What type classification would a motor with copper bars in the rotor fall into?

although this is not a chemistry question I do have an answer for you. A motor with copper bars is classified as a shaded pole motor. They are low torque motors and do not require any capacitors for run or start functions. hope that helped

Would copper melt in acid?
Only if the acid is above the melting point of copper. However, the copper might dissolve in acid if the acid is oxidizing. If it did, copper ions would be present in the solution formed, but there would not be an metallic copper in it.
What are copper nails made out of?
I would assume copper
What is would you expect to see when zinc is added to Copper Sulphate?
there would be a single replacement reaction where the copper forms on the top of the zinc and the blue color of the copper sulfate would get lighter and eventually you would end up with zinc sulfate and copper
Why all of the winding and even the commutator of motor are made of copper?
Copper is the best base metal for conducting electricity. Gold and silver are better but too expensive. If you used a poorer metal you would lose more power and it would also generate more heat which in a motor would be quite a lot u also familiar with Cu loss-.5 v it is helpful to less the voltage drop at winding and any placed there was used Cu.

What is locked rotor?
Locked rotor current is the amount of current a motor would draw if you energize the motor and the rotor (the spinning shaft) doesn't spin.
Can the position of the rotor and stator in an AC motor be inverted?
In principle they can be exchanged but the result would be a more expensive motor. Imagine an induction motor with the AC applied to the rotor. That would need slip rings and brushes which would need replacing now and again. All the customers would go for the other sort with the AC applied to the stator and a simple squirrel-cage on the rotor.
Why is it not possible to insert the external resistance in the rotor circuit in a cage induction motor?
A squirrel-cage rotor consists of uninsulated copper or alumnium bars, short-circuited by rings located at opposite ends, and semi-enclosed within a laminated iron rotor, and there is no provision for any form of external connection. So it would be quite impractical to do what you suggest.

What will happen if the field of dc motor motor is opened?
Assuming a shunt-fed motor, it means the rotor would stop generating a back-emf and it would also stop generating any torque. The current would rise until limited by the resistance of the rotor, but before that the circuit-breaker would operate.
Can an alternator be converted into an ac motor?
It should be able to but I cannot say how efficient it would be. One would likely need to remove the electronics and have direct connections for the field windings and the rotor. Without rewinding the alternator, it would need to be fed with three phase AC power to the stator and DC to the rotor. Connected as described above, would result in a synchronous motor rather than an induction motor. If the rotor connections were shorted together the motor could possibly function as an induction motor.
What current would be drawn by a 15KW 400V AC motor with a locked rotor?
yes

Can a ge 36volt motor be run on 48 volts?
The 36 volt motor will over heat (depending on the load of the motor)on 48 volts and melt the copper inside the motor you can rewind the copper inside to cope with the extra 12 volts.My answer would be not to try it as i have and it totaly melted the copper inside.
Why does the rotor of an induction motor turn slower than the revolving field?
In an induction motor the rotor currents are induced by the magnetic field of the stator, and if the motor were to run at synchronous speed the induced currents and also the torque would fall to zero. The rotor currents alternate at a low frequency determined by the 'slip', which is the percentage amount that the rotor speed is below the synchronous speed. The output torque is proportional to the slip at near-synchronous speeds.
What is the scientific name or taxonomic classification of the bird Copper pheasant?
The scientific or taxonomic name would be Syrmaticus soemmerringii.
What happens if the rotor in an induction machine is replaced with an iron cylinder?
Nothing. The motor won't run because you would no longer have the counter-acting magnetic field from the induction windings in the rotor.
