Electromechanical Assembly

What exactly is an electromechanical assembly? The technical definition is any device that uses electrical current and transforms it into an operation that performs some type of work. The most common type of electromechanical device is the common relay. This device uses electrical current to energize an electromagnetic which then causes a switch to open or close depending on the design. Engineers use these simple devices to turn circuits on and off as needed. In some cases the relay is used to switch higher current circuit than the sensor operating the relay can carry. A perfect example of this type of electromechanical assembly in use would be one of today's automobiles. All of the cars made today have at least one if not two electric fans behind the radiator; these fans are turned on and off by a temperature sensor in the car's engine cooling system. The fans however draw far more current than the wires coming from the sensor can carry. To prevent overloaded wiring, the manufacturer routes the sensor to a relay which it activates and turns the fan on. The relay carries the heavier current load keeping everything working safely. Another common form of electromechanical assembly that is used in many pieces of expensive electronic equipment is the overload protection relay.

This simple device can save a multimillion dollar piece of equipment from being damaged in the event of a circuit overload. Often seen in electric motors this unit is designed to shut the system down if the operating temperature of the electric motor becomes too high. This device consists of a pair of bi metallic strips that release a spring holding the power contacts together when they get too hot. When an engineer designs a new electromechanical assembly he starts out with a need to create a device that performs a certain task. With this in mind he will sit down with his pad and paper or CAD software and take the idea as far as the concept drawing. Most engineers then turn to a company that has experience in building electromechanical devices for further research.

The company he goes to will turn the design over to their engineering department for a feasibility study and to let the designer know what it will cost to build. Once the go ahead is given to build a prototype electromechanical assembly, the company's engineers will create a full size working model of the device for further study. During this process a detailed report is prepared that explains what materials are used and the assembly process that will be needed should the designer wish to go into production with his new device. At JEM Electronics you will find a fully staffed engineering department that has the experience and knowledge to take a rough draft or detailed schematic of your electromechanical assembly and create a working prototype. If the device turns out to the way you planned they can help you further by providing you with full manufacturing capability and to ensure quality test every product they manufacture.
