Basic operational voltage equation of a DC motor is given as E = E b + I a R a    and hence,     I a = (E - E b ) / R a Now, when the m...

A running motor may be brought to rest quickly by either mechanical braking or electrical braking . The mechanical braking is applied by me...

Speed of a DC motor Back emf E b of a DC motor is nothing but the induced emf in armature conductors due to rotation of the armature in ...

Theoretically, the same DC machine can be used as a motor or generator. Therefore, construction of a DC motor is same as that of a DC gener...

A dc generator converts mechanical power into electrical power and a dc motor converts electrical power into mechanical power. Thus, for a...
