Air gap between the stator and rotor core is smaller, therefore, our SG series generators have higher efficiency, compared with the products from other factories.
Excitation stator lamination is made by cold-rolled silicon steel sheet,with one or two high performance magnets, so the temperature rising of exciter is low, it will not lose excitation. Excitation start faster, easy to build pressure.Normally , when speed reach 600-700 rpm/min ,it is able to built pressure.
The biggest improvement is that, between driven disk and shaft,we adopts interference fit ,instead of key connection. Our advantage is that the process is more simple, the size is more precise,connection is more reliable.
Fujian Kwise Generator Co., Ltd. is wholly-owned by CASIC ADDSINO. It is a specialized generator manufacturer integrating R&D, production, sales and service. The company began to produce professional generators in 1955. From Fuzhou General Machinery Factory, Fuzhou Power Generation Equipment Factory, Fujian Fufa Co.,Ltd., to Fujian Kwise Generator Co., Ltd., we have a history of more than 60 years of generator producing , which is one of the earliest generators manufacturer in China.
Since 1964, our products have been provided into a large number of power generating equipments such as diesel generator sets, mobile power station, and containerized power stations. Also has been selected as the main power supply of China's three satellite launch bases, the Antarctic Zhongshan Station and the Shenzhou spacecraft series due to its superior performance. Kwise has more than 30,000 square meters of factory buildings and advanced manufacturing equipment.
