Abstract

In the current state of the world, we are facing a growing number of problems climate change, resource depletion, air pollution, overpopulation and more. In this context, there is a growing urgency to transition to cleaner and more sustainable energy sources. Electrical motors play a critical role in the conversion of electrical energy into a mechanical one, making them a key component of this transition. These days, electric motors are in use everywhere from industrial machinery to electric vehicles and household appliances. Where, conventional bearings in electric motors have limitations such as friction, wear, and maintenance issues. Bearingless electric motors have emerged as an attractive alternative to conventional bearing motors as they can provide a maintenance-free and high-performance solution for various applications. Thus, a significant amount of researchs and developments has been conducted on electric motors with bearingless technology since they can operate without the use of traditional bearings to support the rotor. Instead, these motors use magnetic levitation or other forms of electromagnetic forces to suspend the rotor in the stator. This Master's thesis is part of a study on the replacement of traditional fan motors by these new bearingless motors. This will lead to a number of choices being made, taking into account a number of imposed factors, which will help to orient the approach.
