The first kind of compound gear rotator motor is a new type of hydraulic gear motor in which the engaging power is zero. The structure and the working principle of this type of motor were introduced and its torque uniformity, as one of the important performance parameters of the motor, depends on the movement regularity of the engaged points. The instantaneous torque characteristics and torque pulsation of the motor were analyzed. The conclusion was drawn that the torque pulsation rate of the motor was much smaller than that of common gear motor, the new kind of motor had a bigger displacement are obtained and under some conditions it could be used in a pure water hydraulic drive.
