A transformer uses a varying magnetic field to induce a voltage in another winding, often changing the voltage to match the requirements of the load.
A motor uses a varying magnetic field in induce a torque in the armature, making it turn, converting electrical energy into mechanical energy. In the case of an induction motor, the "windings" in the armature are built in as "single turn shorted secondary windings", rather than windings connected via slip rings or commutators, but the end result is the same - opposing and attracting magnetic fields cause the armature to rotate.
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.
A transformer or, more-properly, a mutual transformer, has two windings, the primary and the secondary, which are electrically-isolated from each other, with the secondary voltage induced through mutual induction. An autotransformerconsists of one tapped winding, so the secondary circuit is not electrically isolated from the primary circuit. An autotransformer may be used to either increase or decrease the primary voltage, depending how it is connected.
Hi , It works on the principle that mutual induction between two coils.

It uses electromagnetic induction to transfer energy between separate circuits.
there is nothing like a balanced and unbalanced transformer.
Transformer in Hindi is called "ट्रांसफ़ॉर्मर" (pronounced as "transformer"). It is a device used to transfer electrical energy between two or more circuits through electromagnetic induction.
An auto transformer has one winding with the output being tapped at some point and therefore has no isolation between primary and secondary. This may make it unsafe or illegal in some applications. A common power transformer has separate windings.
Both are same. This is an instrument transformer used for metering & protections.
The 3 kVA transformer will weigh double the 1.5 kVA transformer.
In an induction motor, power is supplied to the rotor using a changing magnetic flux i.e. without any true conductive contact. Similarly, in a transformer, the power is transferred from the primary coil to the secondry one using a varying magnetic flux and the plates have no physical linkage. Hence, the similarity between an induction motor and a transformer is very basic i.e. they both use the phenomenon of electromagnetic induction to transfer power from one part to another.
An isolation transformer is usually a ferromagnetic transformer. The question needs to be framed more usefully.
