Perpetual motion machines are an impossibility. Energy conversion is never 100% efficient. Even if it were, friction is never zero.

What describes a perpetual motion machine?

A perpetual motion machine is a hypothetical device that can continue to operate indefinitely without any external energy source. It violates the laws of thermodynamics, which state that energy cannot be created or destroyed, making the concept of a perpetual motion machine impossible.


How feasible is the development of a magnetic motor capable of achieving perpetual motion?

The development of a magnetic motor capable of achieving perpetual motion is not feasible due to the laws of thermodynamics, which state that perpetual motion is impossible.


How can an electric motor generator be designed to achieve perpetual motion?

It is not possible to design an electric motor generator to achieve perpetual motion because it goes against the laws of physics. Perpetual motion would require the motor to continuously generate more energy than it consumes, which is not feasible.


Why can't electric suppliers use electric motors to spin the generators?

If you are suggesting a "perpetual motion" scenerio, it would violate the first or second laws of thermodynamics. Many inventors dream of perpetual motion machines, but they are an impossible dream according to the laws of thermodynamics. The second law of thermodynamics says that an engine or process of any type must always have an efficiency of less than 100%. A perpetual motion machine that uses a generator to power the motor that runs the generator requires both the generator and motor to operate with 100% efficiency. This type of perpetual motion machine does not violate the first law of thermodynamics, but violates the second law of thermodynamics. It is a perpetual motion machine of the second kind because it violates the second law of thermodynamics. Not even the cleverest engineer or inventor can build a perpetual motion machine because it would violate either the first or second law of thermodynamics, which are fundamental laws of physics.


What AC motor is used in an escalator?

we can either use dc series motor or induction machine ,but dc supply is not easily available so we use induction motor ,


Can a motor works as a dynamo I'mean produce electricity?

Yes, but if you are asking if that configuration can be sustained, i.e. as a perpetual motion machine, the answer is no. There will always be losses associated with power conversion, and these losses make a perpetual motion machine an impossibility.


When Tesla suggested the AC motor his teacher humiliated him and said he was trying to create what?

Tesla's teacher said he was trying to create a perpetual motion machine, which was considered impossible at the time. Tesla's design for the AC motor, however, revolutionized the field of electricity and became the basis for modern electrical power systems.


If an alternator supplies electricity to an electric motor that spins the alternator will it run forever?

Yes, you could connect these parts together and it would operate. But after awhile you will find that the batteries are running low and the will motor is run slower than initially. The answer to the specific question is "no - you could not do this to generate electricity endlessly". If you could, that would constitute a perpetual motion machine, and that is impossible to do, due to losses in energy conversion because nothing is perfectly efficient.


Are the friction losses of the machine linear in induction motor electrical machines?

yes


Is there a perpetual magnetic motor called the HOJO Motor with enough torque to drive a residential household generator providing free household electricity?

There is a HoJo motor which is 'claimed' to be a perpetual-drive motor -but, in reality, there is no such thing as perpetual motion. And it most certainly wouldn't drive a generator capable of supplying the energy needs of a residence! In short, it's a scam.


What is an Induction Machine?

An asynchronous alternating-current machine, such as an induction motor or induction generator, in which the windings of two electric circuits rotate with respect to each other and power is transferred from one circuit to the other by electromagnetic induction.Reference: Wiki Answers
