Magnetic pole suitable for large and medium-sized low-speed permanent magnet motors

The invention discloses a magnetic pole suitable for large and medium-sized low-speed permanent magnet motors and belongs to the technical field of permanent magnet motors. The magnetic pole comprisesa plurality of small magnetic pole segments, at least one axial magnetic-conducting pull rod, at least two end pressing plates and a plurality of tightening nuts, wherein the plurality of magnetizedsmall magnetic pole segments run through the magnetic-conducting pull rods and are connected into a whole in series and two ends are pressed and fixed through the end pressing plates and the tightening nuts to form a complete magnetic pole. According to the improved magnetic pole suitable for the large and medium-sized low-speed permanent magnet motors disclosed by the invention, respective technical advantages of existing surface-mounted magnetic pole structure and embedded magnetic pole structure are integrated, the advantages that the embedded magnetic pole structure is simple in process and high in reliability are
