Research on Remanence Problem of a BLDCM Electromagnetic Lock-apparatus
The experimental method was used to detect the relationship between the failure of a BLDCM electromagnetic lock-apparatus and the structural parameters.By adjusting the unlocking voltage and the height of lock-apparatus housing boss,the non-locked factor caused by residual magnetism was excluded,the BLDCM quality stability was improved,it laid the foundation for the wide application of this brushless BLDCM.
