The case of a pulsating-load testing machine shows how to ballpark qualities that are important for deploying electric motors. Crankshafts in running internal-combustion engines pulsate as well as ...

Translational and rotational motion are compared and contrasted. Rotational Inertia &Torque: Translational and rotational motion are compared and contrasted. Students learn to distinguish between ...

In this episode of Crash Course Physics, Shini sits down with us to discuss what torque is, how it works, why it works, and what it all has to do with this thing called "Moment of Inertia." Crash ...

Step motors are a natural choice when design specs call for low-cost automation with accurate, open-loop control. But finding the right stepper for a given application can be a challenge. There’s a ...

When I was talking about balancing a stick, I mentioned the moment of inertia. Moment of inertia is different than mass, but I like to call it the “rotational mass”. What does mass do? Things with ...

If you’ve ever played with tops, you know that some spin easily while others wobble. Ever wonder why? The answer has to do with rotational inertia, a property shared by all rotating systems. Sometimes ...

When it’s time to specify a high-performance motor that offers both precise positioning and cost efficiency, stepper motors offer many advantages over DC motors thanks to their brushless technology.

In a state of bewilderment one fine day, I asked a group of three mechanical engineers at this company where I was then employed if they could please explain to me the concept of “moment of inertia”.
