“…Where one of the motion coming from a constant speed motor provides the main power, a small servo motor introduces programmability to the resultant actuator [18] [19]. To combine the piezoelectric motor accuracy with the torque obtainable by a DC motor, it is proposed to realize the differential mechanism drawn in figure 26.…”

“…In his study, the peak power of the servomotor was reduced by approximately 70%. Kirecci and Dulger [13,14] proposed a hybrid actuator, specifically, an arrangement consisting of a planar two-degreesof-freedom, seven-link mechanism driven by a constant speed motor and a servomotor. They studied the dynamic behavior of their hybrid actuator by applying numerical simulations to the whole system.…”

The main feature of hybrid-driven linkage is the combination of the motion of a large constant velocity motor with that of a small servomotor via a two-degrees-of-freedom mechanism. Thereby, the hybrid-driven linkage can provide for programmable motion output. In the present study, a mechanical drawing press driven by a hybrid mechanism was optimized for displacement and velocity. An analysis of forward kinematics and an optimum model are presented. The actual displacement curves of the slider can approach the ideal ones by means of a two-step optimization. The dimensions of the linkage and the motion rules of the servomotor were optimized. The flexible features of the hybrid-driven drawing press are effectively demonstrated by three optimum examples. The optimum results validate the advantages of the hybrid-driven seven-bar mechanical press, such as its flexible slider speeds and adjustable strokes for drawing operations. By properly designing the input motion of the servomotor, the slider can pass through the desired trajectories.

“…However, a servomotor's power capacity usually is limited [3][4][5][6]. Recently, researchers looking for answers have turned to the hybriddriven mechanism [7][8][9][10][11][12][13][14][15][16][17][18][19][20]. The main idea in the hybrid-driven concept is to combine the motion of a large constant-velocity motor with a small servomotor via a two-degrees-of-freedom mechanism.…”

Modeling and dynamic analysis of the electromechanical coupling system of a hybrid-driven mechanical press were undertaken. A dynamic model of a two-degrees-of-freedom seven-bar linkage was developed using Lagrange's equation. According to the equivalent circuit of a DC motor and a brushless servomotor, a dynamic model and negative feed-back model were separately developed. The fourth-order Runge-Kutta method, an explicit method, was employed as the integration technique in a computer simulation, and the time history of the hybrid-driven press was obtained.
