Hola, , a mi pregunta si es corriente continua pulsatoria, o alterna , variador-motor brushless, respuesta:


***************
Hello,

current from 3phase controller to motor is specially modified DC current to AC values. So it is like AC.
Best regards

Drawing of a very simple manual three phase-system. Controllers do the same only a little bit faster. Transistors/FETs do the switching, microprocessor does the thinking. This will give you some idea.

'Our' model motors don't use a sinusoidal signal but an approximation of a sinus, a trapezoid signal. At partial load, the trapezoid shaped voltage is PWM modulated ("one of these days I'm going to cut you into little pieces"). Voltage is chopped/spikey but current is not, motor induction smoothes the motorcurrent spikes.
