8LSA65.EB045D200-1 by B & R Automation

B&R Automation manufactures the 8LSA65.EB045D200-1 as a member of the 8LS Synchronous Motors series. The product is a three-phase synchronous motor intended for precise position and speed control in automated production lines, packaging stations, and handling modules. Its 8LSA construction uses a standard bearing arrangement rather than a reinforced bearing set, and the unit mounts through an integral flange so it can be seated directly on machine frames. This layout supports compact installation on equipment that requires accurate rotary motion without a separate motor base.

The motor reaches a rated speed of 4500 rpm, allowing rapid cycle times while remaining within the thermal limits of length code 5. A flange dimension of 190 mm aligns with common gearbox and frame interfaces, simplifying mechanical integration. Rotor position is monitored by an Inductive EnDat encoder that transmits digital feedback in EnDat version 2.1. Single-turn and multi-turn resolution is 19/12 bits, providing fine angular granularity for interpolation in the drive controller. The smooth shaft end reduces stress concentrations and suits couplings that clamp directly to the shaft.

Thermal management relies on a self-cooling principle with free air circulation, eliminating the need for auxiliary fans or liquid circuits. Power and feedback conductors exit through an angled swivel connector, enabling cable routing in tight cabinets while reducing cable strain at the connection point. A standard holding brake secures the load during power loss or emergency stop events. Because the encoder supports multi-turn counting, the rotor position remains valid across up to 4096 revs without battery backup. The design excludes an oil seal, so the motor is intended for clean, enclosed environments where low friction is preferred.
