FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, specifically to an electric drive. When phasing a motor shaft, method includes generating pulses FOS at output of DPR (15) and phasing pulses FOP at output of DC (4). When comparing FOS and FOP unit (9) of phase mismatch determines value of angular mismatch Δα. When comparing fOP and fOS value of phase mismatch γ=Δϕ. At outputs of controlled frequency dividers (2, 3), frequency fOP is generated for controlling electric motor (12) and frequency fP = fOP/2. If fP < fOS value |ΔfP|≤0.02fP. If fP < fOP value fP = fOP. Computing device (14) generates Δω mismatch value at angular velocity, as well as signals of setting N1 and N2 for controlled frequency dividers (2, 3). Based on processing values Δα and Δω control unit (13) switches electric motor (12) to braking mode or to motive mode.
EFFECT: technical result consists in reduction of measurement error of phase mismatch of rotating shaft of electric motor.
