Failure of ProFile instruments used with air, high torque control, and low torque control motors.
OBJECTIVE The purpose of this study was to evaluate the influence of 350-rpm rotational speed on the failure incidence of ProFile nickel-titanium rotary instruments (PRI) when used by an experienced operator in conjunction with different motors. STUDY DESIGN Extracted human mandibular and maxillary first and second molars demonstrating curvatures greater than 25 degrees were used. PRI sizes 4...
متن کاملTorque ripple and misalignment torque compensation for the built-in torque sensor of harmonic drive systems
A harmonic drive is a compact, lightweight, and high-ratio torque transmission device which is used in many electrically actuated robot manipulators. In this paper a builtin torque sensor for harmonic-drive systems is examined in detail. The method proposed by Hashimoto, in which strain gauges are directly mounted on the flexspline, is employed and improved in this paper. To minimize sensing in...
متن کاملTorque ripple minimization in direct-drive systems
The open-loop torque control of synchronous motors with minimum torque ripple and minimum copper losses is presented. The control problem is viewed as an optimization problem for the nonlinear mapping from desired torque and position to the motor's phase currents. The performance of the controller to produce virtually ripple-free torque and to enhance the precision of position tracking is demon...

A harmonic drive is a compact light weight and high ratio torque transmission device which has almost zero backlash Its unique performance features has captured the attention of designers in many industrial applications especially in robotics Despite widespread industrial application of harmonic drives the torque control of this system has not been fully addressed In this thesis the robust torq...
متن کاملDevelopment of Limited Angle Brushless Torque Motor Control Drive for Scan Mirror Mechanism
This paper illustrate the design and realization of control drive electronics of Limited Angle brushless torque motor for position control of Scan mirror mechanism. The scan mirror mechanism is controlled for the intended limited mechanical angle within +/20deg. The control drive is designed for six selectable positions within +/20deg with an accuracy of 0.75 degree. These six selectable positi...
