Abstract
The utility model belongs to the technical field of motors, in particular to an armature coil for a middle-sized DC motor, wherein the armature coil is integrally formed by an entire-turn coil, inside the entire-turn coil there are provided four windings, the four windings are vertically and uniformly distributed, and two free ends of the entire-turn coil are connected to form a single outgoing wire terminal. The armature coil for a middle-sized DC motor aims at resolving the problems that the prior armature coil for a middle-sized DC motor is unreasonable in structure design, thereby being large in machining difficulty, labor intensity of workers, copper wire consumption and weight, and low in motor reliability, etc.
Description
Technical field
The utility model belongs to technical field of motors, is specifically related to a kind of medium-sized armature of direct current motor coil.
Background technology
The most structural design of existing medium-sized armature of direct current motor coil is comparatively complicated, and as shown in Figure 1, it connects into drum organization by upper half-turn coil 1 and lower half-turn coil 2, and junction is provided with two terminals 3; Upper half-turn coil 1 and lower half-turn coil 2 are equipped with 4 windings, and form upper and lower double-layer structure, and every layer is provided with 2 windings.Such structural design, armature coil has 16 the end of a thread, has not only strengthened the difficulty of processing, has increased workman's the amount of labour, has reduced operating efficiency; And increased to a great extent the consumption of copper cash, and increased the weight of armature coil, reduced the reliability of motor.In addition, in the different groove operating process of motor, such structural design, usually at two terminal 3 different grooves in place, this make operate very inconvenient.
The utility model content
The purpose of this utility model: unreasonable and bring that difficulty of processing is large, workman's the amount of labour is large and the problems such as the consumption of inefficiency, copper cash is large, armature coil weight is large, reliability motor is low in order to solve existing medium-sized armature of direct current motor loop construction design, and a kind of medium-sized armature of direct current motor coil is proposed.
The technical solution of the utility model: a kind of medium-sized armature of direct current motor coil, one-body molded by whole circle coil, be provided with four windings in described whole circle coil, described four windings are levels and are uniformly distributed, and two free ends of described whole circle coil connect and compose single terminal.A kind of medium-sized armature of direct current motor coil of the present utility model, because it is one-body molded by whole circle coil, be provided with four windings in whole circle coil, four windings are levels and are uniformly distributed, two free ends of whole circle coil connect and compose single terminal, therefore not only single terminal quantity is few, only has eight the end of a thread in whole armature coil, and there is no contact in the middle of whole circle coil, on the one hand, not only greatly reduce the difficulty of processing, reduced workman's the amount of labour, improved operating efficiency; On the other hand, save to a great extent the utilization rate of copper cash, alleviated the weight of armature coil, improved to a great extent the reliability of motor.
Further, described whole circle coil is provided with two effective edges, the upper strata winding of one of them effective edge and lower floor's winding from.
Upper strata winding and lower floor's winding from, like this, when the operation of different groove, upper strata winding and lower floor's winding can be embedded into respectively in different grooves, thereby greatly simplify the operation of different groove, improved operating efficiency.
The accompanying drawing explanation
Fig. 1 is the structural representation of medium-sized armature of direct current motor coil in prior art;
Fig. 2 is the structural representation of the embodiment of a kind of medium-sized armature of direct current motor coil of the present utility model.
Embodiment
As depicted in figs. 1 and 2, the utility model provides a kind of medium-sized armature of direct current motor coil, one-body molded by whole circle coil 4, be provided with four windings in whole circle coil 4, four windings are levels and are uniformly distributed, two free ends of whole circle coil 4 connect and compose single terminal 8, and whole circle coil 4 is provided with two effective edges 5, the upper strata winding 6 of one of them effective edge 5 and lower floor's winding 7 from.In the present embodiment, armature coil forms drum organization by whole circle coil 4, with existing armature coil, compares, and whole circle coil 4 middle parts do not have contact, like this, can guarantee the unfailing performance of motor; Moreover, only have single terminal 8, therefore only have eight the end of a thread in whole armature coil, amount to 16 the end of a thread with two terminals 3 in existing armature coil and compare, such structural design, the utilization rate that can save copper cash, alleviate the weight of armature coil, reduce production costs.In addition, the design of single terminal 8, simplified the difficulty of processing greatly, reduced workman's the amount of labour, improved operating efficiency.
In addition, by upper strata winding 6 and lower floor's winding 7 from, like this, can be so that the operation of different groove be very reliable.
Above-described is only preferred implementation of the present utility model, should be understood that for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement, these can not affect effect and practical applicability that the utility model is implemented.
Claims (2)
