Electric motors are everywhere, yet many people working around them only understand the basics: apply power, the shaft turns, and hopefully the overload does not trip five minutes later.
Behind that spinning shaft sits a surprisingly large subject involving magnetic fields, torque, speed, losses, starting current, voltage regulation and machine design.
The Udemy course Mastering Electrical Machines: Theory, Design, Applications takes a deep dive into DC machines, synchronous machines and induction machines. I believe it is a very good course for electrical engineering students and professionals who want a detailed understanding of how motors and generators actually behave.

What Does the Course Cover?
Created by Amr Saleh, the course currently contains 33 sections, 308 lectures and approximately 49 hours and 33 minutes of video. Udemy lists a 4.6 rating from 95 reviews, more than 700 enrolled students and a most recent update in February 2026.
The curriculum is divided into three substantial areas:
- DC machines
- Synchronous machines
- Induction machines
This is not a quick overview. Nearly 50 hours of material makes it closer to a full university-style electrical machines program than a casual weekend course.
DC Motors and Generators
The DC-machine section begins with construction and operating principles. Students learn about armature windings, field windings, commutators, brushes, generated voltage and equivalent circuits.
The course then covers different DC generator and motor types, their performance characteristics, starting methods, speed control, torque regulation and testing procedures. MATLAB projects are included to help students model machine performance rather than relying only on hand calculations.
That combination of theory and simulation is useful. A motor equation may look rather lifeless on paper, but changing a parameter in MATLAB and watching the speed or torque curve move makes the relationship easier to understand.
Synchronous Machines
The synchronous-machine section goes well beyond a basic alternator explanation.
Topics include generator construction, alternator windings, voltage regulation, excitation systems, governor control, synchronisation, parallel operation and generator capability diagrams. The course also examines salient-pole machines, synchronous motors, synchronous condensers and practical machine-design problems.
This section should be particularly relevant to learners interested in power generation, large industrial motors or electrical power systems.
Induction Motors and Starting Methods
Three-phase induction motors receive their own major section.
Students learn about motor construction, equivalent models, torque-speed characteristics and common starting methods, including:
- Direct-on-line starting
- Star-delta starting
- Autotransformer starting
- Soft starters
- Rotor-resistance starting
The course also discusses speed-control methods, variable-frequency drives, single-phase induction motors, induction generators and machine testing.
These topics connect well with real industrial applications. Understanding why a motor draws high starting current—or why torque changes with slip—can make troubleshooting much less dependent on guesswork.
Course Materials and Projects
According to the listing, students receive approximately 900 lecture slides, reference materials, quizzes, assignments and MATLAB Simulink files. Practical MATLAB projects are used throughout the DC, synchronous and induction-machine sections.
The assignments are valuable because electrical machines cannot be learned properly by passive watching alone. At some point, you need to calculate the numbers yourself. Painful perhaps, but necessary.
Who Is This Course For?
The course should suit:
- Electrical engineering students
- Power and automation engineers
- Industrial maintenance engineers
- Electricians expanding their theoretical knowledge
- Power-plant operators
- Researchers and engineering educators
Udemy recommends knowledge of electrical engineering fundamentals. Complete beginners with no understanding of electrical circuits or magnetism may find the course difficult.
Are There Any Downsides?
The main drawback is simply the size of the course. Almost 50 hours is a serious commitment, especially when calculations and assignments are included.
It is also more theoretical than a hands-on motor-repair course. Learners wanting practical bearing replacement, rewinding, alignment or vibration-analysis training will need additional specialised instruction.
Final Verdict
Mastering Electrical Machines: Theory, Design, Applications is a very good comprehensive course for anyone who wants to study motors and generators in real depth.
Its strongest feature is the combination of theory, design calculations, performance analysis and MATLAB projects across three major machine families. It is demanding, but for a serious learner, there is a substantial amount of useful material here.
