Brushless direct current motor for driving centrifugal pump, has printed circuit board with slot-like recess in range between contacts, where recess intersects straight line between contacts, and recess extending on both sides of line

摘要

The motor has a stator, a rotor and a printed circuit board (2) that is arranged with a set of board contacts and a printed circuit board carrier. The printed circuit board comprises a slot-like recess (6) in a range between two tinned contacts (4a, 4b) of different potentials. The recess intersects a straight line between the contacts, where the recess extends on both sides of the straight line. Spacing is arranged between the two contacts. A separation bar is arranged in the recess, where the separation bar is arranged as one-piece.
