摘　　要：在现有的对称型定量泵、定量马达原理基础上,设计出了双定子对称型结构的多泵/多速马达,在一个壳体内1个转子对应2个定子,使多速马达可以独立同步工作;以双定子对称型双作用多速马达为例,阐述了结构和工作原理,定义了符号表示方法,分析了多泵的输出流量特性、多速马达的输出转速和转矩特性,对多泵多速马达不同组合方式下的多速马达转速进行了分析,结果表明,双定子对称型多速马达能够输出多种不同的转速和转矩,这为双定子多泵/多速马达系统在机床设备、行走机械等领域的应用奠定了基础。A double-stator symmetrical type multi-pump and multi-speed motor is designed based on the principles of existing symmetrical constant pumps and constant motors. In the shell, a rotor is corresponding to two stators, so the multi-speed motor can work independently and synchronously. As an example, we describe the structure and working principle of the double-acting symmetrical-type double- stator multi-speed motor, define its symbolic representation method, and analyze the output flow features of the multi-pump and the output speed and torque features of the multi-speed motor. The speed of the multi-speed motor under different combinations of multi-pump and multi-speed motor is analyzed. The results show symmetric type double-stator multi-speed motor can output many different speeds and torques. The study establishes a basis for applications of double-stator multi-pump and multi-speed motor system on machine tools, mobile machineries and so on.
