| Summary: | This study considered the issue of increasing the synchronizing capacity of a system for the coordinated rotation of asynchronous motors. Electromechanical relationships were obtained for changes in the value of the supply voltage of individual motors, the total rotor resistance (<i>Ra</i>), and the angular positions of the rotors (<i>φ</i><sub>1</sub>, <i>φ</i><sub>2</sub>, and <i>φ</i><sub>3</sub>), with possible changes in angular misalignment. Additionally, we created an algorithm for calculating the currents and torques of the system’s motors within 0 and 90° and constructed the relevant mechanical characteristics. Ultimately, we developed various versions of multi-motor asynchronous electric drives with regulation and supply voltages (<i>U</i><sub>n</sub> = 0.7 ÷ 1.0), featuring increasing and equalizing torques (<i>M</i><sub>n</sub> = 1.0 ÷ 1.4) in the system as a whole, along with the preliminary synchronization and synchronous braking of all motors. |
