Utterpower's 186PMG prototype Generator

120/240 60HZ AC PMG can carry loads at 4225 watts, with excellent starting of induction motors. but we rate it at 3KW Continuous and this includes high ambient temperatures.

As you can see, this is a fairly compact design, under the belt cover are two trouble free and efficient Allmand Serpentine  Drive Pulleys, in this case, the engine is fitted with a 5.0 inch pulley, and the PMG fitted with the 4.2, this allows the engine to run at lower RPM which greatly extends it's life over a 1:1 drive ratio. I think this engine is quite happy at 3000RPM, but 3600 is pushing the engine too hard to get the longevity out of it. Backing off even 300 RPMs in some of these higher speed designs can more than double the life of the engine.

This is only one example of a PMG gen set, but I'm sure you can see just how easy it is to build your own generator with the PMG and Allmand drive pulleys.

If Mad Max was designing one, he's be using the PMG and the Allmand drive pulleys, you can change the drive ratio in two minutes, and replace an engine in a few more minutes, the PMG has one moving part, if it isn't part of the design, it can't break!

This Engine has electric start, and it is not necessary to use the decompressor with the electric start. Cogging is not a big problem, and manual starting was easy for me..
