These small magnets are insulated from each other and can cut down electromagnetic eddy current. When the permanent magnet motor is running, the motor will generate harmonic and the magnet will generate skin effect, these all will bring a lot of eddy current loss. And then, the temperature of permanent magnet rises, which results in irreversible demagnetization and affects the safety and stability of motor operation. So the design of laminated magnet can just cut down this risk.

Major Characteristics High Br, high Hc, relatively high BHmax Higher in cost than neodymium iron boron Highly resistant to oxidation Most grades function well at temps up to 300°C (572°F) Energy product ranges from 18 MGOe to about 33 MGOe Relative cost index (by weight): 60 In most cases, the eddy current loss of permanent magnets is much lower than iron loss and copper loss of the motor, but it will generate a large temperature rise in the high-speed motor and the high power density motor. Ideally, stator magnetic field and rotor magnetic field of PMSM are rotating synchronously, or relatively static, thus permanent magnets without eddy current loss in such case. In fact, there are a series of space and time harmonics are existing in the air gap magnetic field, and these harmonic components are stemming from cogging effect, non-sinusoidal distribution of magnetomotive force and phase current. The harmonic magnetic field will link with rotor magnetic field and hence generated eddy current and caused relevant eddy current loss. It should be also noted that the harmonic magnetic field and eddy current loss will rise with increasing motor speed.
