Product Description:
The 8LSA45.E0022D200-0 is supplied by B & R Automation within the 8LS Synchronous Motors series. It is intended for installation on machine frames in automated production lines. In these applications, the motor delivers precise rotary motion to gearboxes, ball screws, or direct-drive stages that require controlled positioning and speed.
This unit employs self-cooling with free air circulation, so heat is removed without forced ventilation. During continuous operation, it can reach a rated speed of 2200 rpm, providing a suitable operating range for regulated motion. Position feedback is generated by an optical EnDat encoder that uses protocol revision 2.1. The encoder provides 13 bits of single-turn resolution and no multi-turn resolution, allowing the controller to monitor the shaft position within one mechanical revolution. A flange dimension of 100 mm matches common IEC size patterns and supports accurate alignment with compatible machine interfaces. The integrated standard holding brake clamps the shaft when power is removed, helping prevent load drift on vertical or suspended axes.
The motor uses a three-phase synchronous design, allowing its stator windings to operate with field-oriented control from a compatible inverter. Installation is supported by a mounting flange that provides a rigid connection to the machine frame. A smooth shaft transfers torque through a clamping coupling or another suitable friction-based connection without requiring a keyway. The length code 5 indicates the selected rotor stack depth, which provides the torque and inertia characteristics associated with this motor configuration. Power and feedback conductors pass through a single connector housing mounted on an angled swivel, allowing the cable direction to be adjusted for the available installation space. The motor is supplied in its standard 8LSA form without reinforced bearings. No oil seal is installed at the shaft, so applications that require liquid containment must use a suitable external sealing arrangement.
