Product Description:

The 8MSA2L.E5-I6 is a three-phase synchronous motor produced by B&R Automation for the 8MS Three Phase Synchronous Motors series. Designed as a compact drive element, the unit converts current from a servo inverter into mechanical rotation for machine tools, packaging stations, and other automated axes that require continuous precision. Its modular design provides mechanical dimensions and feedback options that are consistent with related motor frames. This arrangement supports straightforward integration into coordinated motion systems while maintaining accurate torque, speed, and position control. The motor is suitable for applications that require responsive acceleration and repeatable movement within a compact machine layout.

The motor reaches a nominal speed of 6000 rpm, giving short-cycle machines a high velocity ceiling while maintaining high rated torque relative to its size. Thermal management relies on self-cooling, so airflow over the housing removes heat without an external blower. Power and feedback connectors exit on the B-side, and the motor uses frame size 2 with length code L, which sets the stack depth and flange pattern. Because the unit is supplied without a holding brake, an external device must secure the shaft when drive torque is unavailable. The motor also lacks an oil seal, so the shaft area should be protected from lubricant and other contaminants. For position sensing, the integral incremental disc provides 512 lines. Its analog bandwidth supports encoder frequencies of at least 200 kHz (-3 dB), and its angular precision is ±60 arcseconds, allowing tight velocity control at full speed.

The higher-level controller reads rotor position through an EnDat interface that carries position data and power through the feedback connection. The installed multi-turn encoder recognizes up to 4,096 revolutions, retaining absolute position after power loss and eliminating the need for a homing move. During installation, the shaft can withstand up to 200 N of axial force without damaging the bearings. Torque is transmitted through a smooth shaft that supports coupling to precision collets or friction hubs. The plain shaft surface allows a clamping coupling to establish concentric contact without relying on a keyway. Installers should keep the applied axial load within the stated limit when fitting or removing the coupling. Correct alignment helps prevent unnecessary bearing stress and supports stable position feedback during rapid acceleration and deceleration.
