Abstract
The present disclosure is generally directed toward a method of assembling a plurality of rotor cores for an electric converter. The method includes placing, by a core robotic system employing force control feedback, a rotor core on a mandrel, and for each of the plurality of rotor cores, placing, a plurality of magnetizable inserts into a plurality of cavities in the rotor core by an insert assembly robotic (IAR) system employing force control feedback.

A method of assembling a plurality of rotor cores for an electric converter, the method comprising:
- providing a core robotic system employing force control feedback and an insert assembly robotic (IAR) system;
- placing a rotor core of the plurality of rotor cores on a mandrel by the core robotic system employing force control feedback, wherein each one rotor core from the plurality of rotor cores includes a plurality of cavities;
- and
- placing a plurality of magnetizable inserts into the plurality of cavities of the rotor core by the insert assembly robotic (IAR) system employing force control feedback,
- wherein the IAR system includes a force control end-effector configured to hold one or more magnetizable inserts from the plurality of magnetizable inserts, wherein the placing the plurality of magnetizable inserts further comprises:
- acquiring, by the force control end-effector, the one or more magnetizable inserts:
- aligning the one or more magnetizable inserts with one or more cavities among the plurality of cavities;
- and
- releasing, by the force control end-effector, the one or more magnetizable inserts into the one or more cavities to have the one or more magnetizable inserts independently descend into the one or more cavities.
A method of assembling a plurality of rotor cores for an electric converter, the method comprising:
- providing a core robotic system employing force control feedback and an insert assembly robotic (IAR) system;
- placing a rotor core of the plurality of rotor cores on a mandrel by the core robotic system employing force control feedback, wherein each one rotor core from the plurality of rotor cores includes a plurality of cavities;
- and

- wherein the placing the magnetizable inserts further comprises:
- gripping one or more magnetizable inserts from the plurality of magnetizable inserts by the IAR system at a first orientation;
- and
- aligning and positioning, at a second orientation different from the first orientation, the one or more magnetizable inserts at the one or more cavities among the plurality of cavities based on a force feedback detected by the IAR system.
A method of assembling a plurality of rotor cores for an electric converter, the method comprising:
- providing a core robotic system employing force control feedback and an insert assembly robotic (IAR) system;
- placing a rotor core of the plurality of rotor cores on a mandrel by the core robotic system employing force control feedback, wherein each one rotor core from the plurality of rotor cores includes a plurality of cavities;
- and
- placing a plurality of magnetizable inserts into the plurality of cavities of the rotor core by the insert assembly robotic (IAR) system employing force control feedback,
- wherein the placing the magnetizable inserts further comprises sequentially placing N magnetizable inserts at a time into N cavities among the plurality of cavities, wherein N is a number that is less than a total number of magnetizable inserts to be placed.
