Abstract
A system for manufacturing a stator assembly having a stator core that includes slots and coils inserted into the slots includes a core loader, an insulation sheet inserter at a rear of the core loader to insert an insulation sheet into the slots, a coil former at a rear of the insulation sheet inserter to form the coils by bending, a preliminary aligner along the coil former to align the coils into a dummy core, a coil inserter at a rear of the insulation sheet inserter and connected to the preliminary aligner to insert the coils into the slots of the stator core, a coil winder at a rear of the coil inserter to twist end portions of the coils inserted into the stator core, and a varnish impregnator at a rear of the coil winder to impregnate varnish into the slots.
Claims19
A system for manufacturing a stator assembly having a stator core that includes a plurality of slots along a circumference and a plurality of coils inserted into the slots, the system comprising:
- a core loading unit configured to load the stator core;
- an insulation sheet inserting unit disposed at a rear of the core loading unit and configured to insert an insulation sheet into the slots;
- a coil forming unit disposed at a rear of the insulation sheet inserting unit and configured to form the coils by bending;
- a preliminarily aligning unit disposed along the coil forming unit and configured to preliminarily align the coils formed by bending into a dummy core;
- a coil inserting unit disposed at a rear of the insulation sheet inserting unit, connected to the preliminarily aligning unit, and configured to insert the coils aligned in the dummy core into the slots of the stator core;
- a coil winding unit disposed at a rear of the coil inserting unit and configured to twist end portions of the coils inserted into the stator core to stably hold the coils;
- and
- a varnish impregnation unit disposed at a rear of the coil winding unit and configured to impregnate varnish into the slots.
A system for manufacturing a stator assembly having a stator core including a plurality of slots along a circumference and a plurality of coils inserted into the slots, the system comprising:
- a core loading unit configured to load the stator core;
- an insulation sheet inserting unit disposed at a rear of the core loading unit and configured to insert an insulation sheet into the slots;
- a coil forming unit disposed at a rear of the insulation sheet inserting unit and comprising a plurality of coil forming devices disposed by a predetermined spacing, wherein the coil forming unit is configured to form the coils of a segment type by bending a supplied coil material in multiple stages;
- a preliminarily aligning unit disposed along the coil forming unit and configured to preliminarily align the coils formed by bending into a dummy core;
- a coil inserting unit disposed at a rear of the insulation sheet inserting unit, connected to the preliminarily aligning unit, and configured to insert the coils aligned in the dummy core into the slots of the stator core;
- a coil winding unit disposed at a rear of the coil inserting unit and configured to twist end portions of the coils inserted into the stator core to stably hold the coils;
- and
- a varnish impregnation unit disposed at a rear of the coil winding unit and configured to impregnate varnish into the slots.
A method for manufacturing a stator assembly having a stator core including a plurality of slots along a circumference and a plurality of coils inserted into the slots, the method comprising:
- loading the stator core on a core loading unit;
- inserting an insulation sheet into the slots by an insulation sheet inserting unit;
- forming the coils by bending by a coil forming unit;
- supplying a dummy core by a conveyor transfer apparatus and preliminarily aligning the coils in the dummy core;
- inserting the preliminarily aligned coils in the dummy core into the stator core by a coil inserting unit;
- twisting the coils inserted into the stator core by a coil winding unit to stably hold the coils in the stator core;
- and
- impregnating varnish into the slots by a varnish impregnation unit to fix the coils.
