Description

technical field [0001] The invention relates to a multi-dimensional manipulator drive device, in particular to a direct drive motor drive device for joint rotation of a multi-dimensional manipulator used in semiconductor special equipment. Background technique [0002] In the manufacturing process of semiconductor special equipment, it is a key technology to realize the automatic transmission of silicon wafers with multi-dimensional manipulators. Multi-dimensional manipulators generally have more than two rotating joints, and a motor drive device is arranged on each joint to drive the joints to rotate. The motion trajectory of the end of the manipulator is the synthesis of several joint motions. The end of the traditional manipulator has a large amount of data calculation during transmission, and the cost of the motion system is high. The traditional motor drive device has a loose structure, low precision, and is not easy to control. Contents of the invention [0003] The...
