Abstract :
Cogging torque exist by the interaction of a permanent magnet and a ferromagnetic core. The cogging torque is caused by non-uniform air gap reluctance. In some cases the cogging torque is an unwanted phenomenon and need to be reduced as possible. A way to reduce the cogging torque is by using Halbach array. A Halbach array is designed to make uniform airgap reluctance and this will reduce the cogging torque which is produced by the permanentmagnet machine design. The Halbach array also decrease the magnetic flux in one side close to zero and increase the magnetic flux at the other side, it will also reduce iron losses. But in the interior permanent-magnet machine such as MOLINA UI?s motor, the magnets position is inside the iron core while Halbach array is commonly used in exterior type. In this experiment there is no change in motor design, only the magnet ratio parameter is varied and combined with 3- segment Halbach array. This experiment is purposed to study the effect of the magnet ratio to motor cogging torque and iron losses. The experiment model is developed by a finite-element base program with Maxwell stress tensor method.
