Product Description:

The B&R Automation 8LSN56.EB030D300-0 is a highly accurate synchronous servo motor of the 8LS product range, which is designed to handle the most challenging motion control applications.

With a length code of E and a frame size of 56, this motor is compact and produces a lot of power. It has a flange with a 115 mm diameter, and a 19 mm shaft, which makes it suitable for numerous coupling systems. The total motor length can usually vary between 220 to 250 mm with variations based on feedback and options. This motor's rated capacity is 1.34 kW, and its average speed is 3000 rpm. It is perfect for low- to mid-range mechanical applications where a steady torque is required since it produces an output torque of 4.3 Nm. In high-load applications, it can provide stall torques of approximately 20 Nm, making it appeal to applications involving either large inertia or sustained position holding against load. The measurement system has an absolute encoder (marked EB030D300-0), which allows the proper tracking of the position without re-homing following power down.

It works in four pairs, and its pole and the entire series of 8LS 56 frame motors have the advantage of smooth movement and accurate control of motion. Natural convection serves as the cooling mechanism, making the engine silent and effective without the need for an additional fan. Operating securely in challenging situations is made possible by the IP65 protection level, which guarantees total immunity to dust infiltration and low-pressure water jets. It is also constructed mechanically robust, peak radial shaft load is about 600 N at 20 mm to the flange, and is suitable for belts, pulleys, or gear assemblies.
