Abstract

The article discusses the issue of creating an energy-saving asynchronous electric drive of oscillatory (reciprocating) motion. The authors note that traditionally, to create this kind of drives, either mechanical gearboxes or supply voltage phase polarity switches are used, which leads to power losses and electromechanical shocks at the moment of reverse. It is proposed to use the principle of self-oscillatory operation of the power electromechanical unit “asynchronous motor - elastic element”. Shown are the connection diagrams of the stator windings to create maximum torque. It is proposed to use not a pendulum or an imbalance as an elastic element, but a system for energy recovery into the network, which will increase the efficiency of the installation due to the return of braking energy. Such a system will provide a soft reverse rotation without electromechanical shocks, as well as the ability to flexibly regulate the parameters of the oscillatory motion. It was concluded that an asynchronous electric drive of oscillatory motion based on a self-oscillatory mode and an energy recovery system will improve energy efficiency compared to traditional schemes with mechanical gearboxes or polarity switches. Using recuperation instead of a pendulum eliminates energy loss due to mechanical imbalance. The proposed connection diagram of the stator windings provides maximum starting torque of the asynchronous motor.
