5. The brief introduction of wide application of this model
1) Textile industry: Decrease fault and improve productivity;
special textile frequency function while is suitable for winding
devices. Reasonable construction design which is easy to clean.
2) Injection machine: fast response. big torque to make better
molding. Energy saving rate reaches up to 25%-70%. Independent dust
design and easy ti take apart for cleaning and maintenance.
3) Machine tool industry: high frequency output; main stream open
loop control: excellent PWM adjusting method, to keep noise within
a lower range at high-speed working condition. Big torque for
cutting in low frequency, shorter deceleration and acceleration and
packing industry.
