Product Description:

The B&R Automation 8LSN55.EB020D900-0 is a vibrant servo motor of the 8LS Synchronous Motors, which is created to keep up the requirements of superior-performance movement control.

The motor has a connected power of 6.1 kW, and an authorized voltage of 400 V. It has a maximum continuous torque of 30 Nm at a baseline speed of 2000 rpm, making it the perfect mid-range power unit for manufacturing processes where stability is needed. When running at full load, the motor has a torque of up to 64 Nm, and a corresponding peak current of 38.9 A, which makes it ideally suited for acceleration-intensive applications that require a great deal of dynamic response. It has a rated current of 13.2 A, thus applicable to a broad spectrum of industrial servo drives. It has a flange size of 130 mm, and the cooling is via natural convection, so that no extra fan and/or liquid cooling is necessary; this gives easy installation and low maintenance effort.

The motor has an absolute encoder that is required in terms of closed-loop control systems, where precision is not an option. The electrical terminals connect through a standard plug connector, easing the process of integration into the automation system. Because of its IP65 protection certification, the enclosure is dust-free and resistant to water jets, making it an excellent solution in a rigorous business setting. An additional 27 Nm of holding torque can be supplied by an optional 24 V DC permanent-magnet holding brake that secures a stalled load when the power is out. The rotor weighs about 0.45 kg-cm², which is relatively responsive but is stable enough to handle the load well.
