Default Re: EZ-GO L6 72v Beast!

The dealers can only see the values at or below their access level. Everything higher than that is invisible to them. Even the factory where they are made cannot access the higher levels that I have access to. The large AC motor in the L6 is rated for 12,000 RPM. I only need to turn it up to 8,000 RPM. With the factory sized tires on the L6 72V, that means top speeds in excess of 50 MPH. So 25 or 35 MPH are relatively minor speed increases compared to the capabilities of the design.

AC motor speed is driven by the AC drive frequency. DC carts must increase voltage and current to run faster. So the controller is not being overdriven. These 72V carts are barely using their capabilities.

So while the dealers can see that a L6 is running faster, they cannot view or document how it was done. Even if they plug into the controller and try logging the speed increase for proof, it will fail to show any changes. They are totally invisible to a lower level programmer. The VCL is being told that it is still operating at stock RPM and speed. So nothing to report out of the ordinary.
