Hi,
The mounting of an F&P. This is a smaller 90x90mm (3 5/8") square tube but am building a larger 100x100 mm (4") mount as the smaller one flexed.
A flange bearing is shown loose. In previous pictures the flange bearing is on the inside of the tube. Once again, flexing will mean I mount it closer to prop on the outside of the tube.
The turned-back F&P plastic/alu bearing holder is shown in white. A base plate is welded to the tube.
The 25.0mm shaft of the F&P meant cheaper metric ball bearings and flange bearings could be purchased, at least here in Oz. This flange bearing is allowing misalignment of the shaft as the bearing itself can move more than 30 (?) degrees. They are used in go-cart axles.
No performance figure is available yet re RPM, V and Amps. Made the mistake of measuring two phases at once, which the meter surely cannot read as the two phases are out of phase! Read 120V when the whooshing stall was heard.
The test pole is not high enough, two props gives problems during yawing and the closeness of the house and trees causes turbulence but it is a start. At least the cogging F&P is starting and turning like mad in the strong catabatic (hill) winds.
