ROTARY ELECTRICAL MACHINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18578362 titled 'ROTARY ELECTRICAL MACHINE
The abstract describes a rotary electrical machine with a cylindrical stator, a rotor, and a housing. The stator generates a magnetic field, the rotor generates torque, and the housing accommodates the stator.
- The housing consists of a housing body covering the stator's outer circumferential part and a housing lid attached to one end of the housing body.
- The stator includes a stator core with teeth and a stator coil with windings wound onto the teeth, along with a crossover wire connecting some windings.
- The crossover wire has an insertion mechanism on the housing lid part that electrically connects the windings' end parts and the crossover wire's end part through insertion contact.
Potential Applications: - Electric vehicles - Wind turbines - Industrial machinery
Problems Solved: - Efficient generation of torque - Simplified design for electrical machines
Benefits: - Increased efficiency - Reduced maintenance - Enhanced performance
Commercial Applications: Title: "Innovative Rotary Electrical Machine for Various Industrial Applications" This technology can be used in electric vehicles, wind turbines, and other industrial machinery, offering improved efficiency and performance.
Questions about the technology: 1. How does the crossover wire improve the performance of the rotary electrical machine? 2. What are the key advantages of using a cylindrical stator in this type of electrical machine?
Original Abstract Submitted
A rotary electrical machine comprises a cylindrical stator that generates a magnetic field, a rotor that generates torque through the magnetic field, and a housing that accommodates the stator. The housing comprises a housing body covering an outer circumferential part of the stator, and a housing lid part attached to one end side of the housing body. The stator comprises a stator core having a plurality of teeth, and a stator coil mounted on the stator core, and the stator coil has a plurality of windings wound onto the plurality of teeth, and a crossover wire connecting at least two of the plurality of windings. The crossover wire comprises an insertion mechanism that is provided to the housing lid part and electrically connects end parts of the windings and an end part of the crossover wire through insertion contact.
