Abstract
A method for manufacturing a permanent-magnet motor rotor includes manufacturing a rotary shaft, a permanent magnet, a front end cover, a rear end cover, and a magnetic yoke unit, where the magnetic yoke unit contains multiple pole shoe parts and one iron core part, where each pole shoe part and the iron core part are connected therebetween via a connecting strip; manufacturing a rotor spacer; all positioning holes of the magnetic yoke unit correspond to the permanent-magnet through hole of the rotor spacer to form a permanent-magnet passage; inserting the permanent magnet into the permanent-magnet passage; inserting tightening bolts; cutting off the mid-section of each connecting strip, overlapping the pole shoe parts to form a rotor pole shoe, overlapping the iron core parts to form a rotor iron core; and arranging respectively the front end cover and the rear end cover on a front end and a rear end.
