FZWL70/35-4 type brushless DC motor for textile is a brushless DC motor used for automatic winding machine slot drum. The power supply is 220V AC 50Hz, the speed control signal is 0-10V DC, the motor speed range is 1:70 (100-7000r/min), and the normal operation is 5000 r/min. It can operate in both forward and reverse directions, with a reverse speed of less than 100 r/min. It has the advantages of high reliability, simple structure, easy maintenance, good characteristics (fast response speed, good low-speed performance), easy heat dissipation, speed not limited by mechanical commutation, long service life, and low noise. Suitable for various textile, printing and dyeing machinery such as cotton, wool, linen, silk, and chemical fibers. It can work in environments with high dust, short fibers, and high temperature and humidity, and can also be used to drive other mechanical equipment.
