ELECTRIC MACHINE END WINDING DESIGN WITHOUT CONDUCTOR OVERLAP - A simplified explanation of the abstract
This abstract first appeared for US patent application 18086855 titled 'ELECTRIC MACHINE END WINDING DESIGN WITHOUT CONDUCTOR OVERLAP
The patent application describes an electric machine with a unique winding design that improves efficiency and performance.
- The winding in the machine has three phases, each with at least two parallel paths made of hurdle-shaped conductors.
- These conductors are interconnected to form continuous circuits between terminals and a neutral point.
- The hurdle-shaped conductors have first and second uprights in different slots of the stator core, connected by a bridge that extends over the core's end surface.
- The bridges are stacked in upper and lower layers, with variable thickness to accommodate the winding design.
- The number of bridges in each layer exceeds the radial positions of the slots, optimizing the winding configuration.
Potential Applications: - Electric motors - Generators - Wind turbines
Problems Solved: - Improved efficiency in electric machines - Enhanced performance and reliability - Optimal use of space in the stator core
Benefits: - Increased energy efficiency - Reduced maintenance requirements - Enhanced power output
Commercial Applications: Electric machine manufacturers can utilize this innovative winding design to create more efficient and reliable products, catering to various industries such as automotive, aerospace, and renewable energy.
Questions about the technology: 1. How does the unique winding design impact the overall performance of the electric machine? 2. What are the potential cost savings associated with implementing this winding design in electric machines?
Original Abstract Submitted
An electric machine includes a stator core defining slots having a number of radial positions. A winding is disposed in the core and has three phases, each of the phases having at least two parallel paths including hurdle-shaped conductors interconnected to form at least two continuous circuits between a terminal and a neutral. Each of the hurdle-shaped conductors have first and second uprights disposed in a different one of the slots and a bridge connecting between the uprights and extending circumferentially over an end surface of the core, wherein the bridges are stacked one on top of the other such that the winding has upper and lower layers. The bridges have variable thickness such that a number of bridges, at each of the upper and lower layers, extending over one of the slots exceeds the number of radial positions of that slot.
