About this document

Torque Density in PM Motors Analysis by Dantam Rao is a document available to read on EtoBox.

The document summarizes torque density metrics and achievements in permanent magnet motors developed under government programs. The highest continuous duty torque density demonstrated to date is 50 Nm/L, achieved by both radial-gap and axial-gap motors developed by L-3 Corporation and DRS using oil cooling. Torque density depends on factors like motor size, cooling approach, and efficiency, and tends to increase with larger motor size. Volume and torque metrics can be defined in various ways, so comparisons
