This article proposes an analytical method for the selection of machine parameters and inverter power ratings of a synchronous motor operated in an open-end winding (OEW) configuration with one of the two voltage-source inverters (VSIs) connected to a floating capacitor (FC) in order to meet a specific torque–speed profile. With the derived normalized expressions and curves, all the suitable synchronous motors operated with an OEW-FC and a standard two-level VSI drive can be easily compared according to the power rating and desired speed–torque characteristic.
