So be convenient for in constant head tank 210 motor magnet steel 30 paste fast accurate on motor housing 20's inner wall, and when the interval between two adjacent location strips 200 is less when leading to the arm to stretch into, because location strip 200 is close to motor housing 20's inner wall, consequently motor magnet steel 30 also is close to the casing inner wall, need not stretch into the arm this moment, only need stretch out the finger and go to press motor magnet steel 30 and can paste motor magnet steel 30 on motor housing 20's inner wall, and can not lead to motor magnet steel 30 to take place the skew when being close to motor housing 20's inner wall because of apart from the overlength.

In one embodiment, the motor housing 20 is threadably coupled to the base 100. In one embodiment, the base 100 is cylindrical, and the inner wall of the motor housing 20 is screwed with the peripheral side surface of the base 100. In one embodiment, as shown in fig. 5, the end face of the motor housing 20 is threaded with the mounting face 110, wherein the fixing surface 131 is provided with the first connecting hole 132, the end surface of the motor housing 20 is provided with the second connecting hole 22, the first connection hole 132 penetrates the annular mounting portion 130, first and second internal threads are respectively formed in the first and second connection holes 132 and 22, the magnetic steel mounting structure 10 comprises the connecting piece, the connecting piece is provided with an external thread, the connecting piece sequentially penetrates through the first connecting hole 132 and the second connecting hole 22, the first internal thread and the second internal thread are respectively matched with the external thread, this facilitates the detachment and attachment of the motor housing 20 to the annular mounting portion 130 of the base 100, and also ensures the stability of the attachment of the motor housing 20 to the base 100.
