Mathematical Model of Transient Processes 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.
