Product Description:
The 8LSA75.DB030S200-3 is a three-phase synchronous motor produced by B&R Automation for the 8LS Synchronous Motors series. The motor integrates into servo axes that require consistent torque and speed regulation in packaging lines, pick-and-place modules, and similar motion systems. Its standard bearings accommodate radial loads that remain within the normal limits for belt drives and couplings. The mounting flange allows the motor to be fastened directly to a driven assembly without additional alignment adapters. This arrangement supports compact installation where the motor must be positioned close to a gearbox, pulley, or machine frame.
A hybrid power-and-feedback connection uses a single-cable solution and terminates in a connector, reducing the number of separate cable runs. An inductive EnDat 2.2 encoder provides multiturn position capture and tolerates exposure to dust or condensation better than an optical sensing system. The sensor is positioned behind the stator stack, leaving the surrounding installation area clear. Thermal management relies on self-cooling with free air circulation, so the motor does not require a blower or liquid-cooling circuit. The mounting face uses a 190 mm square flange and includes a smooth shaft for press-fit or clamping couplings where a keyway is unnecessary. The motor maintains its rated mechanical output at speeds up to 3000 rpm, providing a balance of torque density and rotor inertia for rapid indexing. Its length code is 5, which indicates the active lamination stack depth.
A standard holding brake prevents vertical or unbalanced loads from drifting when the drive is disabled. The multiturn register covers 4096 revolutions, allowing the controller to retain turn-counting information across an extended range of motion. Feedback resolution is 19 single-turn bits and 12 multiturn bits, supporting precise position commands without losing the recorded revolution count. The shaft does not include an oil seal, so the installation must prevent lubricant from migrating along the shaft bore and entering the motor. Reinforced bearings are not installed, making the motor best suited to applications in which external side loads remain within the capacity of the standard bearing set. The smooth shaft and inductive feedback support repeatable positioning under normal belt or coupling forces. The motor is produced as Revision 3, which identifies its component and connection configuration.
