Product Description:
The 8LSA45.E2030D100-0 synchronous motor is produced by B&R Automation for the 8LS Synchronous Motors series. It carries the 8LSA designation, which indicates a standard build without reinforced bearings. As a three-phase electromechanical actuator, the device supplies regulated torque and speed to motion axes in automated assembly, packaging, or conveying equipment, enabling precise positioning under servo drive control. Its length code 5 stator stack offers a balance between continuous output and installation depth, making the unit suitable for machinery with limited mounting space.
Electromagnetic performance comes from a three-phase synchronous winding topology working with a permanent-magnet rotor. Under nominal conditions, the shaft reaches 3000 rpm, a speed class that aligns with common servo gear ratios and high-throughput indexing cycles. Thermal energy is removed through self-cooling with free air circulation, so no auxiliary blower or liquid cooling loop is required. The motor has a 100 mm square flange that simplifies alignment with gearboxes or machine frames, while precision pilot fits provide axial retention. The motor is supplied without a holding brake, so an external clamp or drive-controlled torque must secure vertical loads while power is off. A single connector houses the power and feedback pins, reducing the number of separate cable connections required at the motor.
An angled swivel connection routes the connector away from the housing in a low-stress arc, reducing cable bend fatigue on moving carriages. Drive torque exits through a cylindrical shaft machined with a key to provide positive engagement with couplings or pulleys. The integral mounting flange secures the motor directly to the machine without separate foot brackets. The enclosure is built without an oil seal, so the surrounding installation must protect the shaft opening from lubricant splashes and coolant ingress. Direct connector access also allows the cable to be routed without sharp turns near the motor housing. The keyed shaft supports couplings that require positive mechanical engagement rather than relying entirely on clamping force. The flange arrangement keeps the motor centered during installation and helps maintain alignment between the shaft and the connected load.
