Abstract
This paper presents design solutions in the development of an electro-hydraulic power amplifier (EHPA) of a servo-hydraulic drive with hydrostatic guides. The work studies the characteristics and develops fundamental solutions to design elements and the general configuration of the EHPA, which is part of the servo-hydraulic drive. The paper analyzes the device, operating principles, and basic requirements for EHPAs. A digital model is built and a basic version of an electromechanical converter (EMC) is tested to assess its electromagnetic and thermal state. As a result of the work, the authors determined and justified the design of the main components of the EMC for the EHPA, developed a digital model for the EMС with permanent-magnet excitation, analyzed its electromagnetic and thermal state, and developed design documentation.
