Motor of electrical machinery type and micro stepping drive of especially piezoelectric type

摘要

As for the micro stepping motor which is due to this invention, drive element (101,102) of two electrical machinery types which possess the action direction which almost is directed mutually perpendicularly, it has possessed the especially piezo bend transmitter. These actuators (101,102) operate in the drive ring (1), turn the shaft (208) because of this. These actuators (101,102), the drive ring which is located inside (1) and the frame (4) and the outer frame of the U shape of character (6) had, torsional rigidity, through the entire structure (drive module) of the frame shape which is complicated mutually the inside and outside, with non radial you are stuck in the drive ring (1). Drive module you can obtain the compact drive which is formed as one unit as an injection molding part.
