the one and only the main difference b/n them is a dc motor takes the electrical energy as its input and gives mechanical energy as its output where as in the dc generator takes the mechanical energy as input and gives electrical energy as its out put
In both the case we can't get 100% efficiency because total input can't be converted into output.
Starting of the synchronous motor using the DC generator creates a magnetic field.
The theory of converting AC to DC using a 3-phase induction motor and a DC shunt generator involves utilizing the induction motor to mechanically drive the shunt generator. When the induction motor is powered by a three-phase AC supply, it operates and drives the rotor of the connected DC shunt generator. This generator then converts the mechanical energy into electrical energy, producing a DC output. The process allows for efficient conversion of AC to DC, leveraging the motor's mechanical properties and the generator's electrical characteristics.
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.
During the operation of a DC motor, EMF is created across its terminals using an external source. Whereas, in a DC generator EMF is created across its terminal based on principle of dynamically induced EMF. So talking in terms of EMF, in DC motor EMF is consumed by the motor coil and utilized to rotate the axle. On the other hand, in DC generator EMF developed across coil is transfered to a load or a battery and consumed by them.
rectifierac motor - dc generator set
a motor Will do work by consuming power a generator is just the opposite
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.
Type your answer here... how can you change an ac motor to a dc generator
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
In principle a generator is the same as a motor. In a dc motor the voltage generated by the rotating armature is slightly less than the supply voltage which causes power to flow in from the supply. If an engine is then coupled to the shaft causing it to rotate faster, then it generates more voltage and power flows back into the supply. That is how a motor becomes a generator.
A DC generator is a DC machine that is driven by an external rotating force. It is constructed the same as a DC motor.
by a hand driven motor or always it is connected with dc motor.
since the physical construction of a DC motor and DC generator is the same,it can work either way.in other words,yes a DC motor can work as a DC generator(if you drive it by a primemover it will produce electricity).however its not possible with all AC motors.
Starting of the synchronous motor using the DC generator creates a magnetic field.
A brush-less DC motor (BLDC)
Technically nothing. They are both internal combustion engines. One is driving a transmission and a vehicle and the other is driving a generator. A generator is used to to produce DC current, that is driven by an electrical AC motor, Hench the term Motor-Generator applies. An engine uses it's own source of fuel, Gasoline, for it's power source. Never call a ENGINE a MOTOR..........
