The FTYP series textile three-phase permanent magnet synchronous motor is a fully enclosed self fan cooled three-phase permanent magnet synchronous motor developed using rare earth materials. It has high speed regulation accuracy, wide speed regulation range, small size, light weight, easy control, and high reliability. Adopting open-loop control improves the reliability and reduces the price of the entire variable frequency control system. The energy-saving effect is obvious. Compared with ordinary asynchronous motors, it has high efficiency and a power factor of over 0.95.
