KD 747 reviewed

A new chapter 8 has been added to report KD 747. The title of this chapter is: “Ideas about a 30-pole generator made from a 0.55 kW, 6-pole motor frame size 80”. The magnet costs of this generator are only € 17.

KD 712 reviewed

A new chapter 8 has been added to report KD 712. The title of this new chapter is: “Ideas about a 40-pole generator with a 9-phase winding”. This generator make use of the housing of a 6-pole asynchronous motor frame size 132M.

KD 769 added

The new report KD 769 has been added at the menu KD-reports. The title of this report is: “Calculations executed for the 3-bladed rotor of the VIRYA-4.2B3 windmill (lambda design = 6.5, wooden constant chord blades) driving the PM-generator of Hefei Top Grand type TGET380-10KW-1200R for 24 V battery charging”. The rotor with wooden blades is an alternative for the rotor with stainless steel blades as described in report KD 733.

KD 733 reviewed

Two new chapters have been added to report KD 733 about the VIRYA-3.9 with tapered stainless steel blades. The title of chapter 9 is: “Use of a PM-generator of Hefei Top Grand type TGET380-10KW-1200R”. The title of chapter 10 is: “Determination of the Pmech-n and Pel-n curves for 26 V star”.

KD 710 reviewed

A new chapter 9 has been added to report KD 710 about the VIRYA-5B3. The title of this chapter is: “Ideas about a rotor with stainless steel blades”.

KD 377 reviewed

A new chapter 6.2 has been added to report KD 377 about the pendulum safety system. The title of this chapter is: “Alternative with the hinge axis below the rotor axis and the rotor before the tower”.

28 bouwpercelen in Boskant

De notitie: “Ideeën over realisatie van 22 bouwpercelen in Boskant” werd vervangen door de notitie: “Ideeën over realisatie van 28 bouwpercelen in Boskant”. De toegepaste huizen in de blokken van zes worden beschreven in de aparte notitie: “Ideeën over een blok van zes huizen met zes lofts”. De lofts die nu gerealiseerd worden zijn aanmerkelijk ruimer dan de studio’s in het eerdere plan.

Op 27-5-2024 werd de notitie gewijzigd. De parkeerplaats op gemeentegrond voor elk huis uit het blok van zes werd vervangen door twee parkeerplaatsen op eigen grond. De diepte van de percelen is nu 30 m.

Report KD 710 reviewed

Report KD 710 about the VIRYA-5B3 has been reviewed. There was a mistake in column 4 and 5 of table 5.

KD 758 added

Report KD 758 has been added at the menu KD-reports. The title of this report is: “Calculations executed for the 2-bladed rotor of the VIRYA-5T windmill (lamda design = 6.5, galvanised steel tapered blades) meant for connection to the axial flux generator of Hefei Top Grand type TGET450-5KW-300R for grid connection or water pumping”. Chapter 7 of this report gives an explanation for low head water pumping using a standard 1-step centrifugal pump with a 5.5 kW, 3-phase asynchronous motor. A new chapter 8 has been added on 27-4-2024. The title of this chapter is: “Checking of the head geometry”.

22 bouwpercelen in Boskant

De notitie: “Ideeën over realisatie van 14 bouwpercelen en één VIRYA-14 windmolen” die op mijn website stond onder het menu: “KD-reports”, is komen te vervallen en vervangen door de nieuwe notitie: “Ideeën over realisatie van 22 bouwpercelen in Boskant”. Deze nieuwe notitie is nu te vinden op mijn website onder het menu: “No wind energy”. In de nieuwe notitie wordt geen windturbine toegepast omdat die toch een behoorlijk stuk grond in beslag zou nemen en omdat hij waarschijnlijk toch niet door de bewoners geaccepteerd zou worden.
