Spring 2010

 

 


MINTEC 226 Section 8004 / MELTEC 226 Section 2540 - Motors Controls and Controllers. (3 units)

Objective:       This one-semester course provides an introduction to magnetism, single-phase and three-phase power, motor control schematics, relays, with emphasis on troubleshooting motor control systems. Instruction will include lectures, videotape presentations, computer tutorials, and a possible field trip. Students will be assessed with exams, quizzes, laboratory activities, and degree of class participation. Credit from this course will apply to several INTEC Degrees/Certificates.

Instructor:      Jon Kropp.  The BEST way to contact me is via E-mail: kroppj@mjc.edu 

Telephone: 575-6598. Office: Sierra B242

Textbooks:      Electric Motor Controls 3rd Edition, by Rockis and Mazur, ATP Publishers

                        One 2-inch ring binder and 8 ½” by 11” notepaper

                        MINTEC/MELTEC 226 2009-2010 Lab Manual, may be purchased at the MJC Bookstore

 

Equipment:     You must wear protective eyewear (safety glasses), at all times, in the lab,

Please dress safely while in the lab. NO loose dangling clothing or jewelry, open toe shoes or sandals.

 

Class Hours:   Lecture – Mondays 11:40 – 1:45 PM, Laboratory – Wednesdays 11:40 – 2:45 PM.

This is a 16 Week class running from 1/11/10 to 4/21/10

Location:        Sierra Hall Rooms 114 and 102

 

Participation:  Credit will be given for class participation. Students who miss a class should contact another student to “catch-up” (Find a “study-buddy” and exchange phone numbers!). If you decide to drop the course you must fill out and submit a drop form in admissions. If you attend just one session of the course, you are responsible for dropping the course even if you never come to class again.

Homework:    Reading and lab assignments will be given weekly. Written homework assignments are collected at the beginning each class meeting. Rather than copying straight from the text, re-state homework answers in your own words.  Late work will not be accepted. Labs are due at the end of the laboratory period.

 

Exams:   Exams and Quizzes will be assigned during the semester.

The final exam will be administered in class on Wednesday, April 28th, 2010 at 10:30AM

Grading:                     Your course grade will be broken down approximately as follows:

Class Participation 18-22%                  Labs 28-32%

Homework 23-27%     Quizzes & Exams 23-27%

Grades are updated every few weeks at http://virtual.mjc.edu/kroppj (mouse click on the flag)

Etiquette:  Please help keep our spaces clean. The classroom and lab are NOT cleaned often. After completing your laboratory assignments, please be sure to leave the equipment and workstation in proper order.

Unprofessional Conduct:

Giving or receiving assistance during an exam, quiz, or activity will result in a grade of zero for that exam, quiz, or activity. Repeated offences will result in a “Fail” grade for the course.

Safety:    We work with lethal voltages therefore a safe laboratory environment is essential. Safety procedures are most often given during the lecture period. If, in the opinion of the instructor, you are not prepared to work in the lab, i.e. you appear to be under the influence of alcohol or drugs, or you are unaware of proper safety procedures, you will not be allowed to participate.

Study Hints:

               Prepare yourself before attending class by reading the assigned textbook / laboratory material. You will probably need to plan on several hours of reading per week. Read lab and lecture materials BEFORE class. If you don’t understand something from your reading then make a note of it and ask questions in class. Always bring your textbook to lectures.

Student Learning Outcomes:

1.      The student will be able to design, draw and test a functioning ladder diagram for a given type of motor control system using appropriate control language, labeling, numbering, and symbology.

2.      Using safe lab procedures the student will be able to analyze and interpret control language, identify control devices, and connect a properly functioning motor control circuit.
