In China's construction machinery mainly include: mining machinery, earth moving machinery, construction cranes, road machinery, compaction machinery, piling machinery, concrete machinery, drilling machines, forklifts, construction machinery and other special 10 categories. Its classification similar to other countries, such as the United States said the construction machinery for construction machinery, construction machinery, Weifang East Japan called diesel supplier, Russia is called the building and road construction machinery. Specifically common engineering machinery: hydraulic excavators, crawler dozers, wheel loaders, rollers, graders, pavers, forklift and automobile cranes. Engineering machinery generator stator principle, also known as the armature. Stator function is to generate alternating current. When the exciting current acting on the rotor windings Weifang Huadong Diesel manufacturers, Weifang Huadong rotor shaft diesel engine manufacturers in the timing gear drive, the induced electromotive force in the stator winding. Folded by the stator core inner grooved silicon steel wires of the stator winding is embedded into the core slots. Three-phase stator winding, three-phase windings are connected in star or delta connection, can produce a three-phase alternating current. Three-phase windings must be according to certain requirements around the system, to make it get the same frequency, amplitude equal to 120 ° phase difference between each phase electromotive force. Weifang Huadong Diesel wholesale | Weifang Huadong (certified) | Weifang Huadong provided by Weifang Diesel Engine Co., East China. Weifang Huadong Engine Co., Ltd. (www.hdchai.com) is an industry leader in Shandong Weifang, the internal combustion engine, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
