Abstract
The invention belongs to the technical field of a permanent-magnet brushless Halless dual-magnetic circuit motor, in particular relates to a winding armature of a permanent-magnet direct current motor. The winding armature comprises a winding and an iron core, wherein the winding is formed by sequentially connecting a plurality of copper sheets in a head-to-tail manner; the iron core comprises a plurality of iron core slices, and the iron core slices are arranged among the copper sheets at intervals; and each copper sheet comprises an upper expansion arm and a lower expansion arm, the upper expansion arm and the lower expansion arm are arranged in staggered way and connected via a vertical connection plate, and the shapes of the upper expansion arm and the lower expansion arm are symmetrically arranged by taking the connection plate as a center. The winding armature has the advantages that: 1, the contact area between the winding formed by the copper sheets disclosed by the technical scheme and the iron core slices is large, and thus, good heat conduction can be achieved; 2, forced water cooling of the winding is carried out due to the design of a cooling water jacket, and the heat dissipation capability of the winding is improved; 3, the temperature of the winding is controlled better, and the performance stability and reliability of the motor is maintained; and 4, groove filling rate can be improved to 98 percent, thus, the volume of the motor is greatly reduced, and power density is improved.
Description
Technical field
The invention belongs to a kind of brushless, permanently without Hall Double magnetic circuit motor technical field, refer to a kind of permanent magnet DC motor armature winding especially.
Background technology
Conventional direct current machine armature winding comprises winding 1 and iron core 2, and see accompanying drawing 1, its winding 1 all adopts the copper wire winding of circular section to form, and there is the larger gap 11 that can not fill up between circular copper wire all the time.So its copper factor is only about 75%, this is the main cause causing motor volume loose; The heat of armature winding spreads out of main by heat transfer, but contact area between circular copper wire is minimum brings difficulty to heat transfer, and the thermal convection in circular copper wire gap is also difficult to be formed, and this causes it the motor feels hot and the main cause of decrease in efficiency.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, and a kind of permanent magnet DC motor armature winding is provided.
The present invention includes following technical scheme, comprise winding and iron core, described winding is connected in sequence by several copper sheet head and the tail; Iron core comprises several lamination, and lamination and copper sheet interval are installed;
Described copper sheet comprises the upper exhibition arm of staggered floor setting and lower exhibition arm, upper exhibition arm is connected by vertical connecting plate with lower exhibition arm, shape line centered by connecting plate of upper exhibition arm and lower exhibition arm is symmetrical arranged, comprise first paragraph, to the second segment of center line bending, the 3rd section of inverse bending, the 3rd section of end arranges connecting ring; The connecting ring of the lower exhibition arm of n place copper sheet, the copper sheet that head and the tail are adjacent is fixed each other by the connecting ring of lower exhibition arm and the connecting ring of upper exhibition arm and is connected;
Angle between described upper exhibition arm and lower exhibition arm second segment is θ, and the copper sheet number of each winding is 360/ θ;
Total number of described winding, the number according to the copper sheet of filling in angle theta or lamination is determined.
The copper sheet of filling in described angle theta or the number of lamination are determined according to copper thickness and lamination thickness.
Beneficial effect of the present invention is, 1. the copper sheet winding of this technical scheme is very large with contact area unshakable in one's determination, so can well heat conduction.2. copper sheet winding forms very large plane with the stator two ends formed unshakable in one's determination, therefore stator can be fixed on after in motor cover, design cooling jacket and carry out forced water cooling to it, improve the heat-sinking capability of winding greatly outside motor cover.3. the temperature of winding is well controlled, and namely avoids high temperature also maintains motor stable performance and reliability to the damage of part.4. this structure can make the copper factor of winding bring up to 98%, thus the volume of motor is reduced greatly, and power density improves.
