A dynamo generator and an electric motor are similar in construction, but work in opposite ways to one another, and have reciprocal purposes. Both contain a central shaft with affixed magnet(s) surrounded by a series of wound coils enclosed by an outer casing having two electrical leads, one live and one neutral.
In a dynamo, an outside mechanical force such as the rotation of a cyclist's wheel spins the central shaft and magnets around. The magnetic force pushes and pulls electrons in the outer coils which creates an electric potential between the leads.
In a motor, an electric current is fed to the leads which pushes and pulls electrons through the coils. The coils become negatively charged then positively charged, cycling back and forth to the opposing and attracting magnets. This drives the shaft in a circle to power an external mechanical device.
Motor . . . Put electrical energy in, get mechanical energy out (the shaft spins).
Generator . . . Put mechanical energy in (spin the shaft), get electrical energy out.
Same machine can be used both as a generator and motor!!
the difference is given electrical energy a motor converts it into mechanical energy...for example the fan contains a motor which rotates when you switch it on..i.e.,when you are supplying electrical energy...on the other hand a generator converts mechanical energy into electrical energy..for example the dynamo in a cycle lights up the bulb when you are pedaling..
The basic difference between an electrical generator & electrical motor is the conversion of energy.
Principally, in case of electrical generator the mechanical energy (steam, water, wind) is converted into electrical energy whereas in case of electrical motor the electrical energy is converted into mechanical energy.
Electrical generators are used for generating electrical power while electrical motors are used to consume electrical energy to do some mechancial work eg. pumping water, moving elevators etc.
well the above answer provided by another fellow engineer
In generators though we provide mechanical energy we need to energize the field
and of course we've self excited generator.
where as in motors (AC) we provide suppy to the stator itself and suppy will be induced in rotors to get rotation
in DC stator and rotor is connected either in series or shunt. collectively we provide suppy to it
Generators change mechanical power to electrical power.
Motors change electrical power to mechanical power.
Permanent magnet dc motors and generators can usually work either way.
an electric motor converts the electrical energy into mechanical energy by rotation based on the principle of electromagnetic induction.
and electric generator converts the mechanical energy into electrical energy based on the same principle but works reversed.
In simplest terms -
(staying away from discussing residual magnetism & permanent magnets)
(1) If mechanical power turns the shaft, you will generate electricity from the wires. This is called generator action.
(2) If you put electricity into the wires, you will get mechanical power (rotation) from the shaft. This is called motor action.
The same (motor) can often be used either way. Hope that clears it up a bit.
1.A generator is an electric device that convert mechanical energy to electrical energy while an electic motor convert electrical energy to mechanical energy. 2. A generator have a carbon slip ring while an electric motor have a carbon split ring.
Generator is the device that generates electricity. Motor is a rotating device using electricity

The sizing of the generator is dependant on the size of the electric motor driving the mixer.
electric motor and electric generator
The amount of an electric motor's copper depends upon the size of the motor and the supplies used to make it. Generally, the older the motor, the more copper will be present.
A 15 KW generator won't likely run everything in your house, but besides that it is not efficient. You will be using more electricity to run the generator than the power would deliver. You also defeat the reason for the generator - run your house when power goes out. Now if you had a wind turbine turning a generator you have a positive contribution to house power. This is how wind power works. There are also lots of issues associated with a power transfer switch and feeding power back into the grid.
When current is induced in the rotating coil in an electric generator then a counter couple acts on the current carrying rotating coil in the magnetic field(in accordance to the principle of dc motor). This counter couple is called back motor effect.
electric motor
Electric Generator. :)
yes
An electric motor converts electrical energy into mechanical energy. While an electrical generator does the opposite.
The sizing of the generator is dependant on the size of the electric motor driving the mixer.
It has electric!

A generator.
a motor is a generator and a generator is a motor, if you are applying a voltage to turn the rotor its a motor and if you are turning the rotor and taking the voltage off the terminals its a generator or alternator.
I think it can work with a certain type of generator and an electric motor like one that uses 300w/h The idea is to run a generator that can produce more electricity than needed to run the motor that is powering it.
An electric motor converts electric energy to mechanical energy while a generator converts mechanical energy to electric energy.
