<div class="section abstract"><div class="htmlview paragraph">In this paper, the study of plastic bonded magnetic material is studied for the surface adhesion of the material on to the surface of a metal cup. The bonded magnetic material is formed as a mixture of plastic material blended with ferrite or NdFeB Magnetic powder. The amount of magnetic material used is confined to the magnetic property of the magnetic powder that can exhibit the required magnetic performance as higher rotational speed and higher temperature. The magnet is injection moulded onto the outer circumference of the metal cup. The magnet is bonded onto the metal surface which is of cup shape and this assembly is magnetized to form a multipole magnet. This multipole magnet is designed to withstand high centrifugal force during the magnet rotation at higher rpm say 40000 rpm. For improving the adhesion properties with the two dissimilar material, the plastic bonded magnetic material and metal cup with zinc plating, the design on the metal cup is probed in detail and simulation has been carried out using FEA software. The adhesion of this two material binding is to be confined and confined to the properties of the plastic material in the mixture of the plastic bonded magnetic material.</div></div>
<div class="section abstract"><div class="htmlview paragraph">Belt-driven starter generator claw pole electric motors are used in hybrid automobiles to start the engine, charge the battery and to power the electrical system when its engine is running. Shaft and claw pole are important components in the claw pole electric motor. The claw pole is fitted onto the shaft through press-fit force. Press-fit is a widely used fastening process to join two different components by pushing a component inside or over another component with high press force which will create a strong bond between the components. Determining press-fit force required to assemble parts is very complex since it depends on a lot of factors such as mechanical material properties of components, interference fit condition whether it is in Min, mean and max condition, amount of contact pressure induced by contact surface, co-efficient of friction created in between components. The press-fit will help to prevent loosening components from its bond at high torque and speed. More over prediction of press-fit force is required to select pneumatic/hydraulic press machine capacity and to freeze the standard operating procedure in the assembly line. In this journal, the required shaft and claw poles press-fit force predicted to assemble for Min, mean and max fit condition by adopting contact non-linearity and material non-linearity technique in Finite element analysis (FEA) using Ansys Workbench and compared the FEA calculated results with theoretical calculation, physical measurements.</div></div>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
