Product Description:
The 8LSA57.DB030S200-3 is a three-phase synchronous motor from B&R Automation that belongs to the 8LS Synchronous Motors series. The 8LSA designation identifies the motor configuration, while product revision 3 indicates its release level. It uses the standard build without reinforced bearings. The unit converts drive-inverter output into rotary motion for conveyors, pick-and-place modules, and single-axis gantries where accurate electronic commutation is preferred over mechanical speed control.
The motor relies on self-cooling through free air circulation, so no external fan or liquid cooling circuit is required. Power and position signals share a single-cable hybrid connection that terminates at a rugged connector, reducing the number of cable entry points. Position is measured with an inductive EnDat 2.2 sensor, which supplies digital multi-turn data and supports automatic calibration. A flange dimension of 142 mm provides a broad mounting interface for compatible machine assemblies. Length code 7 indicates the motor’s axial housing configuration and associated mounting dimensions. The rotor can operate continuously at a rated speed of 3000 rpm, enabling direct coupling to moderate-inertia loads. Because the motor does not have an oil seal, the shaft should remain inside a dry housing to reduce the risk of lubricant migration or contaminant entry.
Operational security is provided by a standard holding brake that locks the rotor when the drive releases the brake command, preventing vertical or overhung loads from drifting. Controller accuracy benefits from a feedback resolution of 19/12 bits, allowing fine single-turn interpolation while reporting absolute revolution counts. The concentric coupling face uses a smooth shaft, which accommodates collets or clamping hubs and avoids the stress concentration associated with a keyway. Long-term absolute position tracking is maintained through a multi-turn range of 4096 revolutions, allowing the machine to retain the correct coordinates after a power loss without performing a homing sequence. The hybrid connection consolidates motor power, brake control, and encoder communication within one cable assembly, which reduces separate wiring runs between the motor and drive. The inductive feedback system is suitable for industrial motion axes that require repeatable position data during frequent starts, stops, and direction changes.
