Electrical principles for wind turbines
Most domestic turbines use permanent magnet generators. Provided they are well made, these are simple and reliable, but when you spin the shaft, there is a cogging resistance to movement which prevents them from starting up in low wind conditions.
On top of this, most generating systems don’t start putting electricity into the grid (or batteries) until they get over a certain speed. Your turbine might be spinning, but producing nothing.
We are working with a generator which has no cogging. The start-up is smooth and enables the blades to spin even in very light winds. We are matching this with an inverter which cuts in when the turbine is at very low revs. This cobination means that your generator will be working in a wide range of conditions when most generators are effectively redundant.
