  • Transforming Axis of Rotation in X, Y, ? System (.pdf)
    of rotation to any point in the X-Y. coordinate system. For example, from Figure 2, assume that the desired axis of rotation. is at point A. - 1 -. Galil Motion Control, Inc. • 3750 Atherton Road • Rocklin, CA 95765 USA • 800-377-6329 • Ph: 916-626-0101 • Fax: 916-626-0102 • xA. θx. Y. X.
  • Smooth rotation
    An adaptive algorithm kills jerky motions in motors. Cogging action boosts position errors in motion-control systems as shown by the position-error graph on the top. The harmonic graph on the bottom identifies specific bands of harmonic frequencies generated by motor cogging. The test system used
  • Original Equipment Manufacturer Moore Controls Used Festo HGPLE Electric Grippers to Help an Automaker's Transmission Operations Eliminate Costly Changeovers
    ISO cylinders for horizontal and vertical part rotation; Festo VTSA valve terminals; and MS-Series air-preparation components. At each cell a motor controller communicates directly to a Siemens programmable logic controller (PLC) via Profibus network using the ProfiSafe machine safety protocol
  • Basics of Servomotor Control (.pdf)
    motors produce more noise and vibration than servomotors. (3) Stepper motors are not suitable for high-speed rotation. Basics of servomotor control 050325.doc. Basic of servomotor control. Nippon Pulse Motor Co.,Ltd. Table of contents. I. Connection and operation differences in stepper motors
  • Control in the refining process
    ) The load carrying capacity will be dependent on the stock being treated (see pulp/refiner interactions). There have been proposals to control refining by gap measurement, but as yet no commercial application exists. A major problem would be the effect of heat. 3.3 Rotation speed Most refiners have fixed
  • Mathematics of Electronic Motor Control
    usable after rotation has been established, this technique has the advantage that it requires no sensors. Figures 3A and 3B provide a control flow overview of both sinusoidal commutation and field oriented control. They differ significantly in that sinusoidal commutation “vectorizes” the motor torque

AN894. CURRENT SENSORS. applications. A summary of the advantages and. disadvantages of each of the current sensors
  • Servo Control of a DC Brush Motor
    Disturbance Rejection. Sequential encoders produce quadrature pulse trains,. from which position, speed, and direction of the motor. SYSTEM OVERVIEW. rotation can be derived. The frequency is proportional. to speed and each transition of F1 and F2 represents. DC Servo Control. an increment of position
