Annotation: The article presents the conclusion of analytical dependences characterising the conditions of optimal energy loss in an asynchronous electric motor for starting a machine unit equipped with an adjustable sliding link. It is shown that in the case of using adjustable sliding links in the kinematic drive chain and with significant inertia of the driven links, it is advisable to withstand the conditions of optimal start-up of the machine unit in terms of energy losses in the electric motor. To fulfill these conditions, it is necessary to maintain the high-speed mode of the asynchronous electric motor at the second stage of starting the machine unit, in which the energy losses in the asynchronous motor, on which its heating depends, will be minimal. Taking into account all factors affecting the movement of the adjustable sliding links will reduce the intensity of the machine unit start-up process.
Keywords: machine unit, start-up, energy loss, asynchronous motor, critical slip, torque, adjustable sliding link
