Impact of Saturation on Transient Behavior of Interior Permanent Magnet Synchronous Motors
2006 Canadian Conference on Electrical and Computer Engineering, 2006Interior permanent magnet synchronous machines have larger ferromagnetic path along the quadrature axis and as a result, the q-axis magnetizing reactance saturates significantly under normal operating conditions. Although, the effective air-gap path length along the direct axis is large, the d-axis magnetizing reactance also saturates up to a certain ...

High-Efficiency Line-Start Interior Permanent-Magnet Synchronous Motors
IEEE Transactions on Industry Applications, 2004This paper presents a successful design of a high-efficiency small but novel interior permanent-magnet motor using NdBFe magnets. It is designed to operate both at line and variable frequencies. Line start with high inertia load was a special consideration.

Interior type permanent magnet synchronous motor analysis by equivalent circuits
IEEE Transactions on Energy Conversion, 1989Experimental tests show that steady-state core loss of interior-type permanent magnet machines changes with the terminal voltage in a peculiar way due to flux redistribution produced by armature reaction. An equivalent circuit is proposed to predict such loss through new parameters that can be easily determined by experimental tests.

Optimal Shape Design of Interior Permanent-Magnet Synchronous Motor
IEEE International Conference on Electric Machines and Drives, 2005., 2005Optimal shape design of interior permanent-magnet (IPM) synchronous motor has large effect in reducing the torque pulsation of the motor. However, the shape design variations should be feasible and manufacturable. In this research, optimal shape is obtained by drilling small circular holes in rotor.
