Product Description:
The 8LSA46.R0030D000-0 synchronous motor is produced by B&R Automation as part of its 8LS Synchronous Motors series. This three-phase permanent-magnet unit delivers rotational motion to axes that require coordinated closed-loop control, such as pick-and-place gantries or packaging spindles. In industrial automation, it converts electrical power from a servo drive into precisely controlled mechanical torque. Its design also follows the standardized mounting and feedback conventions commonly used across B&R drive platforms, allowing it to integrate with compatible drive systems and machine assemblies.
The motor has a rated speed of 3000 rpm, providing the operating speed needed for many packaging, handling, and indexing applications. Its 100 mm flange provides a square mounting face that simplifies alignment on compatible machine plates. Position feedback is generated by a resolver, a magnetic transducer that supplies rotor-angle information to the servo drive for closed-loop control. Thermal management uses self-cooling with free air circulation, so the motor does not require an external blower or liquid-cooling jacket. Power and feedback leads exit through an angled swivel connection, which allows the cable direction to be adjusted for installations with limited routing space. The adjustable connection also helps reduce excessive bending and mechanical strain near the receptacle.
Mechanical repeatability is maintained within 10 arcmin, providing positional accuracy suitable for medium-precision indexing tables and similar automated equipment. The output interface uses a smooth shaft, allowing a clamping coupler or pulley to be attached without a keyway when low backlash is required. The motor has no holding brake, so static load retention must be provided by drive torque or an external clamping device when the axis is stopped. Field wiring is routed through a sealed connector, which protects the electrical contacts while allowing straightforward cable attachment. The motor has length code 6, indicating an extended magnetic stack within this frame. It is installed through its dedicated flange and does not include an oil seal, making it appropriate for clean, dry operating areas where the shaft is not exposed to lubricants or process fluids.
