【 摘 要 】

The article systematizes information on the structure of regulation of non-contact agricultural electric drives with improved mass-size parameters. Regulatory structures with independent control two-zone speed control and sequential excitation are proposed. It is shown that the best indicators are achieved in the scheme of sequential excitation and they reach values of 20-25%. Attention is drawn to the fact that structures with independent excitation are most relevant for dynamic mechanisms that realize the trajectory of motion with the maximum speed. Schemes of sequential excitation are most relevant for mechanisms with a large range of load variations on the motor shaft, for example, agricultural facilities. Schemes with two-zone speed control are most relevant for mechanisms that, with a large increase in speed, significantly reduce the load on the motor shaft.
