During operational tests of a separately excited DC motor, the motor, while running at a constant velocity of 1800 revolutions per minute, produces an output voltage of 160 V on an open armature circuit with a steady field current of 1.2 A. The motor's inherent resistances are listed as: • Field Coil Resistance: 30 ohms • Armature Coil Resistance: 2.5 ohms Subsequently, this motor is reconfigured as a series motor connected to a 90 V power source. It continues to draw a current of 1.2 A. Considering these altered parameters, could you determine the magnetism of the motor, represented by the product kao?
