The word solenoids got its birth from the Greek word “solen” which signifies a pipe or a channel. The second part of the name is coined from “edios” which is also a Greek word signifying an outline. Basically, it's an electrical component having a pipe-like structure. There are a large number of solenoid designs available that are used in many devices. Every one of them has their very own characteristics that make it valuable in the equipment they are used. Though they are available in several forms still all of them have the same working principle.
A solenoid is a simple electrical component that consists of a metallic core with a coil of wire winded around it. Whenever a current is passed through the solenoid, a continuous and uniform magnetic field is generated inside it. One of the most important things to note about a solenoid that produces a uniform magnetic field is that if its length is immeasurable then the strength of the field is the same throughout the element. Thus a solenoid can be used to do a large amount of work with a minimal amount of force generated due to an electric current.
Types of solenoids
As said earlier, there are several solenoids present in the market. They come in different design, materials and has diverse functions. Let's have a look at some of them.
Linear solenoids are enabled of using a push or a pull force on mechanical gadgets. It has found its use in diverse devices. For example, the started device of an automobile which has a motor in it. The best place where this solenoid is popular is in the electric lock. When the jolt is appended to the electric lock on an entryway, it can promptly secure the door by holding up a great deal of savagery and violence.
A DC C-Frame solenoid operates on a single frame, shaped like the letter ‘C’, which is winded by the coil. Though they are made to be used in a DC configuration but still can be designed to work with AC power. This type of solenoid has a broad range of use in various applications.
A DC D-Frame solenoid comes with 2-piece frames that are winded around by the coils. Like the DC C-Frame solenoids, these solenoids can also be formed into AC alternatives. These types of solenoids are mostly used in industrial applications.
An AC laminated solenoid is popular for their force that they generate during their first stroke. You can get them in a number of different configurations and specifications. These categories of solenoids will deliver a perfect buzz when they are being utilized.
Unlike other solenoids as discussed above, it has got a disc in it. The body consists of grooves and the presence of ball bearing makes motion easier. Initiating the solenoid makes the core to get drawn back into the coil. The force that is generated is then converted into rotational force which moves the disc. Nowadays this device is used in industrial environments.
We hope that you have got a good idea of solenoids. Brands that produce solenoids are Crouzet, TE Connectivity, and Littelfuse. Refer to them using the links as provided. Thanks for reading.
