Abstract
A coil support for preformed flat coils of a stator of an electric rotary motor includes an annular supporting structure and a plurality of columns extending upwardly from the supporting structure. The columns are spaced apart from each other to form a corresponding plurality of coil receiving portions configured to hold the preformed flat coils in place before a potting operation. Each of the coil receiving portions is configured to support a lower part of one of the preformed flat coils.
Claims15
A coil support for preformed flat coils of a stator of an electric rotary motor, the coil support comprising:
- an annular supporting structure;
- and
- a plurality of columns extending upwardly from the supporting structure and being spaced apart from each other to form a corresponding plurality of coil receiving portions configured to hold the preformed flat coils in place before a potting operation,
- wherein each of the coil receiving portions is configured to support a lower part of one of the preformed flat coils, and
- wherein the plurality of columns comprise a first and a second group of columns, a minimum width of the columns of the first group being greater than a minimum width of the columns of the second group, and wherein one or more adjacent columns of the second group are arranged in-between two columns of the first group.
A coil support for preformed flat coils of a stator of an electric rotary motor, the coil support comprising:
- an annular supporting structure;
- and
- a plurality of columns extending upwardly from the supporting structure and being spaced apart from each other to form a corresponding plurality of coil receiving portions configured to hold the preformed flat coils in place before a potting operation,
- wherein each of the coil receiving portions is configured to support a lower part of one of the preformed flat coils, and
- wherein an upper portion of each of the columns comprises a groove of a predefined shape comprising a first groove portion extending between two of the coils in a mounted state of the coils in which the coils are mounted on the coil support, and a second groove portion extending radially and outwardly from the first groove portion.
A coil support for preformed flat coils of a stator of an electric rotary motor, the coil support comprising:
- an annular supporting structure;
- and
- a plurality of columns extending upwardly from the supporting structure and being spaced apart from each other to form a corresponding plurality of coil receiving portions configured to hold the preformed flat coils in place before a potting operation,
- wherein each of the coil receiving portions is configured to support a lower part of one of the preformed flat coils, and
- wherein the coil support further comprises a first and second plurality of insulating sheet supports extending radially and outwardly from the annular supporting structure, wherein the first plurality of insulating sheet supports extend further in the radial direction than the second plurality of insulating sheet supports, and wherein each of the insulating sheet supports of the first plurality of insulating sheet supports is located between two insulating sheet supports of the second plurality of insulating sheet supports such that a circulate insulating sheet has a corrugated shape in a mounted state on the first and second plurality of insulating sheet supports.
