HomeVariable frequency drive
Shaft voltage is not produced by the harmonic voltages and currents in the stator windings being supplied from a VFD; however, for VFDs with high frequency PWM carriers, the distributed capacitance will look like a low impedance pathway and can produce a greater shaft voltage than that produced in a similar direct drive machine. It is important to note that shaft voltage can be produced in non-VFD applications as well as in DC machines and has been observed in both motor and generator applications.
