FIELD: electricity.
SUBSTANCE: speed adapter for the asynchronous engine consists of two and more rectifiers connected in parallel by two bars among themselves and terminals of storage capacity or the storage battery, forming a contour of direct current to which the inverter 3 is connected to the control circuit with the microcontroller, connected to the outline of the direct current, which has feedback with the control electric motors and the linear switch, established on the independent input feeding lines.
EFFECT: achievement of steady work of a drive during voltage drops lower or the switching-off of the network feed.
