Abstract
Recently, there has been a rapid expansion in the area of micromotors that can control or simply move mechanical parts in a particular direction. Typical examples of such micromotors include linear stepper motors, which can transform rotation into linear movement. Motors like these are applied in cars for changing the directions of headlight bulbs so that they follow the same direction as the wheels are turned, or motors for moving car seats to a desired position, or adjusting the angle of the seat or the position of the car mirrors, etc. In short, this type of micromotor can be used wherever there is a need for computer-controlled positioning. Lately, these small motors have begun to play a role in medical applications. Due to difficult conditions of use (varying high temperature, vibration, aggressive media, etc) and the miniaturisation, it is important to use the best materials in terms of magnetic and mechanical properties. Therefore, the motors should be made of the best available materials as well as with new design approaches for the chosen application. A new linear stepper micromotor will be developed. For this reason, new materials' developments and new technologies, like two-component injection-moulded permanent magnets and compressed soft magnetic composites will be applied. In addition to the magnetic properties of materials, it is also important that they are compatible with other structural materials. We will also focus on these aspects, and surface-hardening treatment in order to increase the lifetimes of the mechanical parts will be considered. As well as commercially available materials, we will also produce our own magnetic materials by the use of rapid-solidification techniques in order to obtain nanocrystalline materials that will give us the best magnetic properties. The parameters of manufacture will be studied and some procedures and technology will be additionally optimised. We expect that the results of the project will be new, innovative technologies for the preparation and treatment of materials and innovative design solutions for a new motor that will lead to higher magnetic fields (more torque) and also longer lifetimes (better mechanical properties, better wear resistance and higher temperature stability).
