Course Description

For any machines, prime movers and powertrains are necessary to realize the required functions. In automobiles, an engine is the prime mover and a transmission, a clutch, and a shaft are parts of the powertrain. In machine tools, a motor is used as the prime mover and the powertrain uses feed screws. In this lecture, the prime mover is taken up. Types, characteristics, principles, advantages and disadvantages of the prime mover are explained. In addition, examples of the powertrains are shown using mechanism models.


Evaluate comprehensively by participation in class, tests, reports, etc.

Course Goals

Understand the principles and basic characteristics of the prime movers and powertrains taken up in the lecture.
