Abstract
Induction motors with a planetary gear are a viable option for the transportation industry as they are a relatively inexpensive electric drive solution. Designing a prototype of a high-speed induction motor with a planetary gear is the focus of this project. This will be the proof of concept, to demonstrate a compact and cost-efficient electric drive solution, when compared to electric drives with lower speeds and no gearbox. Using a high-speed electric motor and gearing it down will provide a high torque density and power. A prototype with a high power density and efficiency will provide a competitive alternative to other electric drive solutions. The design choices of the prototype are covered. 3D modeling software is used for the mechanical design that integrates the planetary gear and the induction motor. Finite Element Method (FEM) simulations are completed to determine the final design. The geometry and properties of the induction motor are optimized using FEM. Electromagnetics, torque, and the losses of the induction motor are analyzed. The prototype design presented in this thesis is analyzed to determine the overall efficiency, cost, and feasibility for the transportation industry. The design allows for future development by ensuring easy changes and additions that can be made to the prototype. The development of the high-speed motor should continue with the use of models and design presented in this thesis. The design presented in this thesis is another step towards the final prototype production. The possibilities for future thesis topics and improvements will be discussed at the end of this thesis. One possibility for future development is the use of additive manufacturing to build the induction motor.Description
