Inertial Damper for Stepper Motors DMP - PHYTRON - #1

Text version of the page

AMBIENT DMP is an inertial damper for stepper motors. It delivers an excellent performance over a wide frequency because of its specific structure. This minimises settling times in the start-stop operating region and avoids system resonances. Thus, the DMP prevents not only vibrationinduced material fatigue and vibration-induced positioning errors, but also significantly reduces the acoustic noise. If certain perturbances are not adequately compensated for, the motor can lose steps. The resulting loss of torque and precision can drastically affect the application‘s performance. phytron‘s stepper motors run very smoothly due to their construction, hence a damper is not needed for most precision applications. However, should a Phytron motor operate in a resonance range, the damper is easily deployed to further enhance the motor‘s characteristics and stability. Application Greater requirements for smooth running and precision are often necessary, especially in optics. When moving samples or optics via a joystick, the improvements in the move quality for smoothness, very low acoustic noise and precision are visibly and audibly attained. Accurate and consistent movements with fast settling times of the driven system are significantly improved.
