I had a salesman in yesterday pushing Miraculous motors Corporation, Ample Amp motors. I have been around the track but this is the first time I have seen this one.
I have found a few references here but they don't address the secondary winding scheme. Any information would be appreciated. And No I do not still believe in the Easter Bunny. Woody |

woody,
I remember that marke discussed about this motor some times ago. Please check using the search function in this forum If you have some useful news about this motor, please write it. Otherwise it is better to forget this question. Regards Mario -------------------- |

As with all these schemes, you need to do your own testing to prove the theory, don't rely on the salesman!!

This suppossed new technology looks to be remarkably similar to the Wanlass and Unity Power Factor motors of the 1970's. The patent implies that winding coil insertion is different from the Unity and Wanlass design.but the basic theory seems the same.
the company claims to have a proven technology that has been tested and studied extensively at Oregon State University's motor research facility. I have made many attemps and have called Oregon states motor research facility several times but have not been able to retrive any information on this technology. ( If there is an independant study on the ample amps motor) you would think it would be included with the company sales fliers and on their web site. Without an independant study the facts are heresay. Now lets get down to theory. The company claims to lower the amp draw of the motor to save energy, The company also claims to raise the power factor of the motor to 98 to 99% once again to save energy. This sounds like a win win situation but we have to look at the corrolation between these two values to understand how power factor and amp draw effect billable power. Formula for billable wattage for 3 phase power. Watts= 1.732 X volts X amps X power factor. Lets use the above formula to calculate the wattage rating of a standard 50hp 460v 3ph motor running fully loaded. 1.732 X 460 X 60.4 X .83 = 39,941 watts of billable power Now lets use the formula for a converted motor with a power factor of .99 drawing 52.5 amps. That would be a 15% reduction in amp draw. 1.732 X 460 X 52.5 X .99 = 41.409 watts of billable power. As you can see even with the reduction in amp draw the high power factor ( converted ) motor will actually use almost 1.5KW more power than a standard efficiency off the shelf motor. If you are going to try this technology my best advice is to check all applicable parameters of the old motor prior to removal and conversion. Line voltage, Amp draw, power factor and rpm with your own equipment. Also you may want to speak with your representative from your local utility and they can probably help with testing. Upon installation of converted motor, test all parameters again and compile your own information on if this technology will actually lower your power bill. Don't believe the people selling the technology. Also don't get drug into conversations about KVAR, Apparent power or any other electrical values that are not included in the fornula above. You only pay for what is included in the formula ( True Power ). QUOTE (woody @ Dec 3 2008, 02:58 PM) I had a salesman in yesterday pushing Miraculous motors Corporation, Ample Amp motors.
