Title: Inventor Profile: Johan Abrahamsson
Introduction
Johan Abrahamsson, an innovative inventor based in Uppsala, Sweden, has made significant contributions to the field of electrical machines and electromechanical actuators. With three patents to his name, he is recognized for his creativity and technical expertise in developing advanced solutions that enhance machine performance and control.
Latest Patents
Abrahamsson's latest patents include two groundbreaking inventions. The first is an "Arrangement and method for force compensation in electrical machines." This electrical machine comprises a rotor, a stator, a rotor power supply, and at least one sensor, along with a rotor magnetization control arrangement. The patent involves a system where the rotor is equipped with windings for controlling the magnetization of its magnetic poles. The sensor measures parameters associated with the relative force between the rotor and stator, allowing for precise control of rotor currents based on the measured signals.
The second patent, a "Wide frequency range electromechanical actuator," innovative uses at least two electromechanical actuating elements—bimorph, monomorph, or multimorph—that are interconnected by a common actuator backbone. These actuating elements can be controlled in both a longitudinal and flexural direction, offering versatility in movement. The dimensions of the actuator are optimized for specific resonance frequencies, enabling it to operate effectively for both fine positioning and resonant motion while suppressing the transfer of acoustic waves.
