Summary

Students will acquaint with the fundamentals of dynamics and kinematics of the drive. They will acquaint with energy - thermal balance of energy transfer. They will acquaint with the characteristics of different types of motors (electric motors, combustion engines, hydro-motors, pneumatic motors) and gears (mechanical, hydrostatic, hydrodynamic, combined). They will be able to choose the suitable combination of motor and gear at the drive design.
