Abstract

PURPOSE:To enhance strength against heat shock by making cutouts on the inner surface of the lid of a rotor case for housing an iron core with a plurality of magnets fixed thereto and also by making markings, on the outer surface of the lid facing the cutouts. CONSTITUTION:Four magnets 6 are glued to the outer periphery of an iron core 4 by matching each joint to each cutout 5 of the iron core 4. Then, it is housed inside a rotor case 1, and a lid 7 is fixed to the opening of the rotor case 1. Positioning grooves 9 incised on the outer surface of the lid 7 are signs of the magnets (6)'s joints 10, thus enabling the magnets 6 to be magnetized with the lid 7 on. A space is also made between the rotor case 1 and the magnets 6 or the iron core 4, and therefore there is less chance of any, break on the rotor case when heat shock is given.

However, in such resin-molded magnets, the magnet or iron core is in close contact with the resin, so the resin is prone to cracking when the temperature suddenly changes. Also, if you use magnets that are divided into multiple parts, the joints will be invisible (and magnetization will not be possible).Therefore, ring-shaped magnets are used, but ring-shaped magnets are expensive and have a strong magnetic force. There was a weak point.

According to this embodiment, the iron core (4) to which the magnet (6) is fixed is housed in the resin rotor case 11), and the opening (2) of the rotor case 'II) is sealed with the lid (7). As a result, a gap is created between the magnet (6), the iron core (4), and the rotor case (1), and even when heat shock is applied, the rotor case 11) is less likely to crack. Of course, since the notch (5) of the iron core (4) and the tab projection (8) of the lid (7) are engaged, the rotor case (1)
The iron core (4), the magnet (6)g, and the lid (7) are integrated, so that only the magnet (6) and the iron core (4) do not spin idle. In addition, the positioning groove (9) provided on the outer surface of the lid (7) serves as a mark for the seam (lα) of the magnet (6), so the magnet (6) can be attached while the lid (7) is covered.
It is possible to improve pump performance and reduce costs by using a split-type magnet (6) that is inexpensive and has a strong magnetic force. In addition, since there is no need to magnetize the magnet (6) in advance, there is no need to worry about iron powder adhering to the magnet (6) or the magnet (6) adhering to metal and breaking, and if it is demagnetized for some reason, it can be easily re-magnetized. can be done.
