  • Permanent Magnets and Electromagnets - Different Magnet Types Feature Different Properties
    Magnets work in hundreds of applications around you daily. Depending on the use, the magnet could be a permanent magnet or an electromagnet. Permanent magnets and electromagnets both possess different characteristics and benefits.
  • Exploring Permanent Magnet Motors
    As its name would suggest, a permanent magnet motor contains a permanent magnet that is composed of a material that can be magnetized. In a permanent magnet motor, the magnetic field of the rotor or stator is produced by this permanent magnet, generating a constant motor flux; this is unlike
  • Magnets Speed up Production
    Permanent and electro-magnets play a crucial role in many automated and semi-automated manufacturing plants.
  • Dexter Helps Companies Go Green!
    A rare permanent magnet system can replace a high power consumption electromagnet in the beam bending or deflection section a mass spectrometer.
  • State-of-the-Art Technology to Obliterate Boundaries in Science and Medicine
    Two examples will be introduced to demonstrate the permanent magnet technology and its feasibility in the medical and scientific applications, where in general electromagnets have been used
  • 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
  • Brushed DC Motor Fundamentals
    , and how a drive circuit can be interfaced to a PIC (R) microcontroller. The stator generates a stationary magnetic field that surrounds the rotor. This field is generated by either permanent magnets or electromagnetic windings. The different types of BDC motors are distinguished by the construction
  • EC Motors: Principle of Operation
    Electric motors run by electromagnetism. However, there are also other types of motors that utilize electrostatic forces or piezoelectric effect. In the case of a PMDC (Permanent Magnet DC) motor, motion is produced by an electromagnet (armature) interacting with a fixed field magnet (housing
