I want to know the answer to the following question:
What does continuous torque density refer to?
All the background I'm provided with is that "The continuous torque density of conventional electric machines is determined by the size of the air-gap area and the back-iron depth, which are determined by the power rating of the armature winding set, the speed of the machine, and the achievable air-gap flux density before core saturation.". Is that enough to answer the question?
