4.4 Control of Permanent Magnet Synchronous Machine
4.4.1 Introduction
Permanent magnet synchronous motors (PMSM) have received increased attention in industry due to their mature material and design technology. Their high torque to inertia ratio, power density, and high efficiency make them an attractive alternative to industry's workhorse IM for many applications (Table 4.1).
