Design and Analysis of Interior Permanent Magnet Motor With Magnetic Isolation and Heat Dissipation Integrated Auxiliary Slot

IEEE Access, 2023
This paper presents a novel auxiliary slot interior permanent-magnet (IPM) motor. It not only plays the role of magnetic isolation and reduces the eddy-current (EC) loss, but also facilitates the ventilation and heat dissipation of the rotor.

Berry's Phase in the Presence of a Dissipative Medium [PDF]

, 2001
We consider the spin 1/2 model coupled to a slowly varying magnetic field in the presence of a weak damping represented by a Lindblad-form operators. We show that Berry's geometrical phase remains unaltered by the two dissipation mechanism considered ...
