* Detailed instructions for the laboratory sessions are included in the lab-handouts, which can
be downloaded from the ECE 362 course website:
http://www.ece.uwaterloo.ca/~ece362/Labs.htm
Instructions for the project on simulation of electric machines (Lab 4) will be posted on the ECE
362 website at a later date. Choose the lab partners, date and time, then you can sign-up
electronically Go to the website (https://ecewo.uwaterloo.ca/cgi-bin/WebObjects/UWonline ). Use
email ID in login field and student ID in password to login. If you are unable to signup yourself for
any reason, contact the lab instructor in person.
D: ASSIGNMENT PROBLEMS
Bi-weekly assigned problems will be posted. The selected assignment questions could be from the
textbook or from external sources. Assigned problems are not handed in; however, very similar
problems will be selected for the midterm. Solution will be discussed in the tutorial and will be
posted later on. Teaching Assistants (TAs) will help students during the "tutorial hours". Additional
assistance will be provided during “Office Hours” and upon e-request.

A- LABORATORY INSTRUCTIONS
IMPORTANT SAFETY NOTE: All the students must strictly follow all the safety instructions
given below. In case of any question or concern, please contact the LAB INSTRUCTOR. If you fail
to follow the safety instructions, or do not attend the lab prologue, you may forfeit the privilege of
attending the laboratory session.
1. Each student must “Independently” submit answers to the pre-lab questions on or before the
dates specified in the lab schedule. Students who fail to submit prelabs or obtain ‘unsatisfactory’
evaluation on their pre-labs will not be permitted to do the labs. Students are asked to discuss such
situations with course instructor.
2. Students must be punctual and the lab doors will be closed before laboratory safety and
equipment handling related presentation begins.
3. All the students in the group should be involved in the experiment. Failure to do so could result in
the student being asked to leave the laboratory and lab instructor and/or professor will counsel with
the student after the lab session.
4. No food or drink is allowed in the lab. Bottled water in the common area is the only exception.
5. One laboratory report per group is to be submitted in the drop-off box located at CPH 1333.
Unless otherwise stated, the report will be due on the date indicated.
6. Please contact the Lab Instructor for any concerns or any lab conflict with the class.
7. A minimum of 50% in lab part is mandatory in order to receive a pass grade for the course.
8. There will be a reduction of 25% if:
• the student fails to attend the lab on the scheduled date and time, unless prearranged with the lab
instructor.
• the lab report is submitted late.
B- LAB SCHEDULE
Lab 1, 2 and 3 are hardware (hands-on) experiments and lab 4 is a modeling and simulation
exercise. Students are working in groups. A group will have three students. If there are two
students in a group, your lab instructor may add third student without your permission to
accommodate all the students in the schedule.
Lab signup:
Note: Students without signing up are not allowed to conduct experiment.
Choose the lab partners, date and time, then you can sign-up electronically Go to the website
(https://ecewo.uwaterloo.ca/cgi-bin/WebObjects/UWonline ). Use email ID in login field and
student ID in password to login.
If you are unable to signup yourself for any reason, contact the lab instructor in person.
Lab manuals:
Lab handouts can be downloaded from UW-ACE to be announced by Prof. in the class.
(https://uwangel.uwaterloo.ca/uwangel/frames.aspx).
Lab Time:
8:30 am to 11:30 am. Laboratory Room – CPH-1333.
