Electron transport through a three-electrode triple-quantum-dot ring with the source electrode of spin-dependent splitting of chemical potentials (spin bias) is theoretically investigated. We find clear charge and spin currents in the drain electrodes driven by the spin bias, despite the absence of charge bias between the source and drain electrodes, and their directions and amplitudes can be adjusted by altering the structure parameters or magnetic field. The distinct characteristics of spin-bias driven persistent charge and spin currents in the ring are also shown. When an appropriate charge bias is applied, the single-spin electron motion can be achieved in this structure.
