Three-phase stator windings connected in a star connection, there are two characteristics of the line current is equal to the phase current, and the three phases are connected together at one end. The instantaneous value of the neutral point voltage is a third harmonic voltage, the average value of the neutral point voltage is half the generator output voltage (average), the generator can be used with a neutral point terminal voltage to control the neutral point various uses relays. 1) The effective distance between the edges of two for each coil should be and the space occupied by a distance equal to the magnetic pole. (2) adjacent coils of each phase winding starting edge distance and distance between a pair of magnetic poles should occupy equal or multiples. (3) the beginning of the three-phase windings should be spaced side 2π + 120o electrical angle (a pair of pole space occupied by an electrical angle of 360o). Cover and brush assembly cover generally divided into two parts (drive end cap and brush cover) Construction Machinery engine manufacturers, from the support of the rotor, stator, rectifier and brush assembly role. Cover with aluminum casting general construction machinery engine price, one can effectively prevent the leakage flux, the second is good aluminum alloy heat dissipation. Brush assembly mounted on the brush cover. Brush assemblies without the regulator by the brush, the brush holder and the brush springs, brush assembly with regulator by the brush, brush holder, brush springs and adjuster components. The role of the brush is the power to introduce the field winding through the slip ring. Two brushes were installed in the hole of the brush holder engineering machinery engines, with the spring pressure to maintain contact with the slip ring. Contact brushes and slip rings should be good, or because the field current is too small, resulting in insufficient power generators.
