reports KD 648 and KD 484 available
« on: December 08, 2017, 05:33:42 AM »
The title of KD 648 is: "Ideas about a 38-pole permanent magnet generator for the VIRYA-3B3 windmill using the housing of a 6-pole, 3-phase, 1.5 kW asynchronous motor frame size 100 and 57 neodymium magnets size 40 * 7 * 3 mm". The 38-pole generator is an alternative for the original 4-pole generator of the VIRYA-3B3. The magnets costs of the 38-pole generator are relatively low.

To give an impression of the rotor of the VIRYA-3B3, the design report of the rotor, KD 484, which was already made in 2012, is also made public. The title of KD 484 is: "Calculations executed for the 3-bladed rotor of the VIRYA-3B3 (lambda design = 6.5, wooden blades)". The blades of the VIRYA-3B3 have a constant chord and a constant blade angle and can therefore be manufactured rather easily from a wooden plank.

A picture says more than thousands words, so I have added a picture of the VIRYA-3B3 rotor as attachment.
