Impact of voltage subharmonics and interharmonics on currents in single-phase induction motors
Scientific Journal of Gdynia Maritime University, 2021 In very low power drives, a single-phase induction motor is used. This motor, like the 3-phase induction squirrel-cage motor, requires a voltage supply with suitable parameters – of suitable quality, in practice.

Subharmonics of any order in nonlinear systems of one degree of freedom: application to subharmonics of order 1/3 [PDF]
, 1958 This paper consists of two parts. In the first one we discuss the subharmonics of any order in the case where the nonlinearity enters in the elastic forces. The basic differential equation is with coefficients not necessarily small.
