| Abstract: | The brushless direct current motor (BDCM) used in attitude control and energy storage flywheel features a structure of large equivalent air-gap and large ratio of diameter to length. To this kind of machine, the air-gap magnetic flux density distribution along the circumference and axes length is studied respectively. As a result, the equivalent magnetic flux leakage coefficient and the equivalent air-gap magnetic flux density calculating coefficient, which are important for the motor design, are put forward and calculated. The validities of the study and calculation are verified by the prototype machine experiment. |
