Teaching Methodologies
The teaching method includes theoretical classes with the use of slide presentations (PowerPoint or similar) to present the topics covered,
complemented by laboratory classes focused on solving illustrative exercises and performing experimental work in student groups.
Learning Results
It is intended that students acquire knowledge and skills encompassing theoretical, practical, and laboratory components in
electromechanical actuators.
By the end of the semester, students should be able to understand, design, size, analyze, optimize, protect, and implement
electromechanical actuation systems, focusing on three-phase induction motors, starters, and variable frequency drives.
These competencies are developed through lectures, laboratory practices, and applied problem-solving, fostering mastery of the following
topics:
• Operation of electrical machines and control equipment
• Design and implementation of industrial command and protection systems
• Design, execution, and operation of electrical installations
• Fundamental aspects of maintaining industrial electrical installations and electromechanical equipment
• Development of electromechanical maintenance plans
The approach prepares students for industrial challenges by aligning theory with practice.
Program
1. Design and Sizing of Power Drive Systems: Control and protection equipment; selection of components according to the application;
coordination of contactors and short-circuit protection devices; standardization, symbology, and preparation of control and power diagrams
for motor starting.
2. Optimization of Electromechanical Drives: Modeling the mechanics of drives; determination of mechanical parameters; operational
requirements and dynamic regimes.
3. Speed Variation and Position Control: Speed and position transducers; structure of soft starters and electronic speed drives; scalar
control (“V/f” and “E/f”) and vector control.
4. Complementary Aspects: Energy savings and future trends.
5. Special Power Drive Systems: Applications in electric traction and linear motors.
