Abstract
The invention discloses a permanent magnet motor magnetic steel assembly tool which comprises a magnetic steel guide device. A guide groove corresponding to a rotor sheet groove of a rotor core is formed in the magnetic steel guide device and used for guiding when magnetic steel is pushed. A magnetic pole recognition groove for placing magnetic poles is formed on the top of the magnetic steel guide device, and is arranged corresponding to the magnetic pole recognition groove. A magnetic pole distinguish magnet is arranged in the magnetic pole recognition groove. A principle that like poles repel and opposite poles attract between the magnet and magnetic steel is utilized to recognize the magnetic poles inside the magnetic guide pole recognition groove, the magnetic poles of the magnetic steel are recognized, so that defect that the magnetic poles of the magnetic steel are erroneously installed is avoided. After the magnetic steel is placed in the guide groove, the magnetic steel is pushed into the rotor sheet groove by pushing a small propelling block with slight force. According to the permanent magnet motor magnetic steel assembly tool, the occurrence that the magnetic poles of the magnetic steel are erroneously installed is avoided, magnetic pole yield is 100 %, breakage rate of the magnetic steel is greatly reduced, and assemble efficiency of the magnetic steel is improved.
