What will happen if twice the rated voltage is applied to a
DC motor?
Answer Posted / roysayan01
Firstly the brushes and commutator will simply burn out
because of the high current. Secondly insulation depends on
rated voltage and if double the rated voltage is applied
insulation failure will take place.
