Functional features:
1. With adoption of gear mechanical transmission systems, the machine is featured with high efficiency and low noise.
2. With braking function, the spindle is flexible and reliable.
3. With adoption of frequency control in electrical system, the machine controls braking using a frequency converter, so start and brake slopes can be preset for optimal winding.
4. The scope of frequency control is wide. Sped regulation is accurate and stable. The insulation level of the motor is level F.
5. Automatic winding displacement, auto-displacement inter layer trapezoid insulation.
