  • Maximum High-Voltage and Insulating Resistance for Transformers, Restrictors and More
    Electromagnetic coils are used in the automotive industry as well as in the manufacture of household appliances and in the aerospace industry. Suitable vacuum impregnation and encapsulation processes help protect the electromagnetic coils from corrosion and improve their electrical and mechanical
  • How to Calibrate the Electromagnetic Flowmeter?
    In the process of flowmeter production, multiple steps such as coil winding, lining processing, and electrode assembly are required. This series of operations will cause certain errors and dispersion of the equipment, so a calibration process is required to correct the accuracy. The calibration
  • The Reed Switch used as a Reed Relay (.pdf)
    In a Reed Relay, the Reed Switch uses an electromagnetic coil for activation and is shown in its simplest form in Figure # 1. Reed Relays require relatively little power to operate and are generally gated using transistors, TTL directly or cmos drivers. Reed Relay contacts, when switched dry

  • DC Motors: Principle of Operation
    . Magnetic Flux - A motor can have a fixed wound coil or a permanent magnet stator and a moving wound coil armature or PM rotor that will have interacting magnetic flux fields to produce a force and motion. Force - The amount of current that flows through the electromagnetic field is proportional
  • The History of the Rotary Solenoid
    to rotary motion. When power is applied, it rotates a ratcheting mechanism using an electromagnetic coil. When the solenoid is activated, the core is pulled into the center and the disk rotates. A spring pushes it back to its starting position. The distance the ratcheting mechanism moves and the amount
  • How Robust is an LVDT
    All RDP transducers are housed in a robust stainless steel housing which provides both mechanical protection for the LVDT sensor as well as shielding the internal coils and electronics from external electromagnetic interference. The housing also serves to contain and concentrate the magnetic fields
  • Stepper Motor Theory
    motors incorporate a permanent magnet rotor, coil windings and magnetically conductive stators. Energizing a coil winding creates an electromagnetic field with a north and south pole as shown in figure 1. The stator carries the magnetic field which causes the rotor to align itself with the magnetic
