Product Description:
A compact, very precise synchronous servo motor, the B&R Automation 8LSN43.DB030S300-1 is a member of the 8LS family of motors.
This motor is designed to carry the highest load in the tightest space of a harsh automation application, with a 43 mm high shaft, and 030 coded motor length, providing the right profile suited to where the system must be space-efficient. It is provided with a square 115mm flange, making it simple to mix with conventional mountings. The motor can achieve speeds of 6000 rpm, whereas continuous torque is rated at 3.0 Nm, making it highly powerful with a high torque density and dynamism as well. It is designed with a rated current of 3.3 A in a 400 V voltage class, thus fitting in most service applications in industry using servo drives. The cooling is done in a passive manner by using natural convection, thereby not needing any external fans and making it very easily mounted in small enclosures. The motor includes a DB-type encoder, an 18-bit single-turn absolute encoder, hence giving accurate feedback to achieve high precision in positioning and motion control.
Such a resolution is a perfect match to the use of the system in pick-and-place machines, robotics, and automated machinery, among others, where accuracy is paramount. The holding brake is not incorporated in the unit, so this can be used in systems where the stopping torque is externally covered or where the stopping torque is unnecessary. For consistent industrial usage, it is built to IP65 water and dustproof strength, which completely ensures protection against dust particles and low-pressure streams. It can operate in harsh conditions because of its Thermal class of F (winding temperature up to 155°C). A rotating socket is used for the connection, which makes wire routing easier during installation and adds flexibility even in small spaces.
Frequently Asked Questions about 8LSN43.DB030S300-1:
Q: What type of encoder does the 8LSN43.DB030S300-1 motor include?
