For what purpose are synchronous motors used? Explain the V curves of the synchronous motor.
A motor works when it is connected to AC. By mistake you connect it to
DC, but you see it also works with DC. What kind of motor is it?
The 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 current
