As we continue our journey to design a Linear Synchronous Motors, we realize that a lot of current is needed for this to function. Controlling the electromagnets with a sine wave AND using digital...

There is some math involved in determining the drive frequency for your LSM, but I have simplified it for you in this video. The end formulas are simple. We'll guide you through the math and one...

https://youtu.be/w52p8JoS2cI Wouldn't it be cool to have a backyard roller coaster with and LSM launch. Well, that is what this video series wants to accomplish. First we will explain what LSM is...

Impossible! It broke again in the same spot. Why? Well, let's find out. Also, how are we going to prevent it from happening again? New materials? Different wheels? Lower Loadings? [aweber...

I often see young engineers who understand the information presented so far, but have great difficulty implementing the process. I was once the epitome of this engineer. The first time I was asked to...

In addition to combining shear and normal stresses with Mohr’s circle, we also need to know how to add stresses from multiple sources. Some stresses add linearly but others add by the square root...
