Zhu, Z.Q., Chen, Y.S. and Howe, D. (2002) Iron loss in permanent-magnet brushless AC machines under maximum torque per ampere and flux weakening control. IEEE Transactions on Magnetics, 38 (5 (Par). pp. 3285-3287. ISSN 0018-9464
Abstract
The airgap flux density distribution, flux density loci in the stator core, and the associated iron loss in two topologies of brushless AC motor, having a surface-mounted magnet rotor and an interior-mounted magnet rotor, respectively, are investigated when operated under maximum torque per ampere control in the constant torque mode and maximum power control in the flux-weakening mode. It is shown that whilst the interior magnet topology is known to be eminently suitable for flux-weakening operation, due to its high demagnetization withstand capability, its iron loss can be significantly higher than for a surface-mounted magnet machine.
