouldn’t be so confident that you could have a good business with this. You would just be competing with all the other rotary converter makers. But with the flexibility that my system offers, I feel you could do this and have success. Why? Because not every situation is the same, and to just tell some one “You need a rotary” is not the answer. By being able to make a transformer converter, and also a rotary, you are in a position to offer the customer a system that will really work for him. He will be very happy and recommend you to others. Word of mouth is a powerful advertising method. As you grow you can become an expert on the use of the VFD’s and the PhasePerfect© units. This increases your profits and ability to meet customers needs.
Because I show you how to not only modify commercial transformers but also how to make your own transformers out of readily available parts that can be bought for pennies on the dollar you have a flexible business plan. You can manufacture when you don’t have a customer, and use what you made in the off time when you do.
One thing I have learned is that in countries outside of the USA there isn’t the huge availability of used parts like in America. This system of mine is ideal for those situations because you can make what you need from what you can scrounge up.
Don’t take my word for this! Look at some of the videos I have on the site and also read over my testimonials and positive feedbacks from eBay.
Where and how to buy my instructions
Visual learner? Then order the DVD set and see how we hook everything up and modify and build the transformers. There are three DVDs in the set. One is devoted exclusively to the rotary converter. The other two give complete details on the transformer converter and making the welder. The DVD set is $22 and $3 postage to the USA. $5 postage to other countries. Note: For a limited time I am now including the eBook with the DVD set. That’s right buy the DVD set and get the eBook download for free!
Note: Because I am adding the eBook at no charge, the download link will be sent to you within usually less then 30 minutes. Your Dvd’s will usually ship the same day or next day, not counting holidays or Sundays.
Want a hard bound book? Then order the hard bound book from Amazon. It is $28 and free shipping.
Note; When you go to my Amazon page you will see a statement that the DVD set is no longer available. That is correct, it is no longer available from Amazon. I could not give the dvd set the proper support through their service. It is still available through this website.
Want it fast? Then buy the eBook and have it in minutes. The eBook is hosted on eJunkie servers and you will pay them using either Pay Pal or Google checkout. It is a 14 megabyte PDF file and is about 117 pages. Cost of the eBook is $15.
Need Support? I offer free email support with the sale of all my materials. Sometimes it doesn’t matter how good the presentation is, there is always going to be some small question that I can answer in a minute or two, and have the person continuing on with success. Reflected in the price of the products is the fact that I give a person as much time as he or she needs to get their converter built.
Trouble with downloading something? Get the eBook on Cd mailed to you. Only $15 plus 3 for shipping.
