In
case of dynamo breaking, when power is off and motor acts as a generator that
it is connected across generator if consumes mechanical energy and converts
into electrical energy. This electrical energy is supplied to load and
dissipated as heat.
On the other hand in regenerative
breaking, the electrical energy instead
of being dissipated by a load in form of heat, it is fed back to the supply line
to be used by other devices.
List
the different types of losses that occur in dynamo.
There
are different losses in a dynamo. The list of different losses which occur in
dynamo is given below-
Dynamo
