Hello,
today i messured 3 standard alternators and my DIY alternator.
Driven by my small lathe, i could test as far as 700W Input.
Im happy with my work and suprised that 20 years of technical development nothing change in effictiviness... ALternator 1: BJ:1991, Alternator 2: BJ: 1996, ALternator 3: BJ 2014
Here my results
