single-phase commutator motor

Due to the simplicity of the design and the possibility of obtaining significant rotation frequencies (up to 20,000 - 30,000 rpm) and large starting torques, single-phase commutator motors (SPCM) with series excitation continue to be promising for use in household electrical appliances and hand-held electric tools. During the design of new samples of SPCM, as well as modernization of existing engines of this type, it is necessary to use adequate mathematical models of SPCM, which determines the relevance of the study.

Single-phase commutator motors (SPCM) with sequential excitation have a simple design and low cost, and therefore promising for use in the drive of household appliances and electric hand tools. This necessitates the creation of mathematical models of SPCM, which would allow both the development of new and modernization of existing models of such motors. The aim of the article is to create an engineering mathematical model of the magnetic state of SPCM using circular methods.
