Abstract: Single-acting double-stator motor has four operating states, including inner or outer motor working alone, inner and outer motor united working and differential operating states. Through the calculation of the hydraulic force acting on the rotor in different operating states, the formula of acting force is acquired, the effect of the vane number, which is odd or even, on the acting force is considered. The simulation according to the prototype was carried out using MATLAB. The results show that the rotor radial force varies periodically within a certain range under four strained conditions. Compared with that of the classical vane pumps, the strained conditions of the rotor of single-acting double-stator are better. This study may provide reference for the design of the variable displacement mechanism for single-acting double-stator hydraulic motors.

Key words: fluid transmission and control, double-stator single-acting multi-motor, differential connection, mechanical characteristic
