What devices transformer electrical energy into mechanical energy?
An electric motor, such as a starting motor
What is the name of a step-up which increases the voltage of electric energy that is generated at a power?
An electrical transformer can step up (or step down) the voltage.
How demagnetize an electric motor?
A transformer winding only produces a magnetic field when current flows through it. Switch the current off, and the magnetic field disappears. You do not need to 'demagnetise' a transformer winding.
Name of the first electric motor?
The first electric motor was the Faraday Motor, invented by Michael Faraday in 1821. This motor was a very rude motor, you have motion from electric energy, but no useful work. In 1831 he discovered electromagnetic induction and invented the first induction motor. See links below for more info.
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!
What is goodness factor?
Goodness factor is a metric developed by Eric Laithwaite to determine the 'goodness' of an electric motor.
How many watt transformer is needed for 2.5 amp motor?
Need to know the voltage of the motor and primary voltage of the transformer.
What is earthing of electric motor?
This is avoided by grounding the motor frame. Both methods effectively produce a solid electrical connection straight to the stator laminations, allowing any insulation failure to be grounded via the end-ground user's conductor. Earthing is a technique in preventing electric shocks. To start, virtually all electric motors require grounding. The neutral earthing is given in the generator, transformer, motor, and other electrical devices by connecting the non-current carrying section to the neutral earthing.
What is the function of an electric motor in terms of electric power and motor?
The electric motor changes electric energy into mechanical energy.
What changes electric energy into motion?
An electric motor
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.
Why is a motor rated in KW's and a transformer rated in?
The mechanical load of a motor determines the necessary output power rating of an electric motor. As mechanical loads are defined in terms of watts (or, in North America, horse power), then motor's output must be rated in watts, too.The so-called 'power' rating of a transformer is determined by the rated voltage and the rated current of its secondary winding. The product of these two quantities is the transformer's rated 'apparent power', expressed in volt amperes.Incidentally, the symbol for "kilowatts" is "kW", not"KW's"!
