What is the difference between transformer and generator and motor?

A motor is a machine that converts other forms of energy into mechanical energy, therefore creating motion.
A generator converts mechanical energy into electrical energy via the method of magnetic induction.
You should probably check up Michael Faraday and Lenz. Or maybe look in a HSC Year 12 text book like Jacaranda.

∙ 12y agoA transformer converts voltage and current to different values, but keeps input power equivalent to output power (minus some small value of losses). Thus the input to a transformer is electric energy, and the output is electric energy of about the same magnitude.
A generator takes kinetic energy and converts it into electric energy.
A motor takes electric energy and converts it into kinetic energy.

Difference between a generator and a motor?
A generator converts kinetic energy into electrical energy; a motor converts electrical energy into kinetic energy.
What is the problem with using an electric motor to run a generator stepped up with transformers that is used to run the motor and give electricity for other uses?
It's all to do with the conservation of energy. The output power of the transformer cannot be greater than the input power from the motor used to drive your generator! In fact, it will be significantly lower than the power of your first motor due to the efficiency of the motor, of the generator being driven by that motor, and of the transformer. So if you then try to run the original motor from the output of your transformer, the energy-losses will simply accumulate, and the motor will not be able to run!
Why Back EMF occur in only dc motor?
It doesn't. It exists in all electrical machines, d.c. or a.c., motor, generator, or transformer.
Will using a transformer to convert 230V to 12V DC consume more energy than using a few capacitors and resistors without a transformer?
no, the transformer is much more efficient <><><> HOWEVER- a transformer only changes the voltage of AC current- it does not change it to DC. You will still need diodes or rectifiers. You can also use a motor/generator- a 230v AC motor turns a 12 v DC generator.
Difference between synchronous generator and synchronous motor?
ASYNCHRONOUS is a mode whereby events happens irregardless of control. SYNCHRONOUS are this same events but controlled by a timing and/or control
Difference between a generator and a motor?
A generator converts kinetic energy into electrical energy; a motor converts electrical energy into kinetic energy.
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 electricmotor and generator?
An electric motor is an AC motor which works with alternating current But Generator is D. C motor that works under the principle of direct current
Difference between transformer and induction motor?
1. Induction Motor has an air-gap but transformer has no air gap rather it is mutually link. 2. Induction Motor has high no-load current than transformer. 3. Induction Motor is a dynamic device. 4. Induction Motor has high power factor.
What is a static transformer?
It's a transformer that operates with AC current in and out. It's an ordinary transformer, with the term "static" used to differentiate it from rotating transformers, such as motor-generator sets.

Which device you use to increase voltage from 220V to 11000V?
If it is AC, a transformer. If it is DC, a motor generator.
What is the difference between an electic motor and an electic generator?
AC motor produce mechanical power and absorbed electric energy the power generator produce electrical power absorbed mechanical power
What is the difference between a electric motor and a generator?
the difference between a electric motor and a generator.Motor- is a device or equipment which convert electrical energy to mechanical energy.Generator- is a device or equipment which convert mechanical energy to electrical energy.

It doesn't. It exists in all electrical machines, d.c. or a.c., motor, generator, or transformer.
How do you calculate amount of copper used in a motor AC or DC and generator and transformer Datasheets do provide power rating and mass of the equipment can we somehow use this available info?
One thing you could do is look up the datasheet for the motor and/or contact the manufacturer of the motor. Also, if you know the guage of wire, you can calculate it based on the resistance of the coils on the motor/generator or on the coils of the transformer
