alternator does not rotate
A "prime mover" is part of a generator - specificially the thing that's causing the generator to spin (such as a turbine). It is called the prime mover because it is what is causing the generator's rotation.
Your question is unclear. Do you mean how the rotor of a d.c. generator is driven? If so, then its shaft is connected to a 'prime mover' which can be an internal combustion engine (petrol or diesel engine) or a turbine (steam, water, gas). The type of prime mover usually depends on the source of fuel available to operate that prime mover and whether it is fixed or portable.
The prime mover in a DC generator is the mechanical device or system that provides the initial energy required to rotate the generator's armature. It could be an engine, turbine, or any other source that converts mechanical energy into rotational motion. The prime mover rotates the generator's rotor, inducing a magnetic field and generating electrical power.
As we are very clear about the Power generation, that is there must be a prime mover which can develop a mechanical energy from the natural sources of energy. As in the case of steam power plant the water is headed and converted in to steam (super headed) then it is allowed to expand in to a turbine. The turbine causes to rotate (turbo machine) at about 3600rpm. Hence the Turbine becomes a prime mover here, then the rotational movement (shaft) is connected with the generator/alternator in order to produce electricity according to Faraday's law.
the excitation voltage applied the power input to the prime mover
It acts as synchronous motor by consuming power from the other generator....
Alternators are not only driven by turbines, they can be alternator can be driven by any prime mover -including 'motors' if necessary.
It was not limited to Paris, but Paris was certainly the prime mover.
The Prime Mover was created on 1961-03-24.
The prime mover is the Latissimus Dorsi.
A prime mover is a machine which transforms energy to/from thermal or electrical, or pressure from/to mechanical form. Examples of a prime mover are engines or turbines.
The masseter is the prime mover of the jaw closure.
Pronator quadratus is the prime mover in pronation of the hand.
A prime mover is the muscle that has the most influence in one direction on the joint it acts on. For example the prime mover in extension of the forearm is the triceps.
Prime Mover - 2009 is rated/received certificates of: Australia:M
a prime mover is the main muscle that causes movement. In the case of the hip flexion, the prime mover would be the rectus femoris or the ilopsoas
A prime mover (engine, produces power), an alternator (converts rotational movement to electrical energy), and traction motors (converts electrical energy to move the locomotive).
