Today, intralogistic services have to respond quickly to changing market needs, unforeseeable trends and shorter product life cycles. These drivers pose new demands on intralogistic systems to be highly flexible, rock-solid reliable, self-optimising, quickly deployable and safe yet efficient in environments shared with humans. ILIAD will enable the transition to automation of intralogistic services with key stakeholders from the food distribution sector, where these challenges are particularly pressing. We will develop robotic solutions that can integrate with current warehouse facilities, extending the state of the art to achieve self-deploying fleets of heterogeneous robots in multiple-actor systems; life-long self-optimisation; manipulation from a mobile platform; efficient and safe operation in environments shared with humans; and efficient fleet management with formal guarantees. Scientifically, ILIAD pursues ambitious goals for complex cognitive systems in human environments beyond a specific use-case. We will overcome limitations in the state of the art in tracking and analysing humans; quantifying map quality and predicting future states depending on activity patterns inferred from long-term observations; planning of socially normative movements using learned human models; integration of task allocation, coordination and motion planning for heterogeneous robot fleets; and systematically studying human safety in mixed environments, providing a foundation for future safety standards. Our consortium is uniquely placed to tackle these challenges and to maximise exploitation beyond the projects duration. It includes partners with a proven track record in all key research areas, leading technology providers for intralogistics, end users that are leading in their respective markets, and the National Centre for Food Manufacturing at partner UoL, facilitating access to realistic test sites. This mix of partners will ensure a very high impact of the project results.


A rotor having a plurality of laminations joined together and mountable on a shaft for rotation relative to a stator of a rotary electric machine arrangement has a solid section that surrounds an opening within which the shaft is receivable. The solid section includes an outside diameter, magnet receiving voids, and steps delimiting a plurality of pole spans from flux directing features at sides of each of the pole spans. Adjacent flux directing features between adjacent pole spans are disposed on opposite sides of scalloped areas or other such recesses, permitting cooling air flow past the rotor. The invention also concerns a lamination usable together with additional laminations to provide such a rotor, as well as an arrangement, such as an AC motor, generator, or motor/generator, including a stator and such a rotor.

The present invention relates to a bridge leg (12) switching a DC voltage at its respective input terminal (30, 31) to produce an AC voltage at its output terminal (2) for supply to an inductive load. The bridge leg comprises a first switch assembly (22), a second switch assembly (21), a third switch assembly (24), a fourth switch assembly (23) and at least a first inductive element (51). The first switch assembly (22) and the second switch assembly (21) are serially connected between the bridge leg input terminals (30, 31), the bridge leg output (2) being formed at a point of interconnection of the first switch assembly (22) and the second switch assembly (21). The third switch assembly (24) and the fourth switch assembly (23) are serially connected between the bridge leg input terminals (30, 31), the inductive element (51) being connected between a point of interconnection of the third switch assembly (24) and the fourth switch assembly (23) and the bridge leg output (2). The third switch assembly (24) and the fourth switch assembly (23) are controlled such that reverse current through either of the first switch assembly (22) or the second switch assembly (21) is reduced compared to bridge leg output current prior to the moment of switching of the bridge leg output (2).

The present invention relates to a switched power converter comprising a base plate on which at least one heat sink is arranged. The converter further comprises at least one power transistor arranged on a side of the at least one heat sink. Further, at least one spring element is arranged to press against the power transistor arranged on a side of the at least one heat sink and an oppositely facing side of either an adjacent heat sink or a base plate end face parallel to the at least one heat sink. This is highly advantageous in that a force is applied to the power transistor by the spring element. This will press the power transistor against the heat sink on whose side the transistor is arranged. Thermal contact is thus established between the power transistor and the heat sink, and heat dissipation from the transistor via the heat sink is greatly facilitated. Further, the spring elements are a cost-effective way of attaining a high compressive force on the power transistors.

Patent
Kollmorgen | Date: 2013-02-25

A rotor for an electric motor with improved oscillation settling characteristics has a shaft rotatable about a longitudinal axis, a rotor section, disposed on the shaft for rotation together with the shaft, and, in certain arrangements, a permanent magnet disposed adjacent to the rotor section for rotation together with the shaft. The rotor section defines a recess around the shaft, extending from an end of the rotor section axially toward the opposite end of the rotor section, or the permanent magnet, if it is provided, and at least one mass is secured to the rotor section within the recess by a layer of deformable damping material, such as a dielectric gel. The rotor is particularly appropriate for use in a hybrid stepper motor, a variable reluctance motor, or a permanent magnet brushless motor, and a process of assembling the rotor is also referred to.

A system for providing operating or charging current supply in different modes of operation includes an electric machine including a rotor and a stator having stator windings, at least one charge storage device, such as a battery, and an inverter disposed between the charge storage device terminals and the electric machine. A contact arrangement modifies electrical interconnections between phases of the inverter and the stator windings. In a supply mode, the electrical interconnections are controlled so that each inverter phase is electrically interconnected with a stator winding set having windings separated from each other by stator windings in other winding sets for driving the rotor of the electrical machine. In a charge mode, however, these interconnections are controlled so that each inverter phase is electrically interconnected with a stator winding set having windings directly adjacent to each other and are not separated from each other.
