Title: Controller for variable displacement pump and motor capacity
Inventor: MURAKAMI HIROAKI
IPC: F03C1/40
Filed: 1992-08-27
Abstract: PURPOSE:To embody excellent speed change characteristics only with an improved displacement controller by bringing a separate advancing/retreating member into elastic contact with an operating end, and operating the advancing/retreating member so as to be connected or disconnected to/from the operating end freely. CONSTITUTION:When a change nut 10 is displaced by a driving system 11, for example, from the end edge to the start edge, an operating edge 7c is dislocated integratedly with a nut 10 which is energized by a spring 9, so the range of infinity >i>=Dp/Dm of the speed ratio (i) can be attained. (Dp, Dm are the maximum displacement of a pump and a motor respectively.) If driving by the driving system 11 is continued under this condition, the operating edge 7c is held at the start edge, and the nut 10 is disconnected from the operating edge 7c, so that the movement of the nut 10 is converted into the movement of a sub-control rod 12 through a movement conversion system 13, and the rod 12 is projected from a housing 8b to begin decreasing the eccentric ratio (em) of the motor. Therefore, the speed ratio (i) is continuously controlled between -Dp/Dm>i>-infinity  sequentially, so it is possible to control the speed ratio (i) in the range of infinity >i>-infinity .

IPC: H04N5/232
Filed: 1993-08-23
Abstract: PURPOSE:To reduce consumption of a current and the generation of noise when a motor rotates at low speed by calculating an optimum rotation torque while detecting the start of the motor, and performing self correction so as to provided optimum torque characteristics. CONSTITUTION:A voltage to be impressed to drivers 10b and 11b is increased from the bottom value DELTAV by DELTAV and stored in a memory 9b while containing a margin component with the point of starting the rotation of stepping motors 10a and 11a as a rotating operation critical point. Next, the revolving speed of the motors 10a and 11a is discriminated and when this speed is lower than a maximum value, the revolving speed is gradually accelerated DELTASP by DELTASP until the speed becomes the maximum value. Thus, a torque correction is calculated. By using this curve as a memory look-up table and controlling the drive of the motors 10a and 11a, the optimum torque corresponding to the revolving speed can be generated while being designated from the outside. On the other hand, even when the weight is changed by mounting the other parts of a movable part and the torque value is changed, it can be corrected into the optimum torque by similarly calculating the torque correction curve again.
