Product Description:
The 8LSA57.D0030D000-3 synchronous motor is manufactured by B&R Automation within the 8LS Synchronous Motors series. It is a three-phase actuator intended to drive machine axes that require repeatable positioning and consistent speed. The 8LSA designation indicates a standard build without a reinforced bearing, providing a compact package for installations that do not impose high radial loads. Delivered as product revision 3, the motor works with compatible servo drives that regulate torque, acceleration, and stopping accuracy in modular automation systems.
The motor reaches a rated speed of 3000 rpm, allowing direct coupling to gear stages or load shafts without exceeding the speed limits of typical industrial machinery. Heat is removed through self-cooling by free air circulation, eliminating the need for external blowers or liquid cooling circuits. Power and feedback cables exit through an angled swivel connector, which simplifies cable routing where installation space is limited. The front face has a 142 mm square flange that provides a broad mounting surface for stable alignment. The housing supports flange mounting, allowing the motor to be secured directly to a compatible machine frame with four bolts.
Position feedback is provided by an optical EnDat encoder that uses protocol version 2.2. The single-turn sensor supplies position data at a resolution of 25/0 bits, supporting precise electronic commutation and accurate axis control. A smooth shaft transmits torque without a keyway and accommodates a suitable clamping coupling for dynamic operation. The lack of a keyway also allows the coupling to be positioned without aligning a key during installation. The motor is supplied without a holding brake, so an external holding device is required when a stationary load must remain secured after power is removed. It also has no oil seal, making additional protection appropriate where lubricant, coolant, or other contaminants could reach the shaft opening. Length code 7 indicates the active stack height, while the swivel connector permits access to the cable connection without changing the motor’s installed alignment.
