Final answer:
The question is about a 208-v four-pole 60-hz y-connected-wound rotor induction motor, rated at 30 hp. The terms describe the characteristics of the motor, including its power output, number of magnetic poles, supply frequency, voltage, coil configuration, and rotor type.
Step-by-step explanation:
The complex nature of the 208-v four-pole 60-hz y-connected wound-rotor induction motor can be broken down in parts for better understanding. Firstly, the rated power is 30 hp, which suggests that its optimal operating power is around 30 hp.
The fact that it's four-pole indicates that it has four magnetic poles formed by the windings of the stator. A 60 Hz frequency reflects that it has a stator magnetic field that rotates 60 times every second.
As for the phrases '208-v' and 'y-connected', these are referring to the stator's electric supply. It's a three-phase 208 volts system, and the stator coils are connected in a 'Y' or 'star' configuration. Concerning the 'wound rotor' term, it signifies that the rotor windings are physically connected to the external circuit, typically through slip rings and brushes.
