| 摘要 |
A high acceleration rotary actuator motor assembly is provided comprising a plurality of phase motor elements provided in tandem on a shaft, each phase element including a rotor carrying magnets which alternate exposed poles, the rotor being connected to the shaft and surrounded by a stator formed of a plurality of interconnected segmented stator elements having a contiguous winding to form four magnetic poles, the stator being in electrical communication with a phase electric drive unit, wherein each of the poles exert a magnetic force upon the magnets carried by the rotor when the poles are electrically charged by the phase electric drive unit. The rotors and magnets of each phase motor element are offset about the shaft from one another. In addition, the phase motor elements are electrically isolated from one another. |
