The FVP series variable frequency speed regulation three-phase asynchronous motor is compatible with a frequency converter as the power supply, which can achieve stepless smooth speed regulation. Its frequency conversion range is 10Hz-80Hz, with constant torque operation within 10Hz-50Hz and constant power operation within 50Hz-80Hz. And this series of motors has high efficiency, smooth operation, and significant energy-saving effects. It is suitable for various printing and dyeing textile machinery such as cotton, wool, linen, silk, synthetic fibers, and other types of machinery. It can work in environments with dust, short fibers, and high temperature and humidity. Its structure is fully enclosed self fan cooled, with a protection level of IP44 and an insulation level of F.
