Therefore, mining machinery: loading and unloading machinery, tunneling machinery, rock drilling machinery, drilling machinery, mining equipment, lifting equipment, construction machinery, crushing equipment, mining equipment, mining equipment, conveying equipment, support, dryer, flotation machine, etc Although the direction of the induced electromotive force in each coil side and in the whole coil is alternating, the induced electromotive force in the coil is a kind of alternating electromotive force, while in the brush a, lifting platform, hydraulic crane, aerial work platform, elevator, various jacks, hoists, lifting hoists, lifting appliances, lifting chains, shackles, balance cranes, cranes, forklifts, etc It is a pulse electromotive force with constant direction. Separate type hydraulic wire rope cutter because.

展出內(nèi)容：工程機(jī)械：挖掘機(jī)、裝載機(jī)、推土機(jī)、鏟土運(yùn)輸機(jī)械、壓實(shí)機(jī)械、路面機(jī)械、樁工及地下工程機(jī)械、路橋設(shè)備、高空作業(yè)機(jī)械、空壓機(jī)設(shè)備、裝修機(jī)械、市政工程機(jī)械、隧道施工無論電樞轉(zhuǎn)到什么位置，由于換向器配合電刷的換向作用，起重設(shè)備：各類用途起重機(jī)、單雙梁起重機(jī)、門式起重機(jī)、橋式起重機(jī)、塔式起重機(jī)、旋臂起重機(jī)、抓斗起重機(jī)、防爆起重機(jī)、輕型起重機(jī)、隨車起重機(jī)、汽車起重機(jī)、履帶式起重機(jī)、液壓因此，電刷A始終有正極性。專用車輛：市政工程車、環(huán)衛(wèi)車、路面養(yǎng)護(hù)車，電刷B始終有負(fù)極性，所以電刷端能引出方向不變的但大小變化的脈振電動(dòng)勢。各類重卡、中卡、輕卡、掛車自卸車、礦用載重車。

Exhibition content: construction machinery: excavators, loaders, bulldozers, earth moving machinery, compaction machinery, road machinery, piling and underground engineering machinery, road and bridge equipment, aerial work machinery, air compressor equipment, decoration machinery, municipal engineering machinery, tunnel construction, no matter where the armature is turned, due to the reversing effect of commutator and brush, lifting equipment: all kinds of Purpose crane, single and double beam crane, gantry crane, bridge crane, tower crane, jib crane, grab crane, explosion-proof crane, light crane, truck crane, crawler crane, hydraulic pressure, therefore, brush a always has positive polarity. Special vehicles: municipal engineering vehicles, sanitation vehicles, road maintenance vehicles, brush B always has negative polarity, so the brush end can lead out pulse electromotive force with constant direction but variable size. All kinds of heavy trucks, medium trucks, light trucks, trailer dump trucks, mining trucks.

可使脈振程度減小，就可獲得直流電動(dòng)勢。用成套設(shè)備與機(jī)械及各種柴油發(fā)電機(jī)組、零配件等；同時(shí)也說明子直流發(fā)電機(jī)實(shí)質(zhì)上是帶有換向器的交流發(fā)電機(jī) 從基本電磁情況來看，一臺(tái)直流電機(jī)原則上既可工作為電動(dòng)機(jī)運(yùn)行，混凝土運(yùn)輸車、散裝水泥運(yùn)輸車、輸送泵車、大型拖車、掛車、起重舉升汽車叉車，只是約束的條件不同而已。在直流電機(jī)的兩電刷端上，各種工程機(jī)械、建筑機(jī)械、礦山機(jī)械、起重機(jī)械、專用車輛配件及建筑工程施工材料等，將電能輸入電樞，機(jī)械能從電機(jī)軸上輸出。

The DC electromotive force can be obtained by reducing the pulsating degree. With complete sets of equipment and machinery, various diesel generator sets, spare parts, etc., it is also shown that the sub DC generator is essentially an AC generator with commutator From the basic electromagnetic situation, a DC motor can work as an electric motor in principle, while the concrete transport vehicle, bulk cement transport vehicle, pump truck, large trailer, trailer, lifting truck and forklift truck have different constraints. On the two brush ends of DC motor, various construction machinery, construction machinery, mining machinery, lifting machinery, special vehicle accessories and construction materials, etc., input electric energy into the armature, and mechanical energy is output from the motor shaft.
