What happens when ac supply is given as excitation voltage instead of dc
supply

Answer Posted / Mandira Budiyal

If AC supply is used as excitation voltage for a DC motor, the motor will not run efficiently. The motor may overheat and suffer mechanical damage due to the conversion of AC to DC through internal commutation, which can lead to reduced efficiency and increased power loss.
