SRH door operator SGAD superiority

The SGAD permanent magnet variable frequency door operator is driven by the latest magnetic-synchro motor and controlled by the latest step-less speed regulation and frequency-variation door controller, through which the door opening and closing speed curve can be adjusted. The operation, energy-saving, high efficient, reliable and easy, can greatly satisfy modern people’s demands of high efficiency, energy conservation and convenient operation. The compact mechanical structure, applicable to a variety of installation ways, can be widely used in residential buildings, business buildings, hotels and other locations with different requirements.

·Compact structure: it uses the most advanced flat rare-earth permanent magnet synchronous motor drive system; besides, the compact mechanical structure can greatly save the space. There is no height limit for the elevator car, and the hoistway utilization rate is high.

·Accurate control: it adopts the latest step-less speed regulation and frequency-variation controlled gate driver to realize close-loop vector control and real-time speed feedback; the speed control accuracy can reach 0.1%.

·Energy-efficient: it uses the latest magnetic-synchro motor and the latest step-less speed regulation and frequency-variation controlled gate drive system; the economy energy rate is high up to above 60%.

·Good adaptation: Wide operating voltage range.

·Other functionalities: Unique fault memorizing and protection; Adjustment for door knife opening and closing speed curve; Synchronous and asynchronous choice for door knife; Slow door closing once power off; Protection for encoder failure; Force torque check for clamping etc.
