31Resolver (electrical) — A resolver is a type of rotary electrical transformer used for measuring degrees of rotation. It is considered an analog device, and has a digital counterpart, the rotary (or pulse) encoder.DescriptionThe most common type of resolver is the… …
32Brushless DC electric motor — A microprocessor controlled BLDC motor powering a micro remote controlled airplane. This external rotor motor weighs 5 grams, consumes approximately 11 watts (15 millihorsepower) and produces thrust of more than twice the weight of the plane …
33Field coil — A field coil is a component of an electro magnetic machine, typically a rotating electrical machine such as a motor or generator. A current carrying coil is used to generate a magnetic field. Magnetic fields require a continuous circuit, thus… …
34Distribution transformer — Single phase distribution transformer in Canada A distribution transformer is a transformer that provides the final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the… …
35Commutator (electric) — This article is about the electrical component. For mathematical concept, see Commutator . A tiny 5 segment commutator less than 2 mm in diameter, on a direct current motor in a toy radio control ZipZaps car. A commutator is a rotary electri …
36Argument principle — In complex analysis, the Argument principle (or Cauchy s argument principle) states that if f ( z ) is a meromorphic function inside and on some closed contour C , with f having no zeros or poles on C , then the following formula holds: oint {C}… …
37Gramme machine — A Gramme machine or Gramme magneto. A Gramme machine, Gramme ring, Gramme magneto, or Gramme dynamo is an electrical generator which produces direct current, named for its Belgian inventor, Zénobe Gramme, and was built as either a dynamo or a… …
38geomagnetic field — Magnetic field associated with the Earth. It is essentially dipolar (i.e., it has two poles, the northern and southern magnetic poles) on the Earth s surface. Away from the surface, the field becomes distorted. Most geomagnetists explain the… …
39magnetism — /mag ni tiz euhm/, n. 1. the properties of attraction possessed by magnets; the molecular properties common to magnets. 2. the agency producing magnetic phenomena. 3. the science dealing with magnetic phenomena. 4. strong attractive power or… …
40Brushed DC electric motor — A brushed DC motor is an internally commutated electric motor designed to be run from a direct current power source. Contents 1 Simple two pole DC motor 2 The commutating plane 2.1 Compensation for stator field distortion …
