8LSA35.DB030S200-3 by B & R Automation

The 8LSA35.DB030S200-3 is a three-phase synchronous motor manufactured by B & R Automation and assigned to the 8LS Synchronous Motors series. In industrial automation, it provides electrically driven rotary motion for axes that require closed-loop speed and position control. The unit follows the 8LSA standard configuration without a reinforced bearing and incorporates a smooth shaft so couplings or pulleys can be fitted directly. These characteristics make the motor suitable for compact packaging, material-handling, and assembly equipment where direct drive and consistent servo performance are required.

The motor reaches a rated speed of 3000 rpm, giving a balance between throughput and servo accuracy for general-purpose machinery. Power, feedback, and brake lines are routed through a hybrid single-cable solution, and a molded connector at the housing completes the electrical interface. Position feedback is generated by an Inductive EnDat encoder that operates with EnDat version 2.2 for bidirectional parameter communication. The mechanical interface uses a flange that measures 91.3 mm across, and the stator stack corresponds to length code 5 to limit overall depth. A standard holding brake supplies static torque during emergency stops while keeping installation width unchanged.

Heat is removed by self-cooling through free air circulation, so no external fan or liquid loop is required. The encoder delivers an absolute resolution of 19/12 bits for single-turn and multi-turn operation and tracks up to 4096 revs of rotation, so the axis retains position data after power cycling. Quick fastening is provided by the integrated mounting flange, and because an oil seal is not present, the motor should be placed in clean environments or fitted with external covers. The motor is product revision 3.
