A Spherical Induction Motor with Hexahedron Stator for Attitude Control

获奖作品摘要

This study aims to design and fabricate a Spherical Induction Motor (SIM), which can provide a 3 degree-of-freedom angular momentum with only one motor and serve as the customized reaction sphere of Attitude Control System (ACS) in robots. Nevertheless, the efficiency of a conventional SIM is not only less than 20% but is also too complicated to be manufactured. To improve the efficiency and simplify the fabrication of a SIM, we design a hexahedron type stator, which requires only one molding die for fabrication and 3 pairs of power transistors for driving. The magnetic circuit analysis, equivalent circuit theory, Finite Element Analysis (FEA), prototype and the measurement of steady state speed and friction torque are implemented to assess the ratio of mechanical energy output under different input voltage and frequency. The FEA indicates that the efficiency of SIM can reach 89% and experiment reach 66% under ideal condition. Additionally, the steady state speed of prototype verifies the accuracy of design procedure. Finally, the mathematical model for SIM is constructed, which allows us to optimize its efficiency by setting the expected maximum angular momentum, input voltage and dimension. In conclusion, the manufacturing procedure of SIM with hexahedron stator is simplified, while the efficiency of SIM for attitude control can be increased. The mathematical model is effective and accurate for researcher to customize a SIM.

学科简介：工程力学 Engineering Mechanics

Studies that focus on the science and engineering that involve movement or structure.  The movement can be by the apparatus or the movement can affect the apparatus.

Subcategories:

Aerospace and Aeronautical Engineering (AER): Studies involving the design of aircraft and space vehicles and the direction of the technical phases of their manufacture and operation.

Civil Engineering (CIV): Studies that involve the planning, designing, construction, and maintenance of structures and public works, such as bridges or dams, roads, water supply, sewer, flood control and, traffic.

Computational Mechanics (COM): A study that applies the discipline and techniques of computer science and mathematics to solve large and complex problems in Engineering Mechanics.

Control Theory (CON): The study of dynamical systems, including controllers, systems, and sensors that are influenced by inputs.

Ground Vehicle Systems (VEH): The design of ground vehicles and the direction of the technical phases of their manufacture and operation.

Industrial Engineering-Processing (IND): Studies of efficient production of industrial goods as affected by elements such as plant and procedural design, the management of materials and energy, and the integration of workers within the overall system. The industrial engineer designs methods, not machinery.

Mechanical Engineering (MEC): Studies that involve the generation and application of heat and mechanical power and the design, production, and use of machines and tools.

Naval Systems (NAV): Studies of the design of ships and the direction of the technical phases of their manufacture and operation.

Other (OTH): Studies that cannot be assigned to one of the above subcategories. If the project involves multiple subcategories, the principal subcategory should be chosen instead of Other.
