Transformer & Electric Motor Working Principle same?

To the extent that both operate on the basis of fluctuating magnetic fields, they are the same. I'm not sure why that is supposed to be meaningful.

Please explain how a transformer generates shaft work.

Please explain how a motor can convert one voltage into another.

If these two items were the same, how come they have different name labels?

Electric motors convert electrical energy into work.. Electrical transformers convert electrical energy into different types.

Both transformers and motors work under the principle of electromagnetic induction.In the case of transformer both primary and secondary windings are fixed and hence induce voltage in secondary when voltage is introduced in primary winding depending on turns ratio. In the case of motors the primary is stationary where as secondary is free to rotate and when voltage is introduced in stator winding the free rotor rotate due to magnetic induction.

Basically they are the same at a root level only in that they operate on the principals of induction and mutual induction.

Nikola Tesla first described his AC motor as a rotating transformer. People still occasionally use motors as rotating transformers, if they need both functions and want only one device, or when one needs to transfer power across a rotating element. If you Google "rotating transformer" you will see information on that.

A "linear motor" is more akin to a standard transformer in that the only difference really is in that one side of it is free to move.

Simplified...

Transformers convert electrical energy into electrical energy.
(Vin * Iin) = (Vout * Iout) + {some loss as heat}

Motors convert electrical energy into mechanical energy.
(Vin * Iin) = (ω [radians/second] * T [N-m]) + {some loss as heat}

They both use electrical current to generate a magnetic field. The difference is how the resulting magnetic field is used. For transformers, the magnetic field is used to generate another current. For motors, the magnetic field is used to generate a mechanical force or Torque.

The transformer and induction motor works on the principle of Faraday's law of electromagnetic induction. The varying flux produced in the primary of the transformer gets linked to the secondary and voltage is induced in the secondary. In induction motor the flux produced in the stator gets linked to the rotor conductor and induce voltage in the rotor. The rotor of an induction motor is short circuited hence current starts flowing in the rotor. An interaction of the main flux and rotor current produces torque.

The difference between the transformer and induction motor construction is that the rotor of the induction motor is short circuited whereas the secondary of the transformer is open circuited.
