Electrodynamic Converter

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes an improved electrodynamic converter (a type of generator) that uses specially arranged "claw disks" and magnetic components to convert mechanical energy into electrical energy. The unique arrangement and angular offset of the rotating parts (claw disks) and their magnetic circuits help reduce mechanical resistance (cogging torque) and make the system efficient and easier to miniaturize. The design is simple, cost-effective to manufacture, and adaptable for small-scale applications requiring autonomous power generation.

• Miniaturized generators for autonomous sensor systems (e.g., industrial or environmental monitoring)
• Energy harvesting in wireless devices or Internet of Things (IoT) applications
• Alternators or small-scale generators for automotive, bicycles, or portable equipment
• Backup or emergency power supplies for small electronics
• Micro-motors or actuators when controlled via external current
• Precision instruments requiring low-cogging torque electrical conversion
• Medical devices or implants that require in-situ energy generation

BenefitsContent extracted from patent full text and abstract with AI.

• Reduced cogging torque (mechanical resistance), resulting in smoother operation and higher efficiency
• Simplified and cost-effective design due to fewer and easier-to-manufacture components
• Enables miniaturization, supporting compact or embedded applications
• Versatility in using either permanent magnets or electromagnets, allowing for different customization options
• Precise assembly and low production tolerances, improving performance consistency
• Potentially higher reliability due to fewer moving parts and wear points
• Can serve both as a generator and, in certain configurations, as a motor

Patent Abstract

The application relates to an electrodynamic converter (1), comprising a coil (11), a claw disk (7) associated with the coil (11) and having a disk component (7a) that can be rotated about an axis of rotation and a disk component (7b) that is stationary relative thereto, comprising a further claw disk (8) associated with the coil (11) and having a disk component (8a) that can be rotated about the axis of rotation and a disk component (8b) that is stationary relative thereto, and comprising magnetic flux components, which have oppositely magnetized magnetic components (9, 10; 12, 13) and magnetic flux elements composed of soft magnetic material, of which at least some are associated with a magnetic flux through the claw disk (7) or a further magnetic flux through the further claw disk (8) during operation, which are formed in alternation as the rotatable disk component (7a) of the claw disk (7) and the rotatable disk component (8a) of the further claw disk (8) are rotated, wherein the magnet-flux-closing relative positions for the claw disk (7) and the further claw disk (8) are formed having an angular offset to each other, as are also non-magnetic relative positions.
