Product Description:
The 8LSA73.E1022D200-0 is a three-phase synchronous motor manufactured by B & R Automation for the 8LS Synchronous Motors series. Supplied in the 8LSA configuration without reinforced bearings, this model delivers controlled rotary motion for indexing tables, gantry axes, and other positioning tasks in automated machinery. A mounting flange aligns the frame with compatible housings, while the smooth shaft end allows direct coupling to gearboxes or belt drives. Its internal encoder transmits absolute position data to the drive controller, allowing the connected servo amplifier to regulate position and speed. The synchronous design supports repeatable movement when the motor is paired with an appropriate drive and control system.
The motor’s maximum continuous shaft speed is 2200 rpm, establishing its speed limit at the rated load. A flange dimension of 190 mm establishes the face size and bolt circle used when securing the unit to a machine frame. Feedback is generated by an optical EnDat sensor, and its communication conforms to EnDat 2.1, enabling high-speed, bidirectional data exchange with compatible servo amplifiers. A standard holding brake supports load holding during a power loss or emergency stop. The brake clamps the rotor through spring force until the control voltage releases it, helping prevent unintended shaft movement. This arrangement is suitable for axes that must remain stationary when drive power is unavailable.
Fine feedback granularity is provided by a 13/12-bit single-turn and multi-turn resolution pair, allowing tight velocity loops and precise homing routines. The encoder supports 4,096 revolutions of multi-turn tracking without losing absolute position, eliminating the need for reference moves after shutdowns. Thermal management relies on self-cooling with free air circulation, so heat dissipates through the housing without an external fan or liquid circuit. Power and feedback conductors exit through an angled swivel connection that mates with a keyed circular connector, easing cable routing where installation space is limited. The motor uses length code 3 for its stator stack. It does not have an oil seal, which reduces shaft friction in applications that do not require additional sealing at the output.
