An array type magnetic circuit system includes a T yoke, magnetic steels and a washer. The T yoke includes a bottom plate, and more than two central columns located on the bottom plate and distributed in an array. The magnetic steels are respectively disposed at two sides of each of the central columns and provide a magnetic energy for the magnetic circuit system. Hole positions coupled with the central columns correspondingly are formed on the washer and the washer is tightly connected to the T yoke. According to the array type magnetic circuit system, under a condition in which a plurality of magnetic circuits are combined, the T yoke and the washer are respectively taken as a component, so that the precision of a product can be controlled better.
