Product Description:

The 8LSC86.E1020D000-3 is a three-phase synchronous motor manufactured by B & R Automation for the 8LS Synchronous Motors series. Within the 8LSC designation, this model uses the standard configuration without reinforced bearings, making it suitable for general-purpose axis control where external radial loads are moderate. The motor supplies regulated torque and speed so packaging lines, pick-and-place heads, and other servo-driven stations can maintain positional accuracy under dynamic duty cycles. Its synchronous design allows a compatible digital drive to regulate motion closely as operating loads and commanded speeds change.

The motor has a rated speed of 2000 rpm, allowing the shaft to track command profiles without approaching field-weakening limits. A 240 mm mounting flange aligns the housing with large gearboxes or direct-drive interfaces and provides a secure installation surface. Heat generated by copper losses is removed through a built-in fan assembly, which helps control winding temperature during sustained motion without separate external cooling equipment. An Optical EnDat encoder using EnDat 2.1 sends absolute position data to the drive for closed-loop commutation and motion control. The encoder provides a combined 13/12-bit resolution, supporting fine angular measurement during high-speed interpolation. This feedback allows the drive to monitor rotor position continuously and correct motion when the commanded profile or applied load changes.

Field wiring enters the stator through an angled connector that swivels to reduce cable stress and simplify routing inside articulated machines. The encoder supports a 4096-revolution multi-turn range, allowing the axis to retain absolute position across power cycles without an external battery. The motor has length code 6, which indicates the active stack depth selected for this torque class. The unit is produced as product revision 3 for accurate documentation and system records. A smooth shaft end transfers torque through a friction coupling, while the mounting flange supports rigid attachment to the driven equipment. The motor does not include a holding brake, so vertical or gravity-loaded axes require an external means of holding the load when power is removed. It also has no oil seal, which should be considered when the installation may expose the shaft interface to lubricants, coolant, or other fluid contaminants.
