The field winding should be designed for a voltageThe field winding should be designed for a voltage from 15-20% less than the exciter voltage.

The field winding in electrical machines, such as generators or motors, should be designed to operate effectively with a voltage from 15-20% less than the exciter voltage. This guideline helps ensure optimal performance and longevity of the machine by preventing over-excitation of the field winding, which can lead to overheating and potential damage. By designing the field winding to accommodate a lower voltage, it allows for better control and stability of the machine’s operation, contributing to efficient energy conversion and minimizing the risk of electrical faults.
