FIELD: electricity.

SUBSTANCE: compartment (2) of the electric motor within the on-load tap changer comprises an electric motor module and a control module (12). The module of the electric motor comprises an electric motor (6), a reducer (7) and a position sensor (9), besides, the control module (12) is made with the possibility to control an output shaft (3), which goes out from the compartment (2) of the electric motor, by means of power supply to the electric motor (6) via a direct connection to put the output shaft (3) in motion via a reducer (7), besides, the position sensor (9) is made with the possibility to register motion and positions of the output shaft (3) and to transfer information about such to the control module (12). The compartment (2) of the electric motor in the working condition is tightly closed with the electric motor module and the control module (12), arranged inside such tightly closed volume.

EFFECT: reduced time for production deployment, increased flexibility for making changes into the order at the later stages of its completion, increased convenience of service, reduced cost of the electric motor for the on-load tap changer.
