摘要

随着液压技术的飞速发展,对液压马达的类型和性能提出了更高的要求。在实际工作状态下,电机需要有多个稳定的转矩和转矩输出,而现有的电机无法实现。为了解决这一问题,开发了一系列基于双转子结构的新型液压马达,从而进一步开发了等宽曲线双转子偏心壳多速马达。一个定子和两个转子相互配合,通过不同的输入进入。出油口的连接可输出多种不同的转速和转矩,实现了多台电机在一个壳体内同步工作、相互独立工作的功能。本文主要介绍了电机的结构特点和工作原理,推导了电机单独工作和组合工作时的瞬时转矩和转矩脉动系数。同时,为了更直观地了解内外电机转矩脉动规律,利用Matlab软件对电机转矩进行了分析和验证。结果表明,该电机可实现多种不同转速和转矩分析。同时,通过对瞬时转矩和转矩脉动系数的分析,得出内外电机组合的瞬时转矩输出变化规律最好,转矩波动最小。

Torque Ripple Analysis of Double Rotor Eccentric Shell Rotating Multi-Speed Motor with Equal Width Curve
With the rapid development of hydraulic technology, the type and performance of hydraulic motor are put forward higher requirements. In the actual working condition, the motor needs to have more than one stable torque and torque output, but the existing motor cannot be realized. In order to solve this problem, a series of new hydraulic motors based on double rotor structure are developed, thus further developing the multi-speed motor with equal width curve double rotor eccentric shell. One stator and two rotors cooperate with each other and enter through different inputs. The connection of the oil outlet can output a variety of different speed and torque, which realizes the function that multiple motors work synchronously and independently of each other in one shell. This paper mainly introduces the structural characteristics and working principle of the motor, and deduces the instantaneous torque and torque pulsation coefficient of the motor when working alone and in combination. At the same time, in order to understand the torque pulsation law of the internal and external motor more intuitively, the torque of the motor is analyzed and verified by Matlab software. It is concluded that the motor can realize many different speed and torque analysis. At the same time, through the analysis of instantaneous torque and torque pulsation coefficient, it can be concluded that the variation law of instantaneous torque output of internal and external motor combination is the best and the torque fluctuation is the smallest compared with that of internal and external motor alone.
