Difference between motor and generator is perhaps the foremost common question from the electricity topic of physics. during this article, the most variations between motor and generator square measure given here. The motor and generator distinction given here is in tabular kind for higher understanding and clarity.
Before moving to the variations between a motor and generator, it’s vital to understand what they’re. Their functions, structure and alternative connected details. to be told additional concerning an electrical motor and generator, visit the links given below.
In applied science, the foremost topic is Electrical Machine. The electrical machines accommodate the 2 major elements one is that the electrical motor and another is that the generator.
Both are magnetism Devices and works within the electrical energy (AC) and electricity (DC) system. however, they need some totally different functions, operating principles, operating rules, uses, etc.
I am sharing the ‘ during this tutorial by mistreatment the comparisons of the electrical motor and generator.
Rule: Electric motor follows Fleming’s left-hand rule.
Principle: Motors works on the principle that a current carrying conductor experiences a force when placed in a magnetic field.
Driving force for shaft: The shaft of an electric motor is driven by a magnetic force which is developed between the armature and field.
Current Usage: In a motor, current is supplied to the armature winding.
Example: Ceiling fans, cars, etc. are all examples of motor.
Rule: Electric generator follows Fleming’s right-hand rule.
Principle: Generators work on the principle of electromagnetic induction.
Driving force for shaft: The shaft of an electric generator is connected to the rotor which is driven by a mechanical force.
Current Usage: In a generator, current is produced in the armature winding.
Example: In power stations, the generator is used to generate electricity.
Electric generators: Converting mechanical energy into electric energy
According to Faraday’s Law of Induction, whenever there’s an amendment within the magnetic flux across a conductor, like a wire coil, electrons square measure forced to maneuver perpendicular thereto magnetic flux. This generates electrical phenomenon, that creates a flow of electrons in one direction. This development will be accustomed turn out electricity in an electrical generator.
To create this magnetic flux, the magnets and therefore the conductor square measure affected relative to at least one another. The wires square measure wound into tight coils, increasing the number of wires and therefore the ensuing electrical phenomenon. unendingly rotating either the coil or the magnet, whereas keeping the opposite in situ, provides continual flux variation. The rotating part is spoken as a “rotor,” whereas the stationary part is termed a “stator.”
Electric generators make up 2 broad categories: “dynamos,” that generate DC, and “alternators,” that generate electrical energy.
The generator was the primary type of electrical generator that was helpful for industrial applications. throughout the economic Revolution, it had been fancied severally by many individuals. the electrical generator uses rotating coils of wire and magnetic fields to convert energy into DC (DC). traditionally, dynamos were used for wattage generation, usually victimization steam as a supply to get the required energy.
Today, the electrical generator has few uses outside of a number of low-power applications. Alternators square measure much more widespread for electricity generation. this sort of generator converts energy into electrical energy. A rotating magnet is a rotor, turning at intervals a collection of conductor coils on AN iron core, that is the mechanical device. because the magnetic flux rotates, it generates AN ac voltage within the mechanical device. The magnetic flux will be created either by permanent magnets or by a coil magnet.
An automobile’s generator, additionally as central power stations that give electricity to a grid, square measure electrical generators.
Electric motors: From electrical energy to mechanical energy
An electric motor will the alternative of an electrical generator. rather than turning energy into electricity, an electrical motor takes electricity and converts it into energy. electrical motors will be found in an exceedingly numerous vary of applications, from industrial producing machinery to everyday home appliances. The rotor turns a shaft to form mechanical power. The stator coil is formed from coil windings or permanent magnets, with a core of skinny sheets bedded along. referred to as laminations, these layers produce less energy loss than a solid core. Between the rotor and stator coil may be a little air gap, that helps increase the magnetizing current.
Although electrical motors will be electricity, electricity, or magnetic, the overwhelming majority of contemporary motors use magnets. Some square measure designed to run on dc, whereas others use ac. you’ll be able to realize electrical motors of all sizes in an associate imposingly wide selection of applications. From little motors in powered watches to huge electrical motors that power industrial producing machinery, this strong however elegant piece of technology is central to fashionable life as we all know it.
