Problems solved by technology

It can be seen from the arrangement that the span of each equalizing line on the entire circumference is 180°, so there are 280 / 2=140 equalizing lines arranged on any radial section of the entire equalizing line disc, so that It is difficult to assemble the embedded wire of the wire reel, and if the size is too large, it will further affect the axial ventilation and cooling of the motor, thereby affecting the operation of the motor and the improvement of the design capacity

Embodiment Construction

[0011] The present invention provides a kind of connection method of double-wave winding type B voltage equalizing line, and its method is:

[0012] First, the two grooves every 180° on the circumference are divided into a group corresponding to the same equipotential point, such as figure 1 As shown, the grooves numbered 1 and 281 are one group, corresponding to the same equipotential point; the grooves numbered 3 and 283 are one group, corresponding to another equipotential point; and so on.

[0013] Secondly, each group of two equipotential points is connected by only one equalizing line. That is, the two equipotential points corresponding to the two slots numbered 1 and 281 need only be connected by one equalizing line, that is, the one equalizing line is only connected to 1-281, but does not need to be connected to 281-1.

[0014] In this way, compared with the prior art, the present invention only uses one equalizing line to connect the three equipotential points of eac...

Abstract

The invention discloses a wire connecting method for duplex wave winding B voltage equalizing wires. Two slots at an interval of 180 degrees on a circumference form a group of the same equal potential point. The method is characterized in that: two equal potential points of each group are connected through only one voltage equalizing wire. Compared with the prior art, the two equal potential points of each group are connected by adopting only one voltage equalizing wire, namely one voltage equalizing wire is saved, but the voltage equalizing effect is achieved likewise. Therefore, the using amount of 1 / 2 voltage equalizing wires can be saved, copper materials are greatly saved, and the inserted wire assembly of a wire coil is certainly easier.

Description

technical field [0001] The invention belongs to the field of motor manufacturing, in particular to the technical field of manufacturing large-scale low-speed direct-current motors, in particular to a method for connecting Class B equalizing lines of double-wave windings of large-scale low-speed direct-current motors. Background technique [0002] In large-scale low-speed DC motors, the armature winding often adopts a double-wave winding with a B-type equalizing line. The equalizing line is mainly used to eliminate the unbalanced magnetic circuit caused by manufacturing deviation and uneven spatial distribution in motor manufacturing. and circuit unbalance effects. The best way for the voltage equalizing line is to use full voltage equalizing, that is, each turn of the winding is connected to the equalizing line, but due to the influence of the armature space layout and the difficulty of embedding wires, in actual manufacturing, each slot is often used (multiple turns of win...
