ADVANTAGES:
- The DD AC motor is small and lighter, high power density ( to 10kw/kg), large output torque.
- Permanent Magnet rotor design achieving the highest efficiency -
values, wider torque/speed operating range
- Gearless, no gearbox to maintain due to direct driven fan, low noise, reduce losses, improves the transmission efficiency
- long service life, self-heat dissipation system; Truly maintenance-free
- More than 50 % energy saving
