Brushless Motor We use a 100% pure copper coil brushless motor with a long life time, high efficiency, high speed, low interference, wide speed range, small size, light weight, and other advantages. The Strong Cooling Fan The strong cooling fan can quickly lower the surrounding temperature and has advantages such as high energy efficiency and quiet operation. The Independent Power Switch The independent power switch can quickly cut off the power when needed, providing excellent safety. It also offers convenience and ease of control management. Aluminum Alloy Brackets Aluminum alloy brackets are lightweight due to the low density of aluminum, making them easy to install and move. They also possess advantages such as corrosion resistance and high strength. The One-piece Die-cast Body The one-piece die-cast body utilizes an integrated casting process, which effectively enhances mechanical strength and rigidity, reducing the weaknesses that may arise from welded joints. It features less vibration and operates more quietly. The Belt Cover The belt cover can effectively prevent the belt and other moving parts from being exposed, reducing the risk of accidental contact and injury. It also helps to keep dust and dirt out, lowers noise levels, improves efficiency, and enhances aesthetic appeal. Easy to adjust speed & motor direction with buttons Adjustable belt tightener Belt guards, pulley & mounting hardware included Light weight Approx. 9 lbs. (4.2 kgs) Starts-up at low speed Works well on heavy duty machines Speed 0 - 4500 RPM 110 Volt, 3/4HP, 550 Watts, 50/60Hz Angular moment: ≤3N.M Application: This servo sewing machine motor is suitable for industrial sewing equipment such as flat sewing machines, synchronous carriages, double-needle machines, herringbone carriages, hemming machines, etc.
