KD 437 reviewed

A new chapter 14 has been added to report KD 437. The title of this chapter is: “Adding of a centrifugal weight to a blade”. As the aerodynamic moment is rather small, a larger pitch moment can be obtained by adding a centrifugal weight. This chapter describes the influence of the weight on the pitch moment depending on the position of the weight.

KD 723 added

Report KD 723 is added to the menu KD-reports. The title of this report is: “Ideas about an 18-pole, 2-phase permanent magnet generator using the housing of a 6-pole asynchronous motor frame size 100 for driving a 0.55 kW motor of a centrifugal pump”. Chapter 6 describes an alternative 6-pole armature for which the standard 6-pole winding can be used.
