Product Description:
The 8LSA46.DA030S200-3 synchronous servo motor is manufactured by B&R Automation and belongs to the 8LS Synchronous Motors series. The internal designation 8LSA identifies a compact rotary drive designed for direct flange mounting. In an automation cell, the motor couples to a servo inverter and delivers commanded torque to belts, gears, or screw actuators while simultaneously reporting rotor position to the motion controller. This closed-loop operation supports coordinated multi-axis movement, speed regulation, and repeatable positioning in assembly, packaging, and material-handling equipment. The permanent-magnet rotor responds to inverter commands without the mechanical commutation components found in conventional brushed motors.
With a rated speed of 3000 rpm, the three-phase synchronous rotor reaches its nominal velocity without field weakening. Heat generated at that operating point is removed through self-cooling that relies on free air circulation, so no external blower or liquid cooling circuit is required. Power and feedback conductors exit the stator through a single-cable solution, reducing the number of connections routed through the machine. The mating interface uses a sealed connector that simplifies wiring inside moving cable tracks. Position feedback is provided by an inductive EnDat sensor, allowing the motion controller to monitor the rotor angle through a digital interface. The 100 mm square flange allows the housing to bolt directly to compatible machine frames while maintaining accurate shaft alignment.
The motor includes a standard holding brake that clamps the shaft when power is removed, preventing drift on vertical axes. The encoder provides 19 bits of single-turn resolution and 0 bits of multi-turn resolution, making the motor suitable for applications that index within one mechanical revolution. Communication follows EnDat version 2.2, which transmits digital position, phasing, and temperature data to the connected drive. Output torque passes through a smooth shaft without an oil seal, making the motor appropriate for clean environments where a shaft leakage barrier is unnecessary. A mounting flange supports direct installation, while the length code 6 indicates the stator stack configuration used by this model. The motor has standard bearings rather than a reinforced bearing assembly. This model is in its third revision and uses a single-turn encoder configuration.
