Influence of Permanent Magnet Thickness on Loss of Permanent Magnet Brushless DC Motor
The permanent magnet thickness is a main consideration for the permanent magnet brushless DC motor design. The effect of the magnet thickness on the different loss of the motor and motor output power is considered through the circuit-field coupling finite element method under the full-load operation. 2D transient thermal analysis is carried out as the verification of the design result. The motor is fabricated and the experimental results prove that the design motor with the certain magnet thickness can fulfill the requirements.
