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

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.
