Are any generator that produce dc current without brushes or commutator?
So all needs commutator?hutchphd said:I don't know of any off the top of my head. Is this a theoretical musing or a more practical inquiry?
Practical Inquiry
There are AC generators without brushes. Please: why do you want to know?Quix270 said:So all generator are ac but some have commutators or rectifiers to produce dc?
The very first generator, or dynamo, was made by Michael Faraday and gave a DC output. It did not have a reversing device (commutator) but it did have one rubbing contact. It can be seen in his laboratory at the Royal Institution, London.Quix270 said:Are any generator that produce dc current without brushes or commutator?
A DC generator without brushes and a commutator is a type of electrical generator that converts mechanical energy into direct current (DC) without the use of brushes and a commutator. It uses a different type of technology, such as permanent magnets or electronic switches, to produce DC power.
A DC generator without brushes and a commutator works by using a stationary set of permanent magnets and a rotating set of electromagnets to create a magnetic field. As the electromagnets rotate, the magnetic field changes, inducing an electric current in the stationary coils. This current is then collected and converted into DC power.
There are several advantages to using a DC generator without brushes and a commutator. These include improved efficiency, reduced maintenance, and longer lifespan due to the absence of mechanical parts that can wear out. Additionally, these generators can be made smaller and lighter than traditional generators, making them ideal for portable applications.
While there are many benefits to using a DC generator without brushes and a commutator, there are also some limitations. These generators are typically more expensive to manufacture and may require more sophisticated control systems. They may also have lower power output compared to traditional generators, making them better suited for smaller-scale applications.
DC generators without brushes and a commutator are commonly used in portable electronics, such as laptops, cell phones, and handheld power tools. They are also used in renewable energy systems, such as wind turbines and solar panels, as well as in electric vehicles. Additionally, they can be found in industrial applications, such as conveyor systems and manufacturing equipment.
