Fundamentals of Mechatronic Actuators

When an electronic system must manipulate a mechanical component, an actuator is necessary. Because of constraints on cost and complexity, the vast majority of these actuators are some form of rotary drive connected to an armature. Understanding the various types of actuators which are available, as well as the differences between them is key to making informed design decisions. Each lab in this manual begins with an overview of the basics of interfacing and commanding the most common mechatronic actuators. Students then investigate the essential decisions and comparisons made in mechatronics to gain insight and intuition into the design process.

This lab focuses on the two principal types of DC motors: brushed and brushless. Through hands-on activities, students will analyze the differences between these motors in form, function, and application, as well as the implications of these differences.
This lab covers the principal commercial solutions to the need for simple position controlled actuation. The first section of the lab introduces the stepper motor, including mechanical design and control requirements. Various different control signal patterns are considered, including full-step, half-step, and wave stepping. The second section covers the mechanical design and operation of the commercial servomotor. The PWM command signal for position control is contrasted to the open-loop PWM control of the DC motor. In the final section, the stepper and servo motors are compared and contrasted with regards to design requirements such as holding torque, position accuracy, and control precision.
