8LSA75.D1030D200-3
The 8LSA75.D1030D200-3 is a three-phase synchronous motor produced by B&R Automation within the 8LS Synchronous Motors series. Designed for industrial positioning tasks, it provides precise torque and speed control to automated axes, conveyors, and process machinery. The unit uses the 8LSA configuration, which includes standard bearings without reinforcement, and it is furnished with a dedicated mounting flange for rigid attachment to a machine housing. Its smooth shaft simplifies coupling to gearboxes or pulley sets while helping reduce mechanical backlash during motion changes.
At the core of its performance profile is a rated speed of 3000 rpm, allowing the motor to track rapid command changes during normal operation. The mounting flange follows the DIN pattern with a diameter of 190 mm, which provides a broad face for secure bolting. Power and feedback leads exit through an angled swivel connector, reducing bend stress where installation space is limited. Position feedback is generated by an optical EnDat encoder that communicates through EnDat version 2.2 for digital resolution and stored motor data. Heat is removed by self-cooling with free air circulation, so no external blower or liquid jacket is required. This cooling arrangement keeps the motor layout compact and avoids the need for separate cooling hardware around the housing.
A standard holding brake is integrated to lock the shaft during power-off states, which helps prevent unwanted movement on vertical or suspended loads. The optical system provides 25/12 bits of single-turn and multi-turn resolution, and the encoder supports 4096 multi-turn revolutions before rollover for long travel ranges. The product is built in revision 3. This combination supports accurate position retention across extended axis travel while also providing a mechanical holding function when electrical power is removed.
