Product Description:
The 8LSA57.DB030S400-3 is a three-phase synchronous motor produced by B&R Automation for the 8LS Synchronous Motors series. Supplied in the 8LSA configuration, it has no reinforced bearing and mounts to a machine frame through an integral flange. The unit delivers precise rotary motion for automated axes that require position feedback and consistent torque. Its synchronous design supports controlled positioning, indexing, and speed regulation in industrial automation equipment.
This motor reaches a rated speed of 3000 rpm, allowing it to drive packaging spindles or transfer belts at standard production rates. Thermal energy is dissipated through self-cooling with free air circulation, so no external fan is required. The mounting interface has a flange size of 142 mm, providing a stable connection to a compatible machine frame. A heavy-duty holding brake is integrated to keep vertical or indexing loads stationary whenever motor power is removed. Rotor position is measured with an inductive EnDat encoder, and version 2.2 of the protocol supports digital diagnostics and automatic parameter transfer. The encoder head provides single-turn and multi-turn feedback without batteries, while the smooth shaft end connects to gearboxes or pulleys through a suitable clamping coupling. Internal wiring exits through a detachable connector, and length code 7 indicates the stator stack depth associated with the motor’s continuous torque capability. The housing is sealed against dust, but the shaft does not have an oil seal for operation in areas exposed to fluids.
Power, feedback signals, and the brake supply share a single-cable hybrid connection, reducing machine wiring and eliminating the need for a separate feedback cable. The encoder supplies a 19/12-bit resolution, providing detailed position data within each revolution and absolute tracking across a 4,096-revolution multi-turn span. This feedback arrangement allows the connected drive to retain absolute position information across multiple shaft rotations without relying on a battery. The motor incorporates revision 3 hardware updates while retaining its established mounting dimensions, connector arrangement, and cooling clearances. These fixed interfaces help maintain consistent mechanical alignment and cable routing within compatible installations.
