Product Description:
B & R Automation manufactures the 8LSA57.DB030S000-3, a three-phase synchronous motor in the 8LS Synchronous Motors series. The unit carries the 8LSA designation and product revision 3. It provides rotary actuation for positioning and velocity-controlled axes in industrial automation, using electromagnetic torque to drive connected loads.
The motor delivers a rated speed of 3000 rpm, allowing direct coupling to standard transmission ratios without exceeding its intended operating speed. A flange dimension of 142 mm provides the mounting interface, while length code 7 indicates the active stack depth inside the stator. Position feedback is supplied by a built-in inductive EnDat sensor that uses the open EnDat 2.2 protocol; this combination supports absolute position capture and automatic parameter transfer to the drive. Thermal management uses self-cooling with free air circulation, so no external fan or liquid cooling circuit is required. Power and feedback signals pass through a keyed connector, and the standard 8LSA configuration uses normal-duty bearings rather than reinforced bearings.
The motor uses a single-cable solution that carries motor current and encoder data through one hybrid cable, reducing the number of cabinet penetrations. Mechanical output is transferred through a smooth shaft, which accommodates clamping couplings and avoids the stress concentrations associated with a keyway. The encoder provides multi-turn capability across 4096 revolutions and has a 19/12-bit resolution for single-turn and multi-turn position data, respectively. The motor does not include a holding brake, so static load retention must be provided by drive-applied torque or an external clamping mechanism. It is also supplied without an oil seal, making it unsuitable for applications where the shaft interface is exposed to pressurized lubrication.
