what is the difference between D.C Motor and D.C Generator?

Answer 1

hi, your dc motor works(turns) when you apply electricity. The more power you introduce the faster it turns. Whereas the generator is turned by an external force example a small gas engine. It will produce a constant amount of voltage at a constant rpm. hope this helps;) good luck.

Answer 2

Motor needs an external power source, like electricity to turn and produce work (Workforce) to do it's intended purpose.
Generator produces electricity. It needs an external power source to do the purpose (Work) of producing electricity. We may use Fuel Engines, water, nuclear etc. to turn the generator to produce work.
Example of a motor is a Trolling Motor. We connect to a battery to produce thrust (work) to move a boat.
Example of a generator is those portable generators we use camping or to run our house when there is a power outage. It is connected to a gasoline engine to produce work.
Now with all this said; The first answer makes an interesting observation. A motor can act as a generator. Take two 12 VDC computer fans or if you wish use House fans that use AC. Face them toward each other so one will blow and make the other fan spin. Take a volt meter set to AC/DC depending which type fan you use and measure the voltage output of the fan that not connected and being turned by the other fan. You will see that the fan is considered a motor, but, when it is turned by an outside power source it also becomes a generator. It may not be as efficient, as this was not it's intended purpose.

Answer 3

Let us take a DC generator The generator has a driver say a diesel engine rotating an armature inside of a field. The self excited shunt generator the field is connected in parallel with the armature and the voltage output is taken from the armature brushes.The armature rotating inside a magnetic field creates EMF (voltage) The DC motor a voltage is applied to the armature brushes and the field in a shunt motor is parallel to the armature. The armature rotates inside the magnetic field. The magnetic fields between the field and the armature cause mechanical motion. So a generator mechanical motion creates electricity and a motor electricity creates mechanical motion.

Answer 4

D.C Generators produce the electricity that D.C Motors need to function.

Answer 5

Dc Motor And Dc Generator

Answer 6

In some cases they are identical/the same unit. With two sets of windings, a DC "motor-generator" is used to start an IC engine. Once the engine reaches operating speed the motor-generator generates output to charge the battery. They're quite common. AC Delco was probably one of the larger manufacturers.

Answer 7

Both are simply opposite.

First of all a motor is any thing which produces mechanical energy with electrical energy intake and Generator is Vice-versa. It produces electrical energy with mechanical energy intake.Both are in same principle of induction but in opposite direction.

Few appliances work on AC and few on DC(Alternative current,Direct current). AC has two levels to fluctuate i.e Positive and Negative where as DC has only one value to speak with,either positive or negative.

Now DC Motor "needs" DC charge to operate and DC Generator "produces" DC charge as the output.

Answer 8

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

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

The motor uses the supplied current to excite the fields which cause rotation and a shaft is powered to turn and do work.
In the generator, external mechanical force (such as the drive belt on a car turning the pulley on the alternator) is applied to turn the shaft which excites the fields and allows current to be drawn off and provides power for work.
One uses elect. Power to provide force, while the other uses force to produce elect. Power.

DC motors convert electrical energy into mechanical energy, while generators convert mechanical energy into electrical energy.

Answer 10

Nothing really. They both work off the principle of induction.
