Magnetic field of a dc motor with excitation from permanent magnets
Currently, DC motors with excitation from permanent magnets ( PM DC) are widely used in vehicles, household appliances, portable power tools due to their simple design and low cost. Therefore, the task of creating mathematical models for their calculation, which can be used for design, is urgent. The purpose of the article is to clarify the mathematical model of the magnetic state of the PM DC and experimental verification of the correspondence of the experimental results to the calculation results.
