Internal Product Review
The 8MSC5L.R0-X200-2 is a B & R Automation three-phase synchronous motor with separate cooling. Large relative rated torque and a BRX resolver make the motor especially well suited for controlled servo duty. Resolver non-linearity of ±1 angular minute stands out as a strong precision advantage.

Product Description:
The 8MSC5L.R0-X200-2 is a three-phase synchronous servo motor manufactured by B&R Automation and supplied within the 8MS Three Phase Synchronous Motors series. Designed for direct coupling to high-performance inverters, the motor converts electrical input into precisely controlled shaft torque for positioning and speed-regulation tasks in automated machinery. Its permanent-magnet rotor and stator windings provide the dynamic response needed in packaging, pick-and-place, and material-handling systems. An integrated feedback interface supplies the connected drive with the rotor information required for closed-loop control throughout each operating cycle.
The stator is kept at its operating temperature by a separate cooling circuit, so cabinet airflow does not have to carry the motor’s thermal load. A frame code of 5 indicates the outer diameter and flange pattern used for mounting on medium-torque axis modules. The L length designation indicates an extended active magnetic stack that increases continuous power density. This configuration provides a high relative rated torque, allowing the shaft to transmit greater steady-state torque than smaller configurations in the same product range. Position and velocity feedback are provided through a resolver, which generates analog sine-cosine signals for the drive. These signals allow the inverter to monitor shaft movement and correct differences between the commanded and measured motion.
The motor uses the BRX feedback variant, which is selected for mechanical durability and resistance to elevated operating temperatures. Its nonlinearity is limited to ±1 angular minute, keeping the difference between the electrical angle and mechanical position minimal during one electrical cycle. Across the complete 360-degree range, its precision remains within ±10 angular minutes, supporting accurate closed-loop control during low-speed operation. The common connector orientation supports orderly cable routing when several motors are installed on neighboring machine axes. A consistent pinout helps prevent wiring conflicts between the motor feedback interface and compatible drive equipment. The protective earth arrangement also provides a dedicated grounding path for the motor housing and connected cable assembly.
