Description
Technical field
The utility model belongs to the motor manufacturing technology field, relates to automatic winder with the improvement of motor, is a kind of groove drum specifically.
Background technology
The groove drum of automatic winder rotates by groove drum and drives, and at present, groove drum is three-phase variable frequency motor, and power is 200W, and efficient is 73%, accounts for the over half of whole bobbin-winding machine power consumption, consumes energy too large.Cause the too large reason of groove drum power consumption to be: 1. the excessive 0.5mm of stator and rotor clearance; 2. the stator winding resistance value is larger; 3. materials'use die casting fine aluminium, sliver and end ring have pore and impurity.
How to improve groove drum, change the too large deficiency of its power consumption, this is the technical problem that the art needs to be resolved hurrily.
Summary of the invention
The problems referred to above that the utility model exists for solving prior art provide a kind of groove drum, improve electric efficiency, reduce power consumption.
The purpose of this utility model is achieved through the following technical solutions:
A kind of groove drum, comprise casing, stator, rotor, stator comprises stator core, winding upper end and winding bottom, fore bearing shelves and rear bearing shelves are set in the rotating shaft of rotor, the bearing chamber corresponding with fore bearing shelves and rear bearing shelves is set on the casing, and it is characterized in that: described stator and rotor clearance are 0.45mm; Described bearing chamber and stator concentricity are 0.05; Described bearing guard and rotor outer circle concentricity are 0.03.
To improvement of the technical scheme: the winding upper end height of described stator is 24-26mm, the winding bottom height 22-24mm of described stator.
To further improvement in the technical proposal: described diameter of stator bore is 55mm, and described rotor diameter is 54.55mm.
To further improvement in the technical proposal: the described stator number of phases is 3, and every phase winding is 4, and every group of number of turn is 69, every circle girth: great circle is 373mm, and ringlet is 317mm; The winding resistance of described stator is 5.3 Ω/phase.
To further improvement in the technical proposal: described rotor material is cast copper.
Advantage of the present utility model and good effect are:
Bearing guard of the present utility model is consistent with the bearing chamber Sizes, reduces the impact on the bearing clearance; Bearing chamber is concentric with stator; Bearing guard is concentric with rotor outer circle, reduces mechanical loss.Stator and rotor clearance are down to 0.45mm by 0.5mm, have effectively reduced the heating loss of groove drum.Stator winding end height reduce shortens the coil overall length, thereby reduces groove drum stator winding resistance value, reduces copper loss.Change rotor material into cast copper by the die casting fine aluminium, improve the quality of rotor.
