Engineers who are concerned with the design of various devices in all the industries are facing the ever increasing challenge of making the products with maximum efficiency while reducing the size of such devices to the minimum. Typically, design engineers are looking for deriving more power from a smaller device, which has a greater efficiency and also possesses a longer life. This is done in order to reduce the consumption of power and encourage simple usability in the case of handheld devices. This is where the use of small motors comes into the picture. In the present times, small motors find a variety of applications such as in surgical power tools, in medical devices, infusion systems, industrial power tools, clinical diagnostics, aerospace, and in the field of automation and robotics.
