For high-speed machines applications, eddy-current losses in the interior permanent magnet of synchronous machine (IPMSM) form a portion of the total losses which can be significant. Indeed, the magnets are exposed to the harmonic fields which rotate with respect to the rotor. The induced losses in the magnets provoke temperature arising that must be limited to avoid the risk of demagnetization. The...
In this paper an advanced simulation model of interior permanent magnet synchronous machine (IPMSM) is presented. The conventional dq-axis mathematical model is modified in order to include data derived from three-dimensional finite element analysis (FEA). Indirect interaction between FEA and circuit simulation enhances model fidelity embodying the influence of saturation and cross-coupling effects...
The increase of pole pairs numbers of the interior permanent magnet (IPM) synchronous machine with "flux concentration structures" can boost its air gap flux density, raise its efficiency and torque, and reduce its volume and weight. But there exists a suitable value. With the help of geometry module, this paper analyzes the relation between "flux concentration function" and the...
