碩士 === 國立虎尾科技大學 === 動力機械工程研究所 === 93 === This paper aims to develop a coaxial motor with a novel structure. The internal and external brushless DC motors used to drive planetary gear trains individually. The novel design is composed of two parts which provided smooth rotational speed, low velocity, high torque, large-scales reduce ratio, controlled direction, and change speed. This paper devoted the main of three drive types for a coaxial motor to analyze the motion, dynamics, and design structure. Meanwhile proceeded to study and manufacture the structure model. In this paper, the concept of relative velocity was applied to the analysis of motion of planetary gear trains. To determinate output rotational speed and control velocity model. And the moment equilibrium was used to derive mathematic model of torque of a coaxial motor. In order to analyze of dynamics by the way of torque pass on the mechanism. Furthermore, computer aided tri-dimensional interface application was applied to reduce inertia of parts. The structure is able to achieve an objective of light mass. In the future, proposed to provide an important component of a motor-driven cart.
