FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical micro machines, namely to angular acceleration sensors (accelerometers), intended for measurement of angular acceleration of controlled shafts in automation and computer equipment. This invention consists in that accelerometer-tachometer generator comprises stator with poles of excitation in form of permanent magnets and poles with measurement windings and compensation winding, hollow electrically conductive rotor and an amplifier, wherein hollow rotor is made conductive with longitudinal slots with skew in form of windows comparable with pole tips of stator, which is equal to pitch pole division, wherein hollow electrically conductive rotor on sections between longitudinal slots is made of insulated from each other axial plates closed at ends of hollow electrically conductive rotor.
EFFECT: technical result is improved metrological characteristics of accelerometer-tacho generator and high linearity, as well as broader functional capabilities owing to use device as tacho generator and faster operation.
