Abstract
Motor coil pillar, pillar is made up of Body of pillar, paulownia horse epoxy glass mica paper tape, alkali-free glass fibre band; Angle α after the bending of Body of pillar one end is set to acute angle; Body of pillar outer ring is provided with paulownia horse epoxy glass mica paper tape, and the outer ring of paulownia horse epoxy glass mica paper tape is provided with alkali-free glass fibre band; Between pillar and stator coil, be provided with soft end hoop, tie is around pillar, soft end hoop and stator coil colligation.The utility model has prevented that the loosening sagging and coil insulation of motor coil from damaging, and has improved motor stabilizing, has extended motor useful life.
Description
Technical field
The utility model belongs to motor device field, particularly a kind of motor coil pillar.
Background technology
Motor makes in use, and because motor coil end is long, motor is constantly vibrations in running, there will be motor coil loosening, motor coil outer end is sagging, and coil insulation is damaged, the phenomenon that motor winding is scrapped, this vibrations not only can be shortened the useful life of motor, when serious, by damaging the insulating barrier of coil, cause coil turn-to-turn short circuit or shorted to earth, directly motor damage, produce serious consequence, bring very large economic loss to user.
Summary of the invention
The purpose of this utility model will solve the problems of the technologies described above.
The purpose of this utility model is achieved in that motor coil pillar, comprises stator coil, pillar, it is characterized in that: described pillar is made up of Body of pillar, paulownia horse epoxy glass mica paper tape, alkali-free glass fibre band; Angle α after the bending of Body of pillar one end is set to acute angle; Body of pillar outer ring is provided with paulownia horse epoxy glass mica paper tape, and the outer ring of paulownia horse epoxy glass mica paper tape is provided with alkali-free glass fibre band; Between pillar and stator coil, be provided with soft end hoop, tie is around pillar, soft end hoop and stator coil colligation.
The utility model has prevented that the loosening sagging and coil insulation of motor coil from damaging, and has improved motor stabilizing, has extended motor useful life.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to restriction of the present utility model:
Motor coil pillar, comprises stator coil 1, pillar 2, and described pillar 2 is made up of Body of pillar 201, paulownia horse epoxy glass mica paper tape 202, alkali-free glass fibre band 203; Angle α after Body of pillar 201 one end bendings is set to acute angle; Body of pillar 201 outer rings are provided with paulownia horse epoxy glass mica paper tape 202, and the outer ring of paulownia horse epoxy glass mica paper tape 202 is provided with alkali-free glass fibre band 203; Between pillar 2 and stator coil 1, be provided with soft end hoop 3, tie 4 is around pillar 2, soft end hoop 3 and stator coil 1 colligation.
When concrete enforcement, the paulownia horse epoxy glass mica paper tape 202 that Body of pillar 201 outer rings arrange, has good flexibility under normal conditions, holds coil and processes after moulding, there is higher electric property, mechanical strength, be suitable for the large and medium-sized HV Electric Machine Coil insulation by 155 DEG C of working temperatures; It is level and smooth that the alkali-free glass fibre band 203 that paulownia horse epoxy glass mica paper tape 202 outer rings arrange has outward appearance, and without damaged, good insulation preformance, pulling force extra-heavy, be applicable to doing fire insulation flame-retardant layer; One end after Body of pillar 201 bendings is provided with waist-shaped hole, with bolt, Body of pillar 201 and stator pressing ring is fixed, and tie 4 is bound around pillar 2, soft end hoop 3 and stator coil 1.
