8LSA44.S1022C200-0 by B & R Automation

The 8LSA44.S1022C200-0 synchronous motor is manufactured by B&R Automation and belongs to the 8LS Synchronous Motors series. It is a three-phase device intended for closed-loop motion axes where precise position, velocity, and torque are required. When paired with compatible AC drives, the unit provides repeatable rotary motion for automated pick-and-place heads, feed rollers, and servo-controlled tooling stations.

Thermal management is handled by a self-cooling with free circulation design, so no external blower or liquid circuit is needed under rated load. Position feedback is generated by an optical EnDat encoder that communicates through the EnDat version 2.2 protocol, allowing absolute position transfer and electronic nameplate data. Mechanical attachment uses a flange that measures 100 mm across, providing a standard interface to gearboxes or machine frames. A standard holding brake is integrated to keep the shaft locked whenever the drive is disabled, which helps on vertical or load-bearing axes. Under continuous operation, the rotor can reach a rated speed of 2200 rpm, allowing direct coupling to moderate-speed production equipment without secondary gearing.

Cabling exits the housing in a straight top connector orientation, which can simplify routing when cabinets are located below the motor. The optical encoder supplies single-turn and multi-turn data with a resolution of 25/12 bits, supporting fine incremental moves while also tracking revolutions. Multi-turn capability extends to 4096 revs, so homing after power-up is unnecessary in most applications. The motor also has a smooth shaft end for friction-fit couplings. It is supplied without an oil seal for use in protected enclosures, and the length code is 4. The standard 8LSA configuration does not use reinforced bearings when radial loading remains within normal limits.
