WebMar 26, 2024 · First, harmonics reduce the motor’s efficiency. Harmonic content makes it harder to magnetize the copper and iron in the motor’s stator and rotor, causing higher eddy current and hysteresis losses. If harmonic frequencies exceed 300 Hertz, the skin effect compounds these losses. Second, all these extra losses manifest as additional heat.

WebSo, this is a really simple demonstration of a way to generate sines and cosines with this rotating vector idea. We're gonna be able to generate this rotating vector using some ideas from complex arithmetic and Euler's formula. I find these to be a really beautiful pattern and it emerges from such a simple idea as a rotating vector. http://www.qs-motor.com/product-catagory/yuanqu/
