Welcome to the official website of Changzhou Hemm Intelligent Technology Co., LTD
16 mm size coreless Brushless DC Motors from our coreless brushless motor factory can avoid the pulsation of air gap magnetic induction caused by uneven magnetic resistance in the teeth.
It can eliminate the pulse loss in the armature core and the surface loss on the main pole surface.
