SYNCHRONOUS-COPHASED ELECTRIC DRIVE Russian patent published in 2011 - IPC H02P7/06 H02P7/14 H02P7/285 

FIELD: electricity.

SUBSTANCE: in a synchronous-cophased electric drive, a generator of additional pulses is equipped with a non-linear element with an insensitivity area, which makes it possible to increase electric drive efficiency in a phasing mode in the area of low frequency rotation by reduction of phasing cycle duration, and in the area of high rotation frequencies - due to absence of accumulation in cycles of a velocity error phasing. The circuit realisation of a unit for detection of a phase mismatch arranged as specified in the application materials makes it possible to increase its efficiency and accordingly efficiency of an electric drive in the phasing mode due to continuous detection of an angle mismatch as pulses of master frequency and pulses of feedback frequency.

EFFECT: increased efficiency of a synchronous-cophased electric drive in the phasing mode.
