Product Description:

The 8LSA75.DA030S500-3 is a three-phase synchronous servo motor from B&R Automation in the 8LS Synchronous Motors series. It converts controlled current from a servo amplifier into torque and speed for positioning axes used in conveyors, gantries, and assembly stations. The motor uses the 8LSA configuration, which has a standard housing without reinforced bearings. It is equipped with a heavy-duty holding brake to hold vertical or suspended loads when power is removed.

The motor reaches a rated mechanical speed of 3000 rpm, making it suitable for servo applications that require a high operating speed. A flange dimension of 190 mm sets the mounting size and supports direct attachment to compatible machine faces. Cooling is handled by self-cooling with free air circulation, so no forced ventilation ducts are required around the housing. Power, feedback, and brake conductors are combined in a single-cable hybrid connection, which reduces cable routing complexity. Rotor position and speed are monitored by an Inductive EnDat feedback system, and the shaft uses a key for positive torque transmission to the driven load.

The feedback interface uses EnDat 2.2 for bidirectional data exchange between the motor and the drive. Internal interpolation provides a resolution of 19/0 bits for the available single-turn and multi-turn ranges. The motor is built with length code 5, which gives it a medium body size for this platform. Product revision 3 is used on this version of the motor. The design does not include an oil seal, so the coupling area should be protected from lubricant entry. Mechanical attachment is made through the flange, the standard bearing arrangement is intended for normal radial loads, and the connection hardware uses a locked circular connector to maintain signal stability during vibration.
