stepping motor การใช้

• During the 1990s, some manufacturers began using computer-controlled servo stepping motors.
• Some of these watches, such as chronographs, contain more than one stepping motor.
• The position of the SQUID is usually controlled by some form of electric stepping motor.
• Compounds were often motorized with micro-stepping motors to allow for smooth programmable and repeatable positioning.
• ST Robotics uses technology which is based on hybrid stepping motors as opposed to the more usual DC servo motors.
• It helped to know about stepping motors and who was building the best drives to keep your telescope tracking your object.
• The camera supports Canon s Stepping Motor ( STM ) lenses, which significantly reduce focus motor noise from the lens.
• These piezoelectric motors are fundamentally stepping motors, with each step comprising either two or three actions, based on the locking type.
• ZGC offers brushless DC motors, stepping motors, PM DC Planetary gear motors, PM DC spur gear motors, LED drivers etc.
• In August 2013 a new version of the lens was announced, featuring a revised optical formula and Canon's STM ( stepping motor ) technology.
• So-called quartz analog wristwatches contain the smallest commonplace stepping motors; they have one coil, draw very little power, and have a PM rotor.
• The active helicases, in contrast, are conceptualized as stepping motors-also known as powerstroke motors-utilizing either a conformational " inch worm " or a hand-over-hand " walking " mechanism to progress.
• This is called " closed loop control " which differs from servo control in that the stepping motors run essentially an open loop  the loop is only closed at the end of each movement of the arm.
• The 700D, however, was introduced with a new kit lens a new version of the existing STM ( stepping motor ) technology and also ( for the first time in a Canon 18 55mm lens ) has a front section that does not rotate.
• The telautograph, an analog precursor to the modern fax machine, transmits electrical impulses recorded by potentiometers at the sending station to stepping motors attached to a pen at the receiving station, thus reproducing at the receiving station a drawing or signature made by sender.
• Combining optical and mechanical effects, the special effects that Howard, Kubrick, and other experts refined and collaborated on * " multiplied technical innovations : the intensive use of front projection for the landscapes in " The Dawn of Man " or the invention of stepping motors servo-controlled by computer for moving the spaceships ."
• In modern quartz clocks, the quartz crystal resonator or oscillator is in the shape of a small tuning fork, laser-trimmed or precision lapped to vibrate at 32, 768 metal oxide semiconductor ( MOS ) integrated circuits allowed a 12-month battery life from a single coin cell when driving either a mechanical Lavet type stepping motor or a liquid crystal display ( in an LCD digital watch ).
