Difference Between Electric Motors and Generators

Generator and Motor are two distinct gadgets with various applications. A generator is a more extensive term used to characterize a machine which produces power. We will center around the capacity of a specific component of a power generator called the alternator.


Actually, it’s the alternator which takes every necessary step of delivering power. Then again, an engine is a gadget which is utilized for siphoning water. Be that as it may, an engine can be utilized for some different uses and applications.


Only for purpose of observing, let’s get straight to the point by and by that the expression “generator” is a more extensive term and for the setting of the current article it is really the working of an alternator that we are alluding to when we utilize the expression “Generator”.

Additionally to be noted before we proceed to comprehend the distinction between a generator and an engine is the way that engines and generators are accessible in both AC/DC variations. We would remember this reality while proceeding with the article.


The basic premise of construction for both a generator and engine is Faraday’s law of Induction. (Faraday’s Law of Induction: The actuated electromotive power in any shut circuit is equivalent to the negative of the time rate of progress of the attractive transition encased by the circuit. Source: Wikipedia).

Generators and motor both have current conveying circles which are turned in an attractive field. The circles are folded over an armature. An Armature is comprised of iron center henceforth here the attractive field turns out to be really solid. The bearing of the current in the circles is then turned around bringing about development. This movement makes what is called EMF or electromotive power. Thus changing over one type of vitality into another. For this situation mechanical vitality to electrical and the other way around.

Give us now a chance to consider the contrasts between a generator and an engine


  1. Mechanical vitality is used to cause movement in the loops.
  2. EMF produced is sine wave shifting with time.
  3. The course of the current delivered is represented by fleming’s correct hand rule
  4. A shaft and rotor system is utilized which is driven by mechanical power.
  5. Armature winding is the point from where the electric flow is emitted.
  6. A generator attributable to its operational structure needs more maintenance.


  1. Electrical vitality is used to cause the movement in circles.
  2. Induction is utilized for this situation.
  3. The heading of the current created is administered by Fleming’s left-hand rule.
  4.  Here the mechanical power is produced by the development of the pole because of associations between the field and the armature.
  5.  Here the power is provided to the armature winding, which results in the task of the engine.
  6.  A motor requires insignificant upkeep.
