A series of novel kind of pumps and motors were designed, which were based on a new structure called by double-stator. For double-stator, one rotator corresponds two stators and more than one pump or motor can work alone or be combined just in one shell. After introduced the working principle of double-acting double-stator motor and the definition of symbols, a novel theory named multi-pump and multi-motor hydraulic transmission was proposed. The output torque in a variety of connection for double-acting multi-pump and multi-motor transmission was discussed in details. The results show that this new kind of hydraulic components can better meet the actual requirements and has broadly potential applications.
