Product Description:
The 8LSA57.E1045D000-0 synchronous motor is produced by B & R Automation and belongs to the 8LS Synchronous Motors series. It is a three-phase synchronous unit intended to convert electrical power into controlled rotary motion for positioning, conveying, or spindle tasks in industrial automation. The model follows the 8LSA configuration without reinforced bearings, and it relies on an external drive to supply current and process encoder feedback. This arrangement allows the drive to regulate motor torque, speed, and position according to commands from the machine controller.
Its rated shaft speed reaches 4500 rpm, allowing fast cycle times when the motor is paired with suitable gear ratios. Thermal management uses self-cooling through free air circulation; air moves over the housing without auxiliary fans, so the motor can be installed where space is limited. Heat dissipates directly through the stator housing during continuous operation. Position feedback is provided by an optical EnDat encoder that offers a resolution of 13/12 bits for single-turn and multi-turn position data, supporting fine interpolation in servo loops. A flange dimension of 142 mm provides the interface between the motor and the machine frame and matches IEC size requirements for mid-frame actuators.
The power and feedback leads exit through an angled swivel cable entry coupled to a keyed connector, simplifying cable routing in tight enclosures. An integrated mounting flange supports installation, while length code 7 indicates the overall body depth associated with that interface. Multi-turn capacity of up to 4096 revolutions retains absolute position information through power cycles with EnDat 2.1 communication. The standard bearing arrangement accommodates moderate radial forces commonly produced by belt-driven assemblies. The motor is supplied without a holding brake or oil seal and has a smooth shaft, so an external clamping device is necessary when the load must remain stationary without motor power. A suitable external seal is also required when the shaft interface needs additional protection from oil or contaminants.
