Friction[Nm/Rad/s] 1m Friction of the bearing in Nm per Rad/s
JR[Kgm2]] 100m Rotor inertia
LS[H] 15m Winding inductance per phase
RS[ohm] 10m Winding resistance per phase
Ke[Vpeak/(Rad/s)]]=[Nm/A] 1 Torque / back emf constant in [Vpeak/Rad/s] or [Nm/A]
polepair[.] 1 Number of pole pairs

Function The input RST is transformed from three phase into the two phase d-q system.
Vr= Vd*sin(theta) + Vq*cos(theta) + V0
Vs=Vd*sin(theta-2pi/3) + Vq*cos(theta-2pi/3)
Vt= Vd*sin(theta+2pi/3) + Vq*cos(theta+2pi/3) + V0

Status Standard
