silnik momentowy Explanation: propozycja -------------------------------------------------- Note added at 21 hrs (2015-05-28 00:17:50 GMT) -------------------------------------------------- Compare the pictures Limited Angle Torque Motors Simply stated, a current carrying conductor placed in a magnetic field will have a force (or torque) exerted upon it. This force is proportional to the direction and magnitude of the current and the flux density field. Since the permanent magnet flux density field is fixed, the direction of the rotation depends on the polarity of input current and the amount of torque that is produced is directly proportional to the magnitude of the input current. A DC linear servo amplifier is required to provide power to the torquer. The torquers are typically supplied unhoused without bearings or a shaft, but can be supplied housed if required. Coupling the torquer to your bearing system and a rotary encoder or other feedback device yields a system that is capable of intricate angular position, velocity, and acceleration control. Low moving inertia of the rotor assembly allows for high angular acceleration of the payload. http://www.h2wtech.com/category/limited-angle-torque#product... Silniki momentowe w ofercie Mitsubishi Electric Rodzina serwonapędów MR-J3 została poszerzona o silniki momentowe w zabudowie kompaktowej. Dostępnych jest 12 nowych napędów w zakresie momentów od 6 do 720Nm oraz średnicach zewnętrznych od 130 do 330mm. Silnik momentowy zapewnia dużą sztywność i dynamikę pracy. Dodatkowo enkoder o rozdzielczości 1 MLN (!) pulsów na obrót zapewnia niesamowitą precyzję. Konstrukcja tego typu nie wymaga stosowania dodatkowej przekładni mechanicznej, w ten sposób eliminowane są luzy oraz podnoszona jest całkowita sprawność układu. Wał drążony umożliwia prowadzanie przewodów wprost przez korpus silnik http://www.utrzymanieruchu.pl/menu-gorne/artykul/article/sil... |
