not run in either direction
dc series motor
leave the brushes of the motor at the position where the induced voltage is zero
Both dc generator & dc motor are the same and known dc machine.when we give an electrical supply to the dc machine a torque developed due to flux intraction & works as motor.but we used dc machine as a generator we rotate the rotor or prime mover by using external sourse.due to this the rotor conductors cut by the stationary magnetic field and electrical power is generated as per faradays law.Here the main difference is when we giving electrical energy to the rotor of dc machine produce torque(motor)but when we give the mechanical energy to rotor it produce electrical energy(generator)
rectifierac motor - dc generator set
A DC generator, or "dynamo", is very similar to a DC electric motor but cannot be described as "exactly the same as a motor" because a DC generator's designed purpose is not to "use" electricity (which a DC motor does) but to "make", or "produce", electricity.
A DC motor converts electrical energy to mechanical energy. The converted energy is provided to a mechanical load.A DC generator converts mechanical energy to electrical energy. The converted energy is provided to the electrical load (voltage, current referring load).A DC motor can be used as a DC generator and vice-versa.
dc series motor
a motor Will do work by consuming power a generator is just the opposite
leave the brushes of the motor at the position where the induced voltage is zero
all the electrical machines can be run either as a motor or as a generator. but dc machines, A motor can be run as generator and vice versa with little modification
AC stands for alternating current, and DC is direct current. A motor is a device that uses electrical energy to spin. An AC motor uses AC voltage, and a DC motor uses DC voltage. http://ezinearticles.com/?The-Difference-Between-AC-and-DC-Electric-Motors&id=193767

Conversion of electrical energy into mechanical energy
A DC generator, or "dynamo", is very similar to a DC electric motor but cannot be described as "exactly the same as a motor" because a DC generator's designed purpose is not to "use" electricity (which a DC motor does) but to "make", or "produce", electricity.
It can be found on an electrical generator set. It is used to supply the DC voltage for the field coils.
