As an example, the concave-convex flange may be provided with a screw hole, and a screw is used to pass through the screw hole to fix the concave-convex flange to the output end of the rotating shaft. For example, when the motor is applied to a powder manufacturing apparatus (i.e., a target apparatus), by coating a sealant in the screw hole, external dust impurities and liquid can be prevented from entering the casing through the gap between the screw and the screw hole during movement, thereby affecting the normal operation of the motor. Alternatively, the male and female flanges and the rotating shaft may be connected by spline connection and fixed by jackscrew, without departing from the scope of the present invention. After the concave-convex flange is fixed at the output end of the rotating shaft, the inner surface of the concave-convex flange is close to the outer surface of the first end cover, so that a small gap can be reserved between the inner surface of the concave-convex flange and the outer surface of the first end cover, the rotating shaft is guaranteed to be capable of driving the concave-convex flange to rotate, and the friction resistance of the outer surface of the first end cover cannot be received.

In this embodiment, the storage cavities include a first storage cavity and a second storage cavity. Specifically, a first groove is axially arranged on the outer surface of the first end cover, and the first groove and the inner surface of the concave-convex flange form a first storage cavity; at least one second groove is radially arranged on the outer surface of the first end cover, and a second storage cavity is formed by the second groove and the inner surface of the concave-convex flange. More specifically, the second groove is an inverted triangular groove, and those skilled in the art can select other shapes according to actual needs. In a specific embodiment, when the motor is applied to a powder manufacturing apparatus, external dust impurities and liquid may be stored in the first and second storage cavities after passing through a gap between the inner surface of the concavo-convex flange and the outer surface of the first end cap in motion, thereby preventing dust from entering the inside of the cabinet. The rear end of the motor is also provided with a second end cap for closing the rear end of the housing. Preferably, the first end cover is provided with a first bearing chamber, and a first bearing of the motor is positioned in the first bearing chamber; the second end cover is provided with a second bearing chamber, a second bearing of the motor is positioned in the second bearing chamber, and the rotating shaft is positioned through the first bearing and the second bearing and provides rotating support. Preferably, a wave spring is axially arranged between the inner surface of the first bearing chamber and the first bearing, and the wave spring is used for providing axial pre-tightening force for the first end cover and the concave-convex flange, so that a certain axial displacement space is formed after the concave-convex flange and the rotating shaft are fixed. The surface of casing is provided with a plurality of slots for increase the heat radiating area of motor, improve the natural cooling's of motor effect. As an example, the grooves are uniformly distributed on the outer surface of the casing and surround the outer surface of the casing in a rectangular or curved shape, so that the cooling time of the motor is further reduced, and the heat dissipation efficiency of the motor is increased.

step one, transverse fixation, a position finder body (22) is placed at the top of a placing plate (1), then a pull ring is utilized to pull a rotating sleeve (18) outwards, then the rotating sleeve (18) is held and rotated, at the moment, the rotating sleeve (18) can drive a limiting plate (15) to rotate under the action of a reinforcing column (16), so that a bidirectional stud (14) is driven to rotate, at the moment, a sliding plate (12) can move under the action of a limiting column (11), so that a connecting column (13) is driven to move, and further a fixed shell (2) is driven to move, and the transverse position of the position finder body (22) is limited by the fixed shells (2) on the two sides;

step two, longitudinally fixing, namely rotating the one-way stud (4), and enabling the one-way stud (4) to move downwards under the action of the reinforcing plate (3) positioned above, so as to drive the moving plate (5) to move downwards along the positioning column (6), further drive the supporting column (7) to move in the same direction, further drive the adjusting plate (8) and the pressing plate (9) to move downwards, enable the pressing plate (9) to be attached to the top of the finder body (22), and enable the second spring (20) to have upward supporting force for the finder body (22), so that the pressing plate (9) and the finder body (22) are attached more tightly;

and step three, mounting the placing plate (1), and mounting the connecting plate (24) at the preset position of the direct drive motor by using the second mounting plate (25) and the mounting hole, so that the placing plate (1) is mounted inside the direct drive motor, and the mounting of the position finder body (22) is completed.
