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

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.
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
Will a motor powering a altenater feeding a battery feeding an inverter power itself?
Nope. Nice try though. Folks have been trying to do this as long as there have been machines. Do a Google search for 'perpetual motion machine' and you'll see what I mean.
What describes a perpetual motion machine?
A motor that requires no energy input once it is running
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.

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
Why direction is clock wise of 3 phase induction machine?
It depends which side of the motor you are looking at!
Does induction motor works on Electromagnetic induction?
Yes the Induction motor works on Electromagnetic induction principle.

What is the name of a machine that changes electrical energy into energy of motion?
A motor
