Abstract

The article presents an assessment of the characteristics of the electric drive of the cold-pilgering mill, in which each phase of the stator motor windings is connected to an independent DC source. The evaluation was performed according to the criterion of maximum speed. A set of mathematical equations with lumped parameters of an electrical machine was adopted as a model, and a semiconductor converter was represented by an aperiodic link of the second order. A synchronous motor based on an asynchronous motor with a phase rotor was used as an electric machine. In an electric car, the stator windings of the motor were connected to a DC source. The rotor windings were connected to a frequency converter. It is shown that the speed of the control circuit of the electromagnetic torque in such a scheme does not exceed 130 rad/s. This speed is limited to the analog-to-digital converter through which the control signal from the output of the speed regulator is fed. To increase the system response speed, it is proposed to generate a control signal via a serial digital channel, for example, Ethernet. The rejection of the analog form of the control signal will significantly increase the accuracy of the electric drive system, while the expected cut-off frequency in the control circuit of the torque can reach 700-800 rad/s.

皮尔金磨电动驱动

本文介绍了冷镦机的电力驱动特性的评估，其中定子电机绕组的每一相连接到一个独立的直流电源。以最大转速为评价标准。采用电机集总参数数学方程组作为模型，将半导体变换器用二阶非周期链路表示。在异步电动机的基础上，采用带相转子的同步电动机作为电机。在电动汽车中，电机的定子绕组连接到直流电源上。转子绕组连接到变频器上。结果表明，该方案的电磁转矩控制电路的速度不超过130 rad/s。这个速度受模数转换器的限制，从调速器输出的控制信号通过模数转换器被馈送。为了提高系统响应速度，建议通过串行数字通道(例如以太网)产生控制信号。抑制模拟形式的控制信号将显著提高电驱动系统的精度，而控制电路中扭矩的预期截止频率可达到700-800 rad/s。
