It is fed from a single phase source with two connections (L1,L2) via a frequency converter (34) with three output connections (35,36,37). The supply circuit has a switch (42) which in a first position, respectively connects the three output connections to the three connections of the ...
we need to find the relationship between the motor slip (s) and the firing angle (α) so that the motor torque remains constant. The load-phase angle of the rotor circuit can be determined as follows: ϕ r = tan -1 (X r ⋅S)/R r (1) Where X r and R r –the ...
