Stator coil of direct current motor and stator coil insulation integration method

Abstract

The invention provides a stator coil of a direct current motor and a stator coil insulation integration method, and relates to the technical field of the direct current motor. The stator coil of the direct current motor comprises multiple numbers of turns of buses, insulating paper bands and a silicone rubber insulating band, wherein the multiple numbers of turns of buses are configured into the coil appearance of the stator coil of the direct current motor; the insulating paper bands are placed between adjacent two turns of buses in a cushion manner; and the outer sides of multiple numbers ofturns of buses are bundled with the silicone rubber insulating band. The stator coil insulation integration method is used for manufacturing the stator coil of the direct current motor; and by virtueof the stator coil of the direct current motor, the motor input current can be highly increased without changing the motor appearance, so that the motor can output higher power and torsion, and the service life of the motor is not shortened.

Description

technical field

[0001] The invention relates to the technical field of DC motors, in particular to a stator coil of a DC motor and an insulation integration method for the stator coils. Background technique

[0002] The main heat source of a DC motor is the winding in the stator, that is, the coil. The cross-sectional area of ​​these coils is called the wire gauge.

[0003] With the development of society, railway locomotives and oil field drilling rigs have more and more demands on the power and torque of the matching motors. In order to allow the motors to output greater power and torque, designers often have to enlarge the wire gauge of the stator coil and increase the Motor stator current method.

[0004] However, due to the fact that the space between the locomotive and the drilling rig is generally fixed, the shape of the supporting motor cannot be enlarged, and the space for enlarging the stator coil wire gauge inside the motor is also very limited. When the stator ...

Embodiment

[0049] Please refer to figure 1 and figure 2 , the present embodiment provides a stator coil 100 of a DC motor, including:

[0050] The bus bar 10 has a plurality of turns, and the multi-turn bus bar 10 is configured as a coil shape of a stator coil 100 of a DC motor;

[0051] Insulating paper tape 20, insulating paper tape 20 is placed between two adjacent turns of bus bars 10;

[0052] Silicone rubber insulating tape 30 , the outside of the multi-turn bus bar 10 is wrapped with silicon rubber insulating tape 30 .

[0053] in, figure 1The stator coil 100 of the DC motor in is actually wrapped completely, and the vacancy on the left is to show the busbar 10 therein. It should not be understood that the actual finished product is also this style. figure 1 and figure 2 The film heat shrinkable tape in the figure just means the coating during processing, and the actual finished product does not have this layer structure.
