wind turbine motor test

volt test is 60v at 1000rpm
500 rpm is 34v
200 rpm 24v
100rpm 12/17v
going to use thei motor on my new tesco design vawt

the motor is a perminent magnet motor 180v 15amp......weighs about 70kg very heavy and its about 2ft long by 10inch heigh

Very informative video excellent, thanks madhelinelly

Depending on your rotor design slowing it nearly to a stop is a strong wind greatly reduces the forces on it because the blades stall (Like an airplane wing) when the rotor is not allowed to turn.

I allowed it to turn just enough to make the power to run the circuit that held it nearly stopped.

When charging a battery, the battery will limit the speed and keep the forces within reason.

Unfortunately the power of wind goes as the cube of speed so you have to design for a wide range.

In theory, the voltage should be proportional to the RPMs. It may be a little lower at the high speed end due to various losses.

At the low end, the ripple may make your meter inaccurate I have one like the you you showed. They are low cost but also cheap.

I have designed the charging controller for a home made system. A trick I came up with (you are free to use it) is to place a really heavy electrical load on the generator when no charging is needed
