Did you know there is a difference between torque and torque density?
In pursuit of improved design and performance of mechanical systems, designers, manufacturers and end users must consider numerous parameters and scenarios. One often overlooked parameter is torque density. While not as commonly considered as other measurements, torque density can help designers make smarter decisions by focusing on “where the work gets done.”
Torque is defined as the measure of the turning force on an object being rotated, such as a bolt or an automotive flywheel.
Torque density expresses the ratio of torque capability to volume, in units of Joules per cubic metre or foot-pounds per cubic foot.
In short, torque density measures the torque-carrying capability of a component in a given weight and space envelope.
