With Brother-developed direct drive motor and cutting-edge technology, S-7100A offers user-friendly operation and high-speed sewing without oil staining. The new hook enhances sewing capability for a wide range materials. -Comfortable and high-speed sewing -New hook enhances sewing capability -High reliable electrical equipment -Needle breakage prevention function -Environment-conscious Resolved oil staining with a minimum lubrication system to the needle bar: Minimum lubrication system is used for oil supply around the needle bar where it is said to occupy approximately over 90% of oil stain issues. It supplies the limited oil only to the needle bar and thread take-up and prevents oil from being dispersed, realizing clean sewing for your valued products. No oil necessary in the oil pan: Oil tank system has been adopted so it is not required to keep oil in the oil pan. The new hook enhances sewing capability: The new hook is improved the thread cast off enables to expand sewing range for medium materials. Achieved 5,000 sti/min with high reliability: The max. sewing speed achieved 5,000 sti/min, increasing the productivity. rother-developed direct drive motor and control box maximize the sewing performance while operating at the high speed. The machine can cont「ol box be used even areas where the power situation is unstable. Needle breakage prevention function: When reverse stitching is carried out with the actuator switch, needle breakage may occur. With thorough analysis of its cause, the function preventing the needle breakage has been introduced. Great needle penetration force: Powerful motor outputs large amounts of torque even at slow speeds so that strong needle penetration force can be obtained. If the needle penetration resistance increases, vibration control (intermittent impact) automatically increases the penetration force. Stable rotary-type thread trimmer: The rotary-type thread trimmer performs constant and stable thread trimming regardless of materials of threads with easy adjustment.
