The Importance of Torque Density


Torque density is an often overlooked parameter when it comes to designing mechanical systems, but understanding it can help build more efficient machines. Engineers and manufacturers consider a number of factors in order to maximise the system’s performance, but calculating the torque density for each and every component in the mechanical system is not yet a commonplace process.

It should be though, as a mechanical system designed with torque density in mind will perform better and for longer than a machine designed without any consideration given to torque density. You will still require torque limiter suppliers like Yorkshire-based YB Components, but the overall performance of the mechanical system will be much improved.

So what exactly is the difference between torque and torque density? Let’s dive right in and find out.

Torque vs. Torque Density

Torque is the measure of a twisting or turning force, specifically on an object being turned or rotated. In contrast, torque density represents the ratio of torque capability to volume, measuring it in units of energy density called joules per cubic metre. This means that torque density measures how much torque-carrying capability a particular component has in a specific weight and space.

Torque density is actually similar to power density, which is the term sometimes used to measure the amount of power that can be generated in a particular space. Torque density works pretty much in the same way, though instead of measuring power, it measures the ratio of torque capability to volume.

How Torque Density Benefits Machine Design

Torque density can be used to gauge the potential performance of various machine design concepts, especially when it is applied during the concept evaluation stage of mechanical engineering.

Usually at the concept phase, there will be a selection of potential design solutions available. Each solution’s torque densities can help determine whether or not it is the best solution for a particular scenario, such as operating in a confined space.

Torque density can provide a wide variety of end user benefits, including producing a more efficient machine operation by reducing the amount of space required and extending the service life of machinery and equipment because of the more suitable components used in the machine’s manufacture. The optimal component selection also helps to reduce noise during operation.
