KD 341 reviewed
A new chapter 10 has been added to report KD 341 about the develoment of the VIRYA generators. The title of this chapter is: “Back to the modified 4-pole asynchronous motor with a standard 230/400 V winding”.
KD 732 reviewed
Report KD 732 about the VIRYA-14 has been reviewed. Chapter 7 has been changed completely. The title of this chapter is now: “Use of the VIRYA-14 in combinatioin with twelve detached houses”. So the twenty semi-detached houses are replaced by twelve detached houses. The reason is that the note about the semi-detached houses is no longer public. The (Dutch) note about the detached houses can be copied from my website at the menu “No wind energy”.
KD 718 reviewed
A new chapter 7 has been added to report KD 718. The title of this chapter is: “Use of a 4-pole motor frame size 100L and a 32-pole armature”. The armature has 32 mechanical poles but 4 magnetic poles and can thereforte be used in combination with the original 4-pole, 3-phase winding of a 3 kW motor. This armature has 288 preference positions per revolution and the peak on the cogging torque will therefore be very low. I think that this is the simplest and cheapest way to modify an asynchronous motor into a PM-generator.
A new chapter 8 has been added at 14-5-2023. The title of this chapter is: “Use of a 4-pole motor frame size 80 and a 28-pole armature”.
KD 580 reviewed
A new chapter 7.6 has been added to report KD 580. The title of this chapter is: Using a 30-pole armature and a different winding”.
