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.

∙ 13y agoThe main difference is how power is put to them. A dc motor and generator are the same thing, they just feed them power at different spots. For a motor comes in the commentator through the stater back to commentator. A Generator brings power into the stater through the commentator back to the stater. Some old school small engine used one unit to do both jobs they just feed power to the correct side for the job they needed it to do.

∙ 13y agoA DC motor can be operated by just supplying a DC voltage to it.
A stepper motor needs to have an external controller to feed its coils (3,4,... coils) one at a time or using a special sequence.
Internally, the DC motor contains several coils (1) and several permanent magnets (or coils) (2).
The magnetic field of the coils (1) is switched such to interact with the magnetic field of magnets (or coils) (2) therefore creating a moment of rotation.
The switching of the currents is made internally, through brushes or electronic circuits.
The stepper motor has a similar construction, with one noticeable difference.
Internally the stepper motor has coils (1) that are fed externally with currents by the controller, creating an interaction with the magnetic field of the magnets (or coils) (2) such that a rotational moment is created.
If the controller does keep the same coils supplied with current, the stepper motor behaves like 'locked'.

A DC motor converts direct current electrical energy into mechanical energy.

∙ 13y agoOne (the motor) use electrical power and converts it to mechanical rotational power and the other (the generator) does vice versa ie converts mechanical rotational power to electrical power
Wiki User
∙ 13y agothere is absolutely no difference,since the operational functions on both are mechanically alike.the only slight difference which doesn't really matter is the functional gear.

∙ 12y agoThe basic difference between a motor and a generator is that a motor converts electrical energy into mechanical energy while a generator converts mechanical energy into electrical.

How does the starting of synchronous motor using dc generator as a load work-?
Starting of the synchronous motor using the DC generator creates a magnetic field.
What is a DC generator the same as?
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.
What is the difference between a DC motor and a generator in terms of EMF?
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.
What can change an ac current to a DC current?
rectifierac motor - dc generator set
Can you use a dc generator as a dc motor?
Yes you can turn a motor into a generator, if it is a permanent magnet motor.
What are the Difference between dc motor and dc generator?
a motor Will do work by consuming power a generator is just the opposite
What is the difference between a DC motor and a DC generator Why can't you use a DC motor as DC generator?
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.
How do you change over a ac motor to a dc generator?
Type your answer here... how can you change an ac motor to a dc generator
How do you convert a DC motor to a 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
What are the differences between the parts of a generator and the parts of a motor?
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.
How do you make DC 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.
How DC generator is started?
by a hand driven motor or always it is connected with dc motor.
Can a motor works as a generator?
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.
How does the starting of synchronous motor using dc generator as a load work-?
Starting of the synchronous motor using the DC generator creates a magnetic field.
What are the differences between a car engine and a generator engine?
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..........
What is the best dc motor to use when building a wind generator?
A brush-less DC motor (BLDC)
What is the difference between DC motors and DC generator?
A generator turns mechanical (or other) energy into electricity. A motor does the exact opposite, turning electrical energy into mechanical energy (e.g. motion).
