- Why can an induction motor never operate at synchronous speed?arrow_forwardThe reason why the starting torque of a series motor is higher than a shunt motor is because the series motor has O more current flowing through its armature O a stronger net magnetic field around both coils during the inrush of stator currentarrow_forward
