Specific embodiment
The half directly-drive permanent magnet electric machine structure of the utility model using low-speed half direct-driven magneto as shown in Figure 1, directly driven
Dynamic speed reducer operation, cancels original asynchronous machine, belt pulley and belt.Simultaneously according to its practical service condition, to motor knot
Structure optimizes, and half directly-drive permanent magnet main component of electrical machine includes: adjusting washer 4, connection end cap 5, motor stator 8, axle sleeve 13, axis
Cover baffle 12, rotor 10, bearing 14 and end plate 15.
Specific structure is as follows: motor stator 8 is installed on the inside of motor casing 7, motor stator 8 is equipped with machine winding 6, and motor is fixed
Sub 8 one end are fixed by seam allowance location and installation in connection end cap 5 and by screw, and connection end cap 5 is fixed on by screw to be subtracted
On fast casing body 2,8 other end of motor stator is fixed on end plate 15 by screw, and speed reducer input shaft 3 runs through reducer shell
2 and connection end cap 5 be installed on 7 inner connecting end lid 4 of motor casing and connect with 7 rear end of motor casing, 3 end of speed reducer input shaft passes through axis
13 connection rotor 10 of set, 10 end of rotor are equipped with magnet steel 9, and 13 front end of axle sleeve is equipped with groove 17, and axle sleeve baffle 12 is pacified
Loaded on being fixed on speed reducer input shaft 3 in groove 17 and by screw, installs and adjust between connection end cap 5 and bearing in reduction gears 18
Whole washer 4.Upper head plate 16 and bottom plate 15 are installed in 7 front of motor casing up and down, corresponding between upper head plate 16 and bottom plate 15 to slow down
Lid 11 is installed at machine input shaft 3, lid 11 is fixed by bolts on upper head plate 16 and bottom plate 15, upper head plate 16, bottom plate 15,
Single-groove grooved ball bearing 14 is installed between connection end cap 5 and rotor 10；The iron core axial length of rotor 8 is greater than motor
5 iron core axial length of stator.
Motor stator 8 is fixed by connection end cap 5 and reducer shell 2, rotor 10 is passed through axle sleeve 13 and subtracted
Fast machine input shaft 3 is fixed, and motor stator 8 is fixed when motor is powered, then rotor 10 drives speed reducer input shaft 3 to revolve
Turn, drives pumping unit operation.Wherein, adjusting washer 4 is for holding out against 18 outer ring of bearing in reduction gears；Axle sleeve 13 is according to different model
Speed reducer input shaft structure, size are adjusted, and are processed convenient for rotor 10 is unified；Axle sleeve baffle 12 be used for fastening shaft sleeve
13 with rotor 10.10 iron core axial length of rotor is effectively avoided slightly larger than 8 iron core axial length of motor stator
