摘要： A servo motor control apparatus comprises a motion control unit for generating a position command; a first drive amplifier connecting with the motion control unit, for receiving the command to drive a first servo motor, and forming a first position control loop together with the motion control unit and the first servo motor; and at least one second drive amplifier connecting with the motion control unit, for receiving the command to drive at least one second servo motor, and forming a second position control loop together with the motion control unit and the second servo motor. The motion control unit comprises at least one synchronous controller, which receives and performs calculations to a difference value between position errors of the first and second position control loops for serving as speed and torque feed forward compensations to keep said second servo motor synchronous with the first servo motor.

摘要： A method and apparatus for mold protection of motor-driven clamping unit is provided. The method and apparatus is based on high response characteristics of the motor and a new control method. A continuously variable restrictive motor output scheme is used in conjunction with the mechanics characteristics of the toggle mechanism to maintain a substantially constant mold protective force at all positions. Further, the mold protective force can be adaptively adjusted with respect to different types of molds and motional conditions so that the mold can be adequately protected whenever abnormal condition occurs during mold closing action. The motor output will thus not unduly increased to a great level that would damage the mold, the machine, or even the operators. The drawbacks of the prior art are thus eliminated.

摘要： A power transmission and pedal force sensing system for an electric motor includes an electric motor, a gear reduction train, a pedal force sensing system, and a power combination mechanism. These four mechanisms are concentrically, closely mounted in a single casing. The pedal force sensing system includes a pedal force transmitting sleeve having an elastic device mounted therein, and a pedal force sensing sleeve mounted outside the pedal force transmission path for converting the pedal force into an axial displacement. A proximity sensor is used to detect the axial displacement and outputs a voltage signal representing the magnitude of the pedal force. The power transmission path is shortened and only one casing is required to house all of the elements to thereby obtain a structure of a higher transmission efficiency and reduced volume and weight.
