Title:
回転と軸方向運動のための電動機
Document Type and Number:
Japanese Patent JP2008524975
Kind Code:
A
Abstract:
The invention relates to a combination drive with a short axial length and a high magnetic capacity. According to the invention, an electric motor comprises a rotational drive device with an outer rotor (AR), and a linear drive device with an outer rotor (AT) or an inner rotor with bearings in the active part. The outer rotor (AR,AT) can be mounted by means of hydrostatic bearings (L1,L2), indirectly by means of a shaft (W), on the stators (SR,ST) of the two drives. Said bearings (L1,L2) are axially arranged inside the outer rotors (AR, AT), presenting a short structural form of the combination drive. Furthermore, the bearings are not located in the magnetic action interstice of the drives, so that they do not influence the capacity of the machine.
