Web20 Mar 2014 · A Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. Other names for a VFD are variable speed drive , adjustable speed drive , adjustable frequency drive , AC drive , microdrive, and inverter. WebThe paper presents the problem of the relation between ac voltage frequency supplying a circuit and the resulting current frequency in that circuit in the case when the voltage frequency changes smoothly following a $${f}_{{v}}\\left(t\\right)$$ f v t function. Contrary to the expectations, the resulting current frequency fc(t) changes in a different way that … epson s3290 ドライバ
