  • Selecting Miniature Motors for your Medical Device (.pdf)
    - Disc Magnet Technology. As with the BLDC motor, stepper motors can be driven in different ways: ·Openloopinfullstep,halfstepormicrosteppingmode.Inthiscase,nopositioninformationisneeded--therotor. follows the magnetic flux generated by the coils. A linear combination of current in each phase allows
  • Development of Electromotive Force
    of the coils are contacting the "brushes", and current flows through the coil. The interaction of the current flow in coil segment CD with the magnetic field produces a force. upward on segment CD. The current flowing through segment AB interacts with the magnetic field to produce a force downward
  • Basic Gyroscope Spin Motor Excitation Requirements For USD Gyroscopes
    This applications note discusses basic gyroscope spin motor excitation requirements for many models of US Dynamics miniature Rate Integrating Gyroscopes (RIG) and Rate Gyroscopes. Most US Dynamics miniature gyroscopes utilize 2 phase synchronous (hysteresis) motors to drive the gyroscope inertia
  • SQUIGGLE Motor Applications for Whole Body Small Animal MRI
    unpredictably or to become permanently damaged. To overcome these problems, our laboratory has made use of a piezoelectric motor or SQUIGGLE motor. This miniature ultrasonic motor does not generate magnetic fields and can be constructed entirely of non-ferrous materials. The potential utility of the SQUIGGLE
  • Mini valve features high flow
    flow rates exceed that of other miniature solenoid valves in its class largely because the coil and body are combined in a single unit with a unique, flow design. Conventional valves have separate coils and bodies. Energizing the X-Valve shifts a stainless-steel plunger and directs flow. A key
  • Demystifying Linear Motor Integration
    configuration consists of a single-sided stationary magnet track and a moving motor coil or forcer. The iron core maximizes the generated thrust force, and creates a magnetic attraction force between the coil and magnets. This magnetic attraction force can be used to effectively increase the rigidity
  • Vehicle Detection Using AMR Sensors
    of ferrous metals in their chassis. (iron, steel, nickel, cobalt, etc.), magnetic sensors are a. good candidate for detecting vehicles. Today, most. Figure 1 - Earth's Magnetic Field Through Vehicle. magnetic sensor technologies are fairly miniature in size,. and thanks to solid state technology, both

    the transducer null position. Half Bridge, LVDT and digital transducers. The linear Variable Differential Transformer (LVDT) and Half-Bridge are two alternative approaches to the coil format and are described in this section. LVDT and Half-Bridge transducers convert the movement of a core within the magnetic
