Module goal - Knowledge and skill to be achieved by students |
|
The goal of this course is to provide students with a basis for understanding functioning of special types of electrical machines and their control. Working principles, basic structural form, control mechanisms, characteristics and application will be considered for all types of electrical machines will be considered thoroughly. <br> |

DC motors (without collector) with permanent magnets (PM motors): Three phase half, bridge and pendular DC PM motors. Static torque-position characteristics. Torque pulsation. Electronic positional switching. Control principles. <br> Step motors: Variable-reluctant, PM and hybrid step motors. Unipolar and bipolar electronic converters. Static torque-position characteristics. Dynamic characteristics and stability. <br> Switch-reluctant motor: magnetic structure, electronic converters, role of positional feedback electronic commutation; torque generation, motor and generator modes; power-voltage and phase control; working performance. <br> |

Didactic methods |
|
Course lessons are taught by the professor in lecture halls. These lectures include teaching and solving practical examples and mathematical problems presented by the professor (10 hours). In addition to this form of lecturing, there are two more: <br> 1. Tutorials, (10 hours) in which students ( under tutor's guidance and supervision ), solve mathematical problems using MATLAB-Simulink software. <br> 2. Laboratory practices (15 hours) which include practical analysis of how electrical machines function. <br> |

Exams |
|
During the course students earn points according to the following system: <br> - Attending classes and tutorials: 10 points, student with more than three absences from lectures and/or tutorials cannot get these points. <br> - Home assignments, laboratory reports and/or seminary thesis: maximum of 10 points, <br> - Partial exams: two partial exams; each positively evaluated partial exam (more than 10 points) to maximum 20 points. <br> During the time of each partial exam (90 minutes) students will solve simple questions with goal of testing whether student has basic theoretical knowledge, multiple choice problems, as well as one open-answer problem. Students who gained less than 20 points during the semester must repeat that course. <br> Students who earned 40 or more points during the semester will take a final exam; the exam consists of discussion of problems from partial exams, home assignments and answers to simple questions related to course topics. <br> Final oral exam provides maximum of 40 points. In order to get positive final grade, students must earn minimum of 20 points in this exam. Student failing to earn the minimum must take the makeup oral exam. <br> Student, who earned 20 or more, and less than 40 points during the semester, will have to take the makeup exam. The makeup exam is organized in the following manner: <br> - Written part structured similarly to partial written exam, during which students solve problems in topics they failed on partial exams (less than 10 points); <br> - Oral part structured the same as the oral part of the final exam. <br> |
