because the dc motor will act as dc generator as same as dc generator acts as a dc motor .so it is called as dc machines.
AnswerBecause generators and motors are machines, and operate on d.c.
'A.C. machines' are generators, Transformers, and motors which operate on a.c.

What is a generator?
A generator is an electrical machine that produces electricity. It must be turned by a prime mover that can be an internal combustion engine (driven, usually, by diesel oil or gasoline), or it can be a turbine, driven either by superheated steam or by water falling from a reservoir. (The latter is known as "hydro-electric power generation.")Before today's solid-state voltage inverters were invented, electric motors were often used to drive generators to produce a different type of electrical power (for example, to produce dc power from an ac service or to produce 3-phase ac power from a single-phase ac service).For more information, see the answers to the Related Questions shown below.In electricity generation, a generator is a device that converts mechanical energy to electrical energy for use in an external circuit. The source of mechanical energy may vary widely from a hand crank to an internal combustion engine. Generators provide nearly all of the power for electric power grids.The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities. Many motors can be mechanically driven to generate electricity and frequently make acceptable generators.

What are Hans Christian Oersted inventions?
Hans Christian Oersted is known for his discovery of electromagnetism in 1820, which laid the foundation for the development of electric motors and generators. He also contributed to the understanding of chemical bonding and the nature of diamagnetism.
How is electricity produce in a coil of wire?
Electricity is produced in a coil of wire when the wire cuts across magnetic field lines, inducing an electric current. This phenomenon is known as electromagnetic induction and is the principle behind the operation of generators and electric motors.
