FIELD: electricity.;SUBSTANCE: controller design of the electromotor includes a base that performs the function of the ground on which the motor phase control units are installed. Each control unit contains a ground bus, a phase bus, a positive bus and a series of electronic current control elements located between the buses and being collapsed into a single package along with the said buses. The buses are installed in parallel on the base. The phase bus and the positive bus are mounted on the housing through non-conductive elements. A printed-wiring board of the control circuit of the electronic control elements, as well as switching connections between electronic control elements and areas of pressing of buses to a board is installed on the buses. The positive buses of the control units are connected to the positive input of the power supply by means of a busbar, pressed to the end of the positive buses and consisting of plates. The design of the connection unit of electrical buses includes a series of flat buses interconnected by means of a busbar pressed to the end of each of the flat buses by pressing devices.;EFFECT: increase the reliability of the electromotor controller at high switching currents.;14 cl, 8 dwg
