ECE 32300 - Electromechanical Motion Devices and Systems Laboratory

Lab Hours: 3 Credits: 1

Professional Attributes
Upper Level Lab

Normally Offered: Each Fall, Spring

Requisites:
ECE 32100 [may be taken concurrently] and (ECE 20008 or ECE 20800)

Catalog Description:
Experiments closely coordinated with EE 321 involving measurement of fundamental parameters of various electromechanical devices using modern instrumentation techniques. Computer simulation is used to predict steady-state and dynamic operating characteristics. Comparison of predicted and measured performance is emphasized.

Course Objectives:
To reinforce experimentally the basic principles of electromechanical motion devices and to familiarize students with the operating characteristics of various electromechanical devices used in control applications including de, induction, brushless dc, and stepper motors.
