Abstract

The utility model relates to a stator of no-trough electrical machinery composed of a base, a circular ring sleeve barrel-shaped iron core positioned in the base, uniformly distributed windings, 3-4 lead wires, an insulation layer between the iron core and the windings, an encapsulation layer, etc. Due to the adoption of smooth no-trough iron core, the wiring rate of the windings is increased above 65%, and therefore, the output torque is improved and the manufacturing process of the motor is simplified.

Description

Stator of no-trough electrical machinery

The utility model belongs to the parts of motor, relates to a kind of stator of slotless electric machines.

Slotless electric machines is the lower motor of a kind of moment of inertia, it is little to have time constant, starting torque is big, servo-actuated is good, advantages such as overload capacity is strong, these advantages make slotless electric machines come into one's own and be applied in some fields, but, existing slotless electric machines, because magnet is arranged on the motor stator, iron core and winding are arranged on the rotor, the external lead-out wire of winding directly and winding link, make slotless electric machines compare with the groove motor is arranged, exist manufacturing process complicated, cost is higher, production cycle is longer, volume is bigger, be the more high defective of cost performance, it is restricted in further applying; Chinese patent ZL892149310 provides a kind of half slotless electric machines, still has aforementioned deficiency.

The purpose of the utility model is intended to overcome above-mentioned the deficiencies in the prior art, provides a kind of iron core and winding etc. to be arranged at the stator of the slotless electric machines on the motor stator.

Content of the present utility model is: a kind of stator of slotless electric machines, comprise support (6), it is characterized in that also comprising the annular sleeve-like iron core (1) that laminates by one group of core stamping that is socketed in the support (6), be positioned at the enamelled wire winding (2) of support (6) and iron core (1) internal circular surfaces, be positioned at the insulating barrier (4) between iron core (1) and the winding (2), the inner surface that reaches winding (2) between support (6) and the winding (2) has adhesive embedding layer (3), and winding (2) has 3～4 lead-out wires.

One end of the interior winding of support described in the utility model content (6) (2) can also be provided with patchboard (5), and 3～4 external lead-out wires (7) link and (promptly 3～4 lead-out wires insulate each other) insulated from each other by patchboard (5) and described winding (2) lead-out wire.

The both ends of the surface of winding described in the utility model content (2) have adhesive embedding layer (3).

When adopting the utility model stator, permanent magnet can be adopted on the rotor, also iron core and winding construction can be adopted.

The utlity model has following characteristics:

(1) owing to iron core, winding are arranged on the motor stator, and employing is level and smooth, the annular sleeve-like iron core of slotless, the manufacture craft of the level and smooth stator armature of slotless electric machines is simplified greatly, space winding wiring rate is improved, can reach more than 65%, equal volume motor output torque is greatly improved, and improves work efficiency, reduce production costs greatly;

(2) at winding one end patchboard is set, as the tie-plate of external lead-out wire and winding lead-out wire, manufacture craft is simplified, lead-out wire is not easy-to-draw, roll over, pull apart, and reliability improves, and result of use is better.

Fig. 1 is the utility model embodiment sectional structure schematic diagram;

Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.

Among the figure: 1-iron core, 2-winding, 3-adhesive embedding layer, 4-insulating barrier, 5-patchboard, 6-support, 7-lead-out wire.

The utility model is described in further detail by embodiment below in conjunction with accompanying drawing:

A kind of stator of slotless electric machines is made of support 6, iron core 1, insulating barrier 4, winding 2, adhesive embedding layer 3, patchboard 5 and lead-out wire 7; Iron core 1 is laminated smoothly by core stamping, the annular sleeve-like of slotless also is socketed in the support 6, trade mark enamelled wires such as winding 2 employing QAN-1/y are uniformly distributed in the internal circular surfaces of support 6 and iron core 1, insulating barrier 4 is isolated both between winding 2 and iron core 1, after making the winding moulding with suitable frock clamp, adopt epoxy resin or other existing jointing material with winding 2 embeddings, and between support 6 and winding 2, the inner surface of winding 2 and both ends of the surface form adhesive embedding layer 3, the patchboard of making by printed circuit board material 5 be positioned at winding 2 lead-out wires, one end face and with winding 2 fixed bondings, 3 or 4 winding 2 lead-out wires (being applicable to two-phase or three phase electric machine respectively) and corresponding external lead-out wire 7 link modes such as (be welded on respectively) connecting on the patchboard 5 by patchboard 5 and are insulated from each other.

The utility model is not limited to this embodiment, and the utility model content all can be implemented.
