Completion and operational testing of the Adams' permanent magnet electric D.C. motor-generator

Abstract

This paper focuses on description of the operation principle inherent to the Adams' electric motor-generator fitted with permanent magnets made of rare earth (NdFeB). There is a certain part dedicated to distribution of the magnetic field within the magnetic circuit of rotor and stator monitoring by means of the Ansys Workbench software. The Adams' motor generator is basically assembled with slight deviations from the original patent with respect to the stator magnetic circuit design. The resultant speed-torque characteristics obtained by measurement and the input power values have been processed to determine the machine's efficiency.
