Product Description:
The 8LSE85.E1020D000-3 is a three-phase synchronous servo motor manufactured by B&R Automation within the 8LS Synchronous Motors series. The model carries the internal 8LSE designation and is intended for high-precision rotary axes in automated machinery. When paired with a compatible AC drive, the motor converts controlled stator current into repeatable torque and speed. This operation allows packaging, robotics, and material-handling systems to position loads accurately within compact mechanical envelopes. Electronic commutation also supports responsive acceleration and controlled rotation across demanding motion cycles.
The motor is supplied in the standard configuration and attaches to machinery through a mounting flange measuring 240 mm across. Heat is removed through a liquid-cooled A-side flange, allowing continuous operation under high loads while helping maintain a stable winding temperature. A sealed connector has an angled, swiveling orientation, which simplifies cable routing around nearby machine components. The housing has length code 5, providing an extended stator stack for elevated continuous torque without increasing the frame diameter. The motor reaches a nominal output speed of 2000 rpm, making it suitable for midrange motion tasks on conveyors, gantries, and press equipment. The rotor follows the commanded drive frequency directly during synchronous operation. The motor does not include a holding brake, so an external mechanism or drive-applied torque is required when a stationary load must be retained. It is also supplied without an oil seal, reducing shaft drag in clean operating areas. The motor is product revision 3.
Position feedback is provided by an Optical EnDat version 2.1 encoder, which sends digital position information to the connected drive. The measuring system provides 13-bit single-turn resolution for precise angular feedback within each mechanical revolution. It also offers an absolute multi-turn range of 4096 revolutions without requiring battery backup. This capability preserves the tracked shaft position across multiple turns and allows the controller to recover the absolute axis location after power is restored. Feedback wiring and motor power connections are arranged at the same housing interface, reducing the number of separate cable-routing points. The smooth shaft end supports direct installation with suitable clamping couplings for gearboxes or timing pulleys. Because the shaft has no keyway, the selected coupling must provide sufficient clamping force to transmit the required torque without slipping.
