Where:
VM= E+(R x Im)............ motor voltage
E = Ke *n°/1000............ FCEM motor (Vdc)
Im = I motor (A)
Ri = Winding resistance (Ohm)
Ke =Voltage constant (V/kRPM)
n° = MAX speed (RPM)
V1(Dc) = VMotor
0,9x1.36
Voltage:
The primary voltage depends on what is available
locally for a single phase. The secondary voltage is
calculated from the motors voltage at the required operating
speed.
The secondary voltage V1 is:
