METHOD OF MEASUREMENT OF ERROR OF ANGLE-PARAMETER-CODE CONVERTER BASED ON BODYLESS INFORMATION ELECTRIC MACHINE AND DEVICE FOR ITS REALIZATION Russian patent published in 1994 - IPC

FIELD: automatics, measurement technology. SUBSTANCE: rotor of bodyless information electric machine (IEM) is jointed to shaft and rotary part of protractor with which aid rotor of IEM is turned till new value of digital code will appear. Angle coordinate is registered and compared with its rated value to make conclusion about error of angle-parameter-code converter. Before turn of rotor controlled displacement of stator of IEM with respect to rotor is performed in turn by two mutually perpendicular axes to obtain either alignment of center of bore of stator with that of rotor or their misalignment for designed value ε (for instance, allowance for eccentricity). Device for measurement of error of angle-parameter-code converter has converter of signals of IEM to digital code, device for control over digital code, protractor with shaft to mount rotor of IEM, platform put on frame via dielectric spacer, two rotary plates intended for mutual displacement of rotor and stator of IEM along two perpendicular directions, means to provide for these displacements, displacement indicator and indicator of limit displacements. Stator of IEM is attached to one of rotary plates. EFFECT: increased accuracy of measurement of error of angle-parameter-code converter. 4 cl, 1 dwg
