simulate

I simulated ( Multisim ) circuit and checked transistor model I found that in transistors model's description. I noticed BF in description what is it? Is it beta ? If it's same with beta why in model BF is constant when beta not constant? For example : .MODEL 2N2222_Multisim npn +IS=1.87573e-15...

Good afternoon, I have developed a Vector Control for a PMSM motor in Simulink using Simscape Electrical but my motor is not spinning. I have tried applying various speed values but nothing happens. I am applying a step signal from 0 to 300 but the motor speed still doesn't move. My error...

Hi everyone, I am using the Surface Mount PMSM block from the Motor Control Blockset in Simulink to develop an FOC algorithm. The output of the block (PhaseCurr) is a 1-by-3 array containing my 3 phase currents a, b and c. How can I extract the 2 currents (phase a and b) from my array in...

Hi everyone! So at work we have several engine simulators and for the ones we currently have engine speed sensors connected to we went about it by using a DC motor spinning a magnetic pulser disc (found here) with the sensor mounted directly in front. Though this works fine, I'd like to start...
