摘要：
FIELD: electrical engineering.SUBSTANCE: invention relates to the field of electrical engineering and can be used in high-precision electric drives of scanning systems. In the method for phasing the rotating shaft of an electric motor, the device for implementation thereof includes two NOR gates. Output of first NOR gate is connected to the first output of a pulse frequency-phase discriminator. Second inputs of the first and second NOR gates are respectively connected to the first and second outputs of the phase difference detecting unit. Output of the first NOR gate is connected to the first input of the second NOR gate, whose output is connected to the input of the amplifying-correcting device.EFFECT: technical result is higher reliability of the electric drive in phasing mode.2 cl, 2 dwg
