Product Description:

The 8LSA46.E3030D300-0 motor is produced by B&R Automation and is part of the 8LS Synchronous Motors series. Designed for integration into industrial drive systems, it supplies controlled rotary power to machinery that depends on coordinated multi-axis motion. The 8LSA designation within the series indicates a standard mechanical layout that allows the motor to pair with flange-mounted gear stages, ball screws, or direct-coupled loads in automated work cells.

This unit follows a three-phase synchronous topology, allowing the stator windings to connect directly to inverter outputs that deliver balanced phase currents. Its rated speed is 3000 rpm, which is the continuous shaft velocity at nominal torque. Heat is removed by a self-cooling system that relies on free air circulation, so no external blower or liquid loop is required. Mechanical coupling uses a 100 mm flange, a dimension that aligns with common ISO mounting patterns. Position retention during power-off is provided by the factory-installed standard holding brake, eliminating the need for an external brake on vertical or static-load axes. The length-code 6 housing provides additional axial length for torque capacity without requiring forced cooling.

Electrical and feedback leads exit through an angled connection area that can swivel, helping maintain gentle cable bends in tight enclosures. Quick disconnect of those leads is handled by the integrated connector interface, which supports straightforward cable attachment and removal. The shaft uses a keyed shaft end so pulleys or couplings can lock to a standard keyway. Because the design includes no oil seal, the motor is better suited to clean, dry environments where lubricants or process fluids are not directed at the shaft. The standard configuration also omits reinforced bearings and remains suitable for moderate radial loads when alignment at the flange is maintained.
