What Is The Difference Between An Alternator And A Generator

The armature rotates inside a stationary magnetic field.

Alternators cannot charge a completely dead battery whereas generators can charge a dead battery. Alternators have a rotating magnetic field and a generator has a stationary magnetic field which is fixed where the armature winding spins. Contrary to this the alternator only produces alternating current. A generator produces direct current dc and an alternator produces alternating current ac.

The alternators can t be used for charging the dead battery. An alternator is a machine which converts the mechanical energy from a prime mover into the ac whereas the generator converters the mechanical energy from the prime mover into an ac or dc. Key differences between an alternator and a generator 1 power output. An alternator always induces an alternating current.

Key differences between alternator generator. A generator can generate either alternating or direct current. A generator is an electric device that facilitates the conversion of mechanical into either alternating current ac or direct current dc. While both of these devices will convert mechanical energy to electrical energy an alternator will convert this energy into ac only while a generator can convert this energy into either ac or dc.

Alternators have rpm rotations per minute ranges and a generator offers a slight variation in the rpm range. The alternator induces the ac whereas the generator causes both the ac and dc power. Apart from that they are different from each other in every other aspect. Alternators conserve energy by using only the energy that is needed while generators use all the energy that is produced.

The power we use in our homes is ac yet we call the device that produces that electricity a generator. An alternator is a device that converts mechanical energy into ac electrical energy. Alternators are considered more efficient than generators. Their usage can even cause the burning of the battery.

In a generator on the other hand the armature or windings of wire spin inside a fixed magnetic field to generate electricity. Alternator and generator are both mechanical devices that convert mechanical energy into electrical energy. Alternators receive input supply from the stator and generators receive that input supply from the rotor. The electricity used in a car is dc yet we call this device an alternator.

The major point that differentiates between an alternator and generator is that in an alternator the magnetic field rotates around a stationary armature and in generator. A generator is a mechanical device which converts mechanical energy to either ac or dc electrical energy.
