Abstract
The utility model relates to an improved electromotor, in particular to a permanent magnetic low speed synchronous motor, comprising a main body; wherein, the main body is provided with a casing; wherein, a ladder inner round assembling half coupling is arranged at the outer end of the casing, and the half coupling is provided with an end cover; the casing is mounted on the device through the end cover, and the end cover is firmly fixed between the casing and the device for bearing relatively large axial force. The utility model has the advantages of novel and unique structure, and being reliable and convenient in assembling, satisfying the special requirements of small clearance and high coaxial degree; and in addition, the end cover can be generally interchanged and processed in mass, thus obviously improving the performance and expanding the application field of the electromotor, and having boarder development prospect.
Description
Technical field: the utility model relates to a kind of improvement of motor, specifically a kind of permanent magnet low speed synchronous motor.
Background technology: according to the knowledge of the applicant, present three-phase permanent low-speed synchronous motor the time has air gap big in assembling, and axiality is low, the assembly structure complexity, and defective such as unreliable, it is undesirable to cause assembling effect, and motor performance is poor.
Summary of the invention: technical problem to be solved in the utility model overcomes the deficiency of above-mentioned technology exactly, provide a kind of assembly structure simple, novel unique, air gap is little, axiality height, reliable and practical permanent magnet low speed synchronous motor.
The technical scheme that its technical problem that solves the utility model adopts is a kind of permanent magnet low speed synchronous motor, and it includes main body, establishes casing on the main body, it is characterized in that the casing outer end is provided with the interior circle assembling seam of step, is equipped with end cap on the seam.
The utility model novel structure uniqueness, convenient and reliable assembly, it is little to have satisfied the permanent magnet low-speed motor air gap, the characteristic requirement that axiality is high, end cap has been realized general exchange and batch machining, and motor properties is significantly improved.
Description of drawings: the utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Embodiment: as can be seen from Figure 1, a kind of permanent magnet low speed synchronous motor of the utility model, it includes motor main body 5 and end cap 4 two parts.Wherein, motor main body 5 is a prior art, and this does not describe in detail.Establish casing 1 on the main body 5.Casing 1 outer end is provided with the interior circle assembling seam of step, is equipped with end cap 4 on the seam.End cap 4 is in the form of annular discs, and it is provided with flange 6.Cover flange 6 bottom surfaces and casing outer face at grade, lip diameter is less than circle seam diameter in the casing.Also be provided with the fastening V-type groove in location on end cap 4 cylindricals.Casing 1 and end cap 4 are fixed by steel ball.Recessed end holding screw 2 on the casing 1 pushes up steel ball 3 in the end cap V-type groove, steel ball half in end cap V-type groove, second half makes the correct location of end cap fastening in the pit of recessed end holding screw 2.Utilize steel ball and combining of end cap V-type groove can make the holding screw direction needn't pass through the axle center, can on the casing seam circumference of end cap V-type bottom land correspondence, arbitrarily arrange in the 360 degree scopes and freely assemble.After casing and equipment were installed by cover flange, end cap is fastened between casing and the equipment can bear bigger axial force.
The utility model novel structure uniqueness, convenient and reliable assembly, it is little to have satisfied the permanent magnet low-speed motor air gap, the characteristic requirement that axiality is high, end cap has been realized general exchange and batch machining, and motor properties is significantly improved.Enlarge the application of this motor, had more vast potential for future development.
