FS12A-4 and FS12-4 textile three-phase asynchronous motors are fully enclosed self cooled squirrel cage low-power motors for textile use. The base and end caps are made of aluminum alloy die-casting, suitable for various textile machinery such as cotton, wool, linen, silk, and chemical fibers. They can work in environments with high dust, short fibers, and high temperature and humidity, and can also be used to drive other machinery.
