摘要： Described is a rotor of an electric motor, having at least one half-shell which includes a hollow-cylindrical, radially inner region, a hollow-cylindrical, radially outer region, and a toroidal region which in the radial direction and in the circumferential direction extends between the radially inner region and the radially outer region. The toroidal region connects the radial regions to one another. The radially inner region is able to be co-rotationally connected to the electric motor. Additionally, the radially inner region, the radially outer region and the toroidal region are integrally embodied. The half-shell is reinforced by a separate component which is fixedly connected to the half-shell and comprises webs which extend between the radially inner region and the radially outer region. Furthermore proposed are a method for producing the rotor and a method for producing the half-shell of the rotor.

摘要： A surface magnet rotor includes a shaft member extending along a rotational axis, and a magnet portion formed around the shaft member and forming opposite magnetic poles arranged along a circumferential direction. A cross-section of the shaft member includes an intermediate line extending from the rotational axis to a center point in the circumferential direction between a d-axis and a q-axis of the magnet portion. In the cross-section, a first cross-sectional area delimited by the d-axis and the intermediate line is different from a second cross-sectional area delimited by the q-axis and the intermediate line.

摘要： A robot device includes a first link and a second link coupled to the first link via an elbow. One or more of the first link or the second link rotates about an axis of the elbow. The robot device further includes a generator disposed in the elbow. The generator is configured to generate electrical power based on relative angular mechanical movement associated with the elbow. The robot device further includes an end effector configured to transport a substrate within a substrate processing system. The end effector is disposed at a distal end of the second link. The end effector is to receive the electrical power generated by the generator.
