Abstract
In some examples, at least one connecting ring may connect a plurality of stator coils of the same phase. For instance, the at least one connecting ring may include at least one linear conductor formed in a ring-like shape. The linear conductor may include a plurality of terminal sections, each terminal section including an open groove extending perpendicular to a plane formed by the ring-like shape. The open grooves may be positioned around a circumference of the connecting ring for receiving respective wire ends of respective stator coils inserted into the open grooves for forming an electrical connection between the respective wire ends and the connecting ring at the respective terminal sections.
Claims20
A power distribution apparatus for a rotary electric machine, the power distribution apparatus comprising:
- at least one connecting ring that connects a plurality of stator coils of the same phase, the at least one connecting ring including at least one linear conductor formed in a ring-like shape, the at least one connecting ring including a plurality of terminal sections integrally formed in the linear conductor,
- each terminal section including an open groove extending in a direction parallel to an axis of rotation of the rotary electric machine, each open groove receiving a respective wire end of a respective stator coil inserted into the open groove for forming an electrical connection between the respective wire end and the connecting ring at a respective terminal section.
A rotary electric machine comprising:
- a stator including a plurality of stator coils arranged in a circular configuration;
- and
- a power distribution apparatus assembled to the plurality of stator coils, the power distribution apparatus having a ring shape and including a plurality of connecting rings,
- each connecting ring including a linear conductor formed into a ring-like shape and having a plurality of terminal sections for engaging with respective wire ends extending outward from respective stator coils of the plurality of stator coils, respective ones of the terminal sections engaging with respective ones of the wire ends by receiving the respective wire ends into respective open grooves formed in the respective terminal sections, each respective open groove being formed in a sidewall of a respective connecting ring at the respective terminal section and extending in a direction parallel to the wire ends.
An apparatus comprising:
- at least one connecting ring to connect a plurality of stator coils of the same phase, the at least one connecting ring including at least one linear conductor formed in a ring-like shape, the linear conductor including a plurality of terminal sections, each terminal section including an open groove extending perpendicular to a plane formed by the ring-like shape, the open grooves positioned around a circumference of the connecting ring for receiving respective wire ends of respective stator coils inserted into the open grooves for forming an electrical connection between the respective wire ends and the connecting ring at respective terminal sections.
