WebFlexible magnetic field coils are available for testing vacuum interrupters while installed in switchgear and magnetic field coil test fixtures are available for testing when removed. Our unique, patented flexible magnetic field test coil enables vacuum bottle interrupters to be tested in-place, while installed in your circuit breaker or contactor. A field coil is an electromagnet used to generate a magnetic field in an electro-magnetic machine, typically a rotating electrical machine such as a motor or generator. It consists of a coil of wire through which a current flows. In a rotating machine, the field coils are wound on an iron magnetic core … See more Most DC field coils generate a constant, static field. Most three-phase AC field coils are used to generate a rotating field as part of an electric motor. Single-phase AC motors may follow either of these patterns: small motors are … See more Many rotary electrical machines require current to be conveyed to (or extracted from) a moving rotor, usually by means of sliding contacts: a commutator or slip rings. These contacts are often the most complex and least reliable part of such a machine, and may … See more • Excitation (magnetic) See more In the early years of generator development, the stator field went through an evolutionary improvement from a single bipolar field to a later multipole design. Bipolar generators … See more Coils are typically wound with enamelled copper wire, sometimes termed magnet wire. The winding material must have a low resistance, to … See more
