OUTPUT ADJUSTMENT

For the machine to produce the highest output, the rotor height should be adjusted. This involves is raising and lowering the rotor to increase the magnetic flux level.  This is necessary to match the r output of the turbine with that of the generator.

After the machine is installed, perform an initial run to establish a power output level. This can be determined using an ammeter to measure current or a digital meter to measure voltage. A good idea is to keep a logbook to note any output changes in relation to settings. After everything is hooked up, start the machine by opening the stop valve. Run it long enough for the output level to stabilize and note the current (or voltage). Then shut the stop valve.

The machine comes with the rotor set very close to the stator (the stationary part of the machine). To increase this distance and reduce the magnetic flux level, you must turn the larger bolt (3/4" head) on the top of the rotor while holding it stationary. This is done by inserting the 1/4" pin supplied in one of the holes in the edge of the rotor. Then the smaller (7/16" head) bolt is loosened. Now you can turn the larger bolt, which will force the rotor up. Each full turn of the bolt will move the rotor vertically 0.050" or 1.25 mm. If raising the rotor causes the current (or the voltage) to increase, then continue to do so until there is no longer an increase. If a point is reached where a decrease occurs, then the rotor should be lowered. This is done by loosening the larger bolt and then tightening the smaller one. Turning the smaller bolt causes the rotor to move vertically the same distance per turn as the larger bolt does. When you have found the best position (no increase in current or voltage), make sure the larger bolt is turned until it is tight. Now the smaller bolt should be tightened securely to lock everything in place. No further adjustments should be required unless nozzle sizes are changed.

When adjusting the rotor downward, it may reach the point where it will contact the stator. If this occurs, always adjust it upwards by at least a 1/4 turn of the larger bolt. Operating the machine with the rotor any closer than this will not result in any power increase but may damage the machine.

** Always turn the rotor by hand before starting the machine to check for rubbing**. Remove the pin in the rotor edge before starting the machine.

Optimum nozzle size can be found using a similar technique. First, install the nozzle insert that approximates a match to your conditions. Then try both a smaller and a larger one and pursue the direction of maximum power. Note that if you use a nozzle larger than your flow can support, air will be sucked into your pipeline.
