The rotor circuit frequency is ___________ to the AC supply frequency in the stator circuit.
The __________________ of the primary and secondary electromagnetic fields is at its maximum, which causes the induced secondary voltage to be at its _______________ .
_______________ voltage equates to maximum current in the shorted secondary rotor circuit.
The impedance reflected into the primary is _______________ , which causes maximum current flow in the primary or stator circuit.
The stator and rotor circuits are generating large amounts of ___________ within the electric motor.
A) equal; interaction; maximum; Maximum; minimal; heat
