This electric motor control circuit training software is quite detailed. Starting off with wiring diagrams vs. Ladder diagrams and motor control theory, coving the entire AC motor control system. Solenoids, timers, sensors, relays, troubleshooting, even an introduction to PLCs is included.

- Electric Motor Design Hi there! My name is Antti Lehikoinen (D.Sc.), and I help small businesses with problems including electric motors. Software Development.
- EMWorks develops electromagnetic software to virtually prototype and validate electric motors, transformers, high voltage and eddy current devices, batteries, solenoids, antennas, RF and Microwave components, and more. Its products have built-in thermal, motion, and structural solvers.
- Electrical machines design. Electrical machine design software, synchronous motor modeling software, electrical motor FEM simulation, electrical machine electromagnetic torque, induction motor schema calculation analysis. QuickField packages that can be applied to the various aspects of electrical machines design: DC magnetics.
As a motor operates from no load to full load, its torque varies with speed. The relationship between speed and torque is often shown in a graph, called a speed-torque curve. This curve shows the motor’s torque, as a percentage of full-load torque, over the motor’s full speed range, shown as a percentage of its synchronous speed. NEMA classification is based on the speed-torque curves. Typical speed-torque curve for designs A, B, C, and D is shown below:

Made it this far? Great, and nice to meet you! My name is Antti Lehikoinen, D.Sc. (PhD in tech, basically), currently a postdoctoral researcher in Aalto University, Finland.
More importantly, I also collaborate with awesome people like yourself whenever an interesting opportunity arises. Do you have a problem regarding electrical machines or magnetic components? I might be able to help. And unlike maybe some of my competitors, I won’t just show you the correct answer on a pdf – I’ll teach you exactly how to reach it yourself. Knowledge transfer, in case you prefer the business-y term.
Are you, for example, really short on skilled personnel for design or R&D? Sounds like my cup of coffee, so let’s have a talk.
Having trouble with winding losses? Worry not – they’re my specialty, and can be analysed really fast with the correct tools.
Modelling/simulation trouble in general, with machines or magnetics? You might benefit greatly from my very own fully functional FEA suite that I know inside out – easily tailored to your needs. It’s open-source, so you can freely use it no matter what.
Not really a motor person yourself, but involved in a start-up dealing with electric machines of some kind nevertheless? Let’s get you started on the right track right away – you’ll learn a lot while we’re at it!
In any case, let’s get in touch!
Still not convinced? Please check out my personal website. If we’re going to work together, you should anyway get some kind of prior impression of me, to decide if we could make a good team in your opinion. While you’re here, let’s also connect on LinkedIn.
