Learning objectives

The course provides the basic knowledge required for the usage of the most common electrical machine and electric drives.

Prerequisites

The students are expected to be familiar with the notions of mathematics, physics, electrical and electronic circuits taught in the 1st level degree in Mechanical Engineering.

Course unit content

a) An Introduction to Electric machines
b) Transformers
c) Rotating machines
d) Electric Drives

Full programme

a) An Introduction to Electric machines
Electric machines classification. The main components of the electric
machines.
Joule losses and iron losses: the efficiency of the electrical machines.

b) Transformers
Ideal transformer and real transformer.
No load operations and rated load operations.
Voltage drop, power, losses and efficiency of electrical transformer. Three phases transformers.

c) Rotating machines
Induction machines: mechanical and electrical behaviour. Induction motor start-up and velocity regulation.
Direct Current machines: electrical and mechanical behaviour, start-up and velocity regulation.
Permanet Magnet Synchronous Machines (PMSM): a.c. and d.c. PMSM, electrical and mechanical behaviour.
Permanet magnet step motor, reluctance step motor and hybrid step motor.
Electric Drives classification.

d) Electric Drives
The main components of electric drives: speed and position transducers, current transducers. Analog and digital PID regulators, PLC.
Electric drives based on permanent dc motors: torque control and velocity control.
DC motor supply: soft switching chopper.
Electric drives based on PMSM: torque control and velocity control. Electric drives based on induction motors: torque and speed control. Incremental electrical drives: basic stepping motor control circuits.

Lecture notes

Teaching methods

Classroom lectures and exercises solved by the instructor and by students. Some lectures use slides available to students for downloading.

Assessment methods and criteria

Oral exam. There is a single exam for the two modules making up the integrated course. Students will have to demonstrate knowledge of the components and circuits treated in the lectures, and understanding of their behavior and operation. It is considered important that students be able to solve simple quantitative exercises by hand calculation.
