High Torque Density and Low Torque Ripple Actuator System |
摘要 |
A permanent magnet electric machine drive system that includes a plurality of magnets for generating a first magnetic field and a stator is disposed radially outward from the plurality of magnets for generating a magnetic field. The stator includes a plurality of stator poles separated by slots with each respective stator pole having a concentrated winding with a respective number of turns formed around each respective stator pole. Each respective concentrated winding within the stator comprising non-overlapping phases. The concentrated windings form a dual three-phase winding configuration that includes a first set of three-balanced phase windings and a second set of three-balanced phase windings. The first set of three-balanced phase windings is phase shifted in the range of 15 to 45 electrical degrees from the second set of three-balanced phase windings for reducing the torque ripple. |
