Differbetween
An alternator is a device that converts mechanical energy into AC electrical energy. A generator is a mechanical device which converts mechanical energy to either AC or DC electrical energy. An alternator always induces an alternating current. A generator can generate either alternating or direct current.

Main Differences between Alternator and Generator
| Alternator | Generator |
|---|---|
| It can only generated Alternating Current “AC”. | It can generate either of both Alternating current AC or Direct Current “DC”. |
| The rotating part or rotor is the magnetic field. | The rotating part or rotor is the armature. |
What is the difference between alternator and dynamo?
An alternator is a device that generates AC power from the rotation of an axle (mechanical energy). They are a bit similar to dynamos, but differ in the fact that they make AC power, whereas dynamo's generate DC power. In addition, they also tend to be more efficient.
Do cars have alternators or generators?
An alternator is a type of electric generator used in modern automobiles to charge the battery and to power the electrical system when its engine is running. ... As silicon diode rectifiers became widely available and affordable, the alternator gradually replaced the dynamo.
What is the difference between alternator and synchronous motor?
Definition: The synchronous generator or alternator is an electrical machine that converts the mechanical power from a prime mover into an AC electrical power at a particular voltage and frequency. The synchronous motor always runs at a constant speed called synchronous speed.
Are alternators AC or DC?
Car batteries operate on one-way direct current (DC) electricity, while alternators output alternating current (AC) electricity, which occasionally flows in reverse.
What is a 3 phase alternator?
Three-phase alternators have three sets of windings; they're more efficient than a single-phase alternator, which produce a single-phase AC current. When working properly, the three windings produce three currents that make up the three phases. Adding all three together produces the total AC output of the stator.
Is a dynamo AC or DC?
A dynamo is an electrical generator that creates direct current using a commutator. ... It is basically a DC generator, i.e. an electrical machine which converts mechanical power into direct current electrical power.
What is difference between alternator and generator?
An alternator is a device that converts mechanical energy into AC electrical energy. A generator is a mechanical device which converts mechanical energy to either AC or DC electrical energy. An alternator always induces an alternating current. A generator can generate either alternating or direct current.
How many volts can a dynamo produce?
Each dynamo is capable of producing 24v that can be used for low power application . So here in electrical cars the dynamo role is that the car has four wheels so in each wheel we can place one dynamo so from each dynamo we can get 24v when these dynamos are connected in series we can get the output of 96v.
Why DC is not used in homes?
The answer to why DC current is not used in homes goes back to the inherent characteristics of direct currents and their weaknesses compared to Alternating Currents (AC). In fact, AC currents can be easily transmitted over long distances without much loss. They are also safer in direct touch at an equal voltage.
Does a car run on AC or DC?
Cars use DC, Direct Current. That's the type of electricity produced by batteries, and it flows in one constant direction. It's also the type of electricity produced by a generator, which was used in automobiles from the early 1900s up until the 1960s.
What causes an alternator to fail?
Bad diodes are a common cause of alternator failure. The diodes are part of the rectifier assembly that converts the alternator's AC output to DC. ... A leaky diode also can allow current to drain out of the battery through the alternator when the vehicle is not being driven.
