You wind a coil of wire around a metal rod(conductor). Then pass current thro the wire, a magnetic field will get induced.. This is solenoid.. something like an electromagnet .
Inductor is a coil of wire.. I dont think its wound around anything
dustrial Work Solenoid Application Considerations
Industrial work solenoids can be designed to accept attachment of the load to the pulling or pushing end of the plunger. For some applications the plunger assembly is designed to accept load attachments at both ends.
Properly designed and applied, a linear industrial work solenoid will generate forces sufficient to move the applied load through the specified stroke and in the specified period of time. It must do so under all specified operating conditions. The Industrial Work Solenoid Selection Guidelines section is provided to assist you in developing your application specifications
There are several issues that must be considered when any customer application is being reviewed.
The method of connecting the load to the industrial work solenoid must be developed with consideration in mind that side loads will be detrimental to industrial work solenoid life if not properly accounted for. Furthermore, if the installation causes a binding condition anywhere within the required operating stroke, excessive wear and reduced operating life will result.
Industrial work solenoid holding force typically suffers dramatically if the plunger is not allowed to come into contact with the stationary pole piece. If the industrial work solenoid will be required to generate a sustained holding force after it has moved the load through its working stroke, then, it most likely will be a requirement that the plunger seat itself is at the end of travel as opposed to being stopped by the load. There are exceptions to this general rule. They must be dealt with through detail application and design analysis.
Excessive force can cause its own set of problems. If under any operating conditions, the industrial work solenoid generates forces far in excess of what is required to move the load, then there will be excess kinetic energy developed in the plunger as it accelerates through its stroke. This excess kinetic energy needs to be dissipated in a manner that is not harmful to the industrial work solenoid or the mechanism it is driving. Trombetta can provide application assistance in evaluating and dealing with such situations.
Electronic controls often make practical what otherwise may not be a practical application. In other cases they can serve to optimize the design of the total system through shaping or stabilizing the performance of the industrial work solenoid, reducing its size or a combination of these factors. While controls are an added cost item, they can often offset other costs by reducing the size and cost of the industrial work solenoid required for the task and/or by simplifying the entire mechanism of which the industrial work solenoid is a component
solinoids follow the same prinicples of electro magnetic relays but the end application is slightly different. it is used to control fluids, gases, or can be used as lock which has a small elongated bar which is pulled to and fro by energising the coil.
