Description

  The present invention relates to an armature, a winding method for an armature, and a DC motor.

  In an armature of a direct current motor, there is one in which each tooth arranged in parallel in the circumferential direction with respect to the armature core is bifurcated to have a pair of branch portions (Patent Document 1). The winding wound around this armature is a pair of branch portions in which the central side of the armature core is concentratedly wound around the base end portion of each tooth and the outer side of the armature core is formed in a bifurcated shape. The winding is applied between the branch portions of adjacent teeth using distributed winding. As a result, a DC motor with less cogging is realized.

JP 2010-98927 A

  By the way, in the armature having the above-described configuration, the commutator is provided with a short-circuit line in which the plurality of segments are electrically connected in order to make the plurality of segments have the same potential. The winding ends of the windings are connected to the risers of the segments connecting the short-circuit wires.

  Generally, when connecting the start or end of the short-circuit wire to the winding end of the winding on the riser of the segment, the winding end of the winding is hooked on the riser of the segment after the start and end of the short-circuit wire is hooked on the segment riser. The part is hung on the riser of the segment, and the winding work is performed.

  Therefore, the winding end portion of the winding may be hooked on the riser of the same segment where the starting end portion or the terminal end portion of the short-circuit wire is hooked. In this case, when the winding end portion of the winding is latched to the riser of the segment, the latching portion of the starting end portion or the terminal end portion of the short-circuit wire that is latched earlier is loosened by the latching, When the starting end or terminal end of the short circuit wire and the winding end of the winding are connected together by fusing or the like, the short circuit wire may not be connected with high accuracy.

In particular, it becomes a problem in a DC motor having a large number of windings, a number of segments, and a large number of magnetic poles.
In addition, as the number of windings and the number of segments connecting the windings increase, the distance between the risers of adjacent segments decreases, and the winding ends of the windings are fastened to the segment risers. The riser of the segment adjacent to gets in the way. For this reason, it has been impossible to perform an easy and highly accurate winding operation in a short time.

  The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide an armature that can be connected without loosening a short-circuit wire and that can easily perform winding work with high accuracy. The object is to provide a wire winding method and a DC motor.

An armature for solving the above-mentioned problem is a short-circuit wire that has a plurality of segments as a set, a plurality of the sets, and the plurality of segments having the same potential for each set are electrically connected to each other. The non-terminal portion between the start end and the end of each pair of short-circuit wires is the same set as the segment to which the start end and the end are connected and is hooked on a riser of a different segment The non-terminal portions of each set are hooked to the risers of the segments so as not to be adjacent to the other non-terminal portions in the circumferential direction. The windings are wound using the risers of the respective segments, and the risers of the segments to which the start ends of the respective short-circuit wires are connected and the end portions of the respective short-circuit wires are connected. Segment riser winding winding Unused.

  According to the said structure, the winding end part of the coil | winding is not latched together in the riser by which the start part and termination | terminus part of a short circuit line are latched. Therefore, the latching portions of the short-circuit wire start end and termination portion are not affected when the winding end of the winding is latched. There is no.

  An armature winding method for solving the above-described problem is that an armature is wound between a plurality of segments, each of which has a plurality of sets, and each set has the same potential. A riser of a different segment including a short-circuit line to be in a conductive state, and a non-terminal portion between the start end portion and the end portion of each pair of short-circuit wires being the same set as the segment to which the start end portion and the end end portion are connected A winding method of an armature having a commutator hooked on a non-terminal portion hooked on a riser of a different segment of the same set with respect to each short-circuit wire and a non-terminal portion of another set. Short-circuit wire connection step of connecting the start and end portions of the short-circuit wire to the same set of segments so as not to be adjacent in the direction, and for each set of segments, the segment of the segment excluding the riser of the segment that hooked the non-terminal portion The riser A riser bending step of bending in a direction in which the start and end portions of the entanglement are held, and a winding winding step of winding the winding using the risers of the segments that are not bent by hooking the non-end portions of each set With.

  According to the above configuration, the riser of the segment formed by hooking the non-terminal portion of each short-circuit wire is wound with the winding end portion and the winding is wound, and the start end portion and the termination portion of the short-circuit wire are hooked. The riser of the winding is not hooked together on the riser. Therefore, the latching portions of the start end and the termination end of the short-circuit line are not affected when the winding end of the winding is latched. As a result, there is no possibility that the latching portions of the start end and the end of the short-circuit line are loosened.

  Further, in the short-circuit connection process, the risers of the segments hooked with the non-end portions, that is, the risers of the segments used for winding of the windings are arranged so as not to be adjacent in the circumferential direction. All risers were folded except for the riser used for winding.

  Accordingly, when the winding end of the winding is hooked on the riser, the riser that is not used for winding the winding is bent, so that there is no obstructing riser, and winding of the winding can be performed easily and accurately.

  In the above-described armature winding method, the winding winding is performed after either the riser bending step or the fusing step of joining the riser and the start and end portions of the short-circuit wire by fusing. It is preferable to move to a round process.

According to the said structure, the start end part and termination | terminus part of a short circuit line are electrically connected with respect to a riser.
In the above-described armature winding method, after the winding winding step, the riser of the segment hooked with the non-terminal portion used for winding of the winding, the non-terminal portion of the short-circuit wire, and the winding It is preferable to join the winding end part by fusing.

According to the above configuration, the non-terminal portion of the short-circuit wire and the winding end portion of the winding are electrically connected to the riser.
A DC motor for solving the above problems has an armature manufactured by the winding method of each armature.

  According to the above configuration, the armature of the DC motor does not have a risk of loosening the latching portions of the start end and the end of the short-circuit wire, and the winding of the winding can be performed easily and accurately.

  According to the present invention, the short-circuit wire can be connected without loosening, and the winding work can be easily and accurately performed.
