2. Permanent magnet motor - Wikipedia

   en.wikipedia.org/wiki/Permanent_magnet_motor

   Permanent magnet motors consist of two main types. Surface permanent magnet motors (SPM) and internal permanent magnet (IPM) motors. The main difference is that SPM motors place the magnets on the outside of the rotor while IPM motors place their magnets inside the motor. Benefits to internal magnets include structural integrity and reducing ...

3. Electropermanent magnet - Wikipedia

   en.wikipedia.org/wiki/Electropermanent_magnet

   An electropermanent magnet or EPM is a type of permanent magnet in which the external magnetic field can be switched on or off by a pulse of electric current in a wire winding around part of the magnet. The magnet consists of two sections, one of "hard" (high coercivity) magnetic material and one of "soft" (low coercivity) material. The ...

   A MIL-DTL-38999 circular connector plated with a nickel–teflon composite. Left: plug (male) type connector; Right: receptacle (female) type connector) Electrical or fiber-optic connectors used by U.S. Department of Defense were originally developed in the 1930s for severe aeronautical and tactical service applications, and the Type "AN" series set the standard for modern military circular ...

5. Beamline - Wikipedia

   en.wikipedia.org/wiki/Beamline

   It is imperative to have all beamline sections, magnets, etc., aligned (often by a survey and an alignment crew by using a laser tracker), beamlines must be within micrometre tolerance. Good alignment helps to prevent beam loss, and beam from colliding with the pipe walls, which creates secondary emissions and/or radiation.

6. Sextupole magnet - Wikipedia

   en.wikipedia.org/wiki/Sextupole_magnet

   A sextupole magnet (also known as a hexapole magnet) consist of six magnetic poles set out in an arrangement of alternating north and south poles arranged around an axis. [1] They are used in particle accelerators [ 1 ] for the control of chromatic aberrations and for damping the head—tail transverse plasma instability .

8. Permanent magnet synchronous generator - Wikipedia

   en.wikipedia.org/wiki/Permanent_magnet...

   A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is induced into the stationary armature.

9. Quadrupole magnet - Wikipedia

   en.wikipedia.org/wiki/Quadrupole_magnet

   Quadrupole magnets are useful as they create a magnetic field whose magnitude grows rapidly with the radial distance from its longitudinal axis. This is used in particle beam focusing. The simplest magnetic quadrupole is two identical bar magnets parallel to each other such that the north pole of one is next to the south of the other and vice ...
