DC SERVO MOTOR CONTROL SYSTEM TRAINERS DSMC-1   Downloadable Data Sheet       The DC servo motor (DSMC-1) is adopted most widely in the FA fields as a servo mechanism in the age of mechatronics. Especially more compact, light weight, and high output are the demands of the times. The control technology of the PWM servo driver make excellent servo characteristic of DC servo motor. The DC servo control system permits high accuracy and fast rosponse loop system. It has been used in wide variety of operating environments, including : - Robotics and Manipulators - Office machines - Measuring equipments - Machine tool - Military system - Aerospace DSMC-1 is a training system designed to help students learn servo motor control easily. DSMC-1 is intended for use in basic engineering coursework in universities, polytechnic colleges, and technical-vocational schools. It reliably under girds engineering specialities including : - Mechanical - Electrical - Control - Aerospace - Automation - Marine - Vehicle - Robotic The system creates the basic phenomena. System users have hands-on control of their measurements, design and analysis. Teaching, learning and researching become more effectively and quickly done.      FEATURES > 15 experiments that cover DC servo control system, from fundamental analysis to system design. > Function generator and scope software included in DSMC-1 software. No external function generator or storage scope is required. > Menu-driven and intuitively organized software for the optimum user-friendly learning environment. > Real-time on-line computer control to make teaching and learning practical and effective.   TOPICS > Control software-MBSP provides following experiment contents : a.
