Part I: DC Motors – Understanding Motor Technologies
This module dives into Direct Current (DC) motors, a fundamental building block for many automated systems, and explores various control techniques to regulate their operation.
Key Learning Objectives:
- DC Motor Fundamentals: Students will gain a thorough understanding of the working principles and different types of DC motors, including brushed DC motors and permanent magnet DC motors.
- Motor Control Techniques: The module explores various techniques for controlling DC motors, including:
- Permanent Magnet Motor Reversing: Students will learn how to control the direction of rotation of permanent magnet DC motors.
- DC Motor Control from AC Source using SCR: This section explores how to use a Silicon Controlled Rectifier (SCR) to control a DC motor powered by an Alternating Current (AC) source.
- Braking in DC Motors: Students will delve into methods for braking DC motors, a crucial aspect of safe and efficient operation in automated systems.
- Brushless DC Motors (BLDC Motors): The module introduces brushless DC motors, a variation of DC motors known for their efficiency and controllability. Students will explore the principles behind BLDC motors.
Overall Benefit:
By understanding DC motor fundamentals and control techniques, students gain the ability to select, control, and implement DC motors effectively in their automation projects. This knowledge will help students to design systems with precise motor operation and efficient control.
