Abstract

In this paper, we consider new possibilities realized in alternating current electric machines that are designed for controlled electric drives and powered by semiconductor frequency converters. We concentrate on the possibility of improving the technical and economic performance of the system by taking into account the combined work of the semiconductor converter and the engine under development. The design of asynchronous electric machines for a semiconductor converter is shown to allow significantly improve its energy performance and expand the control range in terms of electromagnetic moment. The possibility of improving the mass–dimension parameters of synchronous machines operating in frequency-controlled systems is substantiated. We show that it is possible for these machines to exclude completely loss from synchronism. We established that synchronous reluctance machines can have specific indices close to those of asynchronous motors, and they realize a significantly larger overload torque in this case. Calculated methods for the synthesis of asynchronous electric drives that were successfully tested in the development of a series of main drives of the D423 drilling rig are proposed. These electric machines were designed for mechanisms with a fanlike load (mud pump) and with an active reluctance torque (winch drive). A synthesis method for the SRMTD synchronous reluctance engines that were tested on an engine for a cold pipe rolling mill is developed.

现代受控交流电驱动器电机设计的新方法

摘要

在本文中，我们考虑了设计用于受控电驱动并由半导体变频器供电的交流电机中实现的新可能性。我们将重点放在通过考虑半导体转换器和正在开发的发动机的综合工作来提高系统的技术和经济性能的可能性上。示出了用于半导体转换器的异步电机的设计，其允许显着改善其能量性能并扩展了电磁力矩方面的控制范围。证实了改善在频率控制系统中运行的同步电机的质量参数的可能性。我们证明这些机器有可能完全排除同步损失。我们建立了同步磁阻电机可以具有与异步电动机相近的特定指标，并且在这种情况下，它们可以实现更大的过载转矩。提出了用于合成异步电驱动器的计算方法，该方法已在D423钻机的一系列主驱动器的开发中成功进行了测试。这些电机设计用于具有扇形负载（泥浆泵）和主动磁阻转矩（绞车驱动）的机构。开发了一种用于SRMTD同步磁阻发动机的合成方法，该方法已在冷轧管机的发动机上进行了测试。提出了用于合成异步电驱动器的计算方法，该方法已在D423钻机的一系列主驱动器的开发中成功进行了测试。这些电机设计用于具有扇形负载（泥浆泵）和主动磁阻转矩（绞车驱动）的机构。开发了一种用于SRMTD同步磁阻发动机的合成方法，该方法已在冷轧管机的发动机上进行了测试。提出了用于合成异步电驱动器的计算方法，该方法已在D423钻机的一系列主驱动器的开发中成功进行了测试。这些电机设计用于具有扇形负载（泥浆泵）和主动磁阻转矩（绞车驱动）的机构。开发了一种用于SRMTD同步磁阻发动机的合成方法，该方法已在冷轧管机的发动机上进行了测试。
