Product Features

The device applies the specially designed AC220V special torque motor, which is a kind of low speed and maintenance-free motor, and can be braked at any position without any damage to itself. When at the two end limit positions, the power of the motor will be reduced automatically to around 10-15W, which can both save energy and avoid condensation and corrosion, enabling its normal working even in cold winter. Sine bar system is applied for its transmission mechanism, eliminating the deceleration device applied by normal auto bar system, enabling a more compact and reasonable system, greatly reducing the mechanical failure. Its motor coil structure avoids instant high-current and instant voltage fluctuations which is inevitably needed for normal motors. It can be powered by UPS directly, without impacting the normal working of other equipment within the same power grid. Appearance of the structure is both durable and beautiful, the frame is made of special process treated steel plate, with its surface being color zinc plated, presenting excellent anti-corrosion performance.
