Miniaturization of Electrical Machines

“Less is more”, a popular saying of our time, but what most people don’t realize is the fact that the greatest minds of our age have turned this into their mantra and are pushing the boundaries of modern innovation by keeping to this simple aspiration. The most ambitious bunch following this motto are the electrical engineers, who are making major strides towards creating the next generation of electric devices and miniaturization of these devices is the major design element that they are focusing on.

The need for miniature parts of electronic machines stems from the fact that many machines and devices are being miniaturized in their design and structure. There is also the cost factor involved, smaller parts mean a lower manufacturing cost. There are a myriad of fields that are benefiting from producing tinier, efficient and more affordable machines.

The Race for Smaller Machines

The most important industry, regarding miniaturization of machines, is the aerospace industry. The requirements for modern flying machines, especially rockets, encouraged the creation of components that were considerably lighter and smaller than the ones that were utilized in the past.

By far the ‘giant leap’ in the miniaturization of electrical machines was the invention of semiconductors. Next step, integrated circuits; and the rest is a beautiful history that helped us assimilate hundreds of transistors in the most minuscule of circuits. When the PCBs (Printed Circuit Boards) became the norm, the sensors and inductors used on them needed to be smaller, this requirement also helped push the production of miniaturized electrical machine components and eventually machines.

The Medical Industry

The industries mentioned above were the ones that brought the miniaturization process into the fast lane and benefited from them the most. But the industry that was completely revolutionized by this trend was the medical industry. A few decades ago, placing an electronic device inside a human body was impossible, but now, thanks to miniaturization of electrical machines, we can even place a ‘Tony Stark’ like pacemakers inside human beings.

The pacemakers of yesteryear were bigger than most Smartphones today, imagine fitting your Smartphone inside your chest cavity; that would be impossible to say the least. Thanks to the smaller components and the miniaturization movement, the pacemakers are now roughly the size of a large coin and slightly thicker. They allow heart patients to lead normal lives, without having the fear of damaging their pacemaker.

The Modern Gadgets

Any discussion about miniaturized electrical machines would be incomplete without the mentions of the modern smart-devices. From cell phones to smart watches, every gadget out in the market was made possible because an electrical engineer somewhere created smaller components for them. And the amazing thing about these gadgets is that the reduction in their size still continuing, with each newer model being smaller and lighter than the last one.

Research and Development

If the latest technologies around us are any indication, the research into miniaturization of electrical machines growing and reaching further than we first thought of. Human curiosity is the driving force behind the R&D related to the miniaturization of electrical machines. The need to produce more efficient and popular devices is the reason why components like planar transformers are reducing in size.

Tech and electrical giants such as www.dualtec.co.uk, are also focused on reducing the manufacturing costs of their machines, and what better way to do it then creating smaller components and that help them create sleeker machines. The smaller the component, the less manufacturing material the companies have to purchase; which means more profits for them and more striking devices for their customers.

Other industries aren’t focused on the cost but the utility that the smaller machines can offer them. The medical industry is a prime example. Devices like micro cameras are used because they can perform a function, which cannot be completed without the help of this miniaturized machine.
