Product Description:

B&R Automation 8LSA55.R0030D300-0 is a synchronous servomotor that belongs to the series 8LS, used in high precision applications.

This motor has a stated torque of 3.0 Nm, and a frame dimension of 55. The unit's top speed of 6000 rpm makes it suitable for use in robotics, automation systems, and other applications that need precise motion control and high speeds to guarantee seamless operation. It is rated as having 1.26 kW of output power and operates on a 400 V AC supply. It is a 4-pole pair motor with a base speed of 3000 rpm, at a supply frequency of 50 Hz. It offers a high stall torque of 12.5 Nm to enable high, static holding power and would be ideally suited in applications where start-stop cycles are frequent or where the loads vary. Feedback is controlled via a digital encoder network, where there are resolver/encoder options depending upon the layout. Since it is naturally cooled by convection, it requires less external fan cooling and is easier to integrate into the design of compact machines. The motor has a hybrid connector that is used for combined power and signal. This simplifies cabling, and it simplifies the installation process.

This device is ideal for severe business settings since it is flange-mounted and has an IP65 rating, which guarantees total protection against dust and resistance to water jets. There is an optional 15 Nm holding brake, which is internally constructed to hold the shaft in position when power has been lost, which increases safety in a vertical axis or load-sensitive system. It has been calibrated to respond effectively to acceleration without compromising stability, and its rotor inertia value is 0.00145 kg m². The motor weighs around 5.8 kg and varies depending on the brake and connection.
