FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and can be used in electric hand tool, household and industrial electrical appliances, and devices for special purpose. In energy-saving control method, a single-phase collector motor with dynamic correction of motion during start-up, control converter generates motor supply voltage at the level of maximum value for the current rise time of the motor, which is in direct ratio to the motor time response, and then forms source voltage in accordance with the required law of control.
EFFECT: technical result is to improve electric drive energy datum, in particular, the dynamic energy efficiency.
