8LSA56.S0045D200-1 by B & R Automation

The 8LSA56.S0045D200-1 motor is manufactured by B&R Automation within the 8LS Synchronous Motors series. Carrying the internal designation 8LSA, it is the standard build without a reinforced bearing. The unit is intended for positioning and speed-controlled tasks in automated lines where compact rotary power must work with an inverter and a high-resolution feedback device. Its layout suits servo axes that need accurate motion in a compact installation space.

It operates as a three-phase synchronous machine, permitting sinusoidal current control and precise torque production. The rated mechanical speed reaches 4500 rpm, so the rotor can follow rapid command sequences without exceeding typical industrial gear-stage limits. The motor has a flange dimension of 142 mm, which aligns it concentrically with gearboxes or load couplings. Thermal energy is removed by self-cooling with free circulation, eliminating the need for external blowers at nominal load. Position data come from an optical EnDat encoder that communicates through EnDat version 2.2 and provides digital feedback for closed-loop control. A standard holding brake is integrated to secure the load during power-off events, and length code 6 indicates the housing depth used for the required electromagnetic volume. Because no oil seal is fitted, the application must avoid fluid ingress at the shaft interface.

Electrical and feedback terminals are arranged on an angled swivel-style connector block, allowing the cable exit to be oriented during installation. Power, brake, and encoder conductors share a single industrial connector, which reduces the number of separate cable interfaces. The motor is secured through a mounting flange, and its smooth shaft simplifies coupling while minimizing fretting. The encoder provides 25/0 bits of single-turn and multi-turn resolution, and the feedback format is single-turn. That arrangement keeps the connection area compact when the motor is mounted close to adjacent machine parts.
