8MSA5M.R0-Y1
The B & R Automation 8MSA5M.R0-Y1 is a compact yet powerful flange-mounted synchronous motor in the 8MS Three Phase Synchronous Motors series. Engineered by B & R Automation, this unit delivers a rated output power of 300 W and supports a rated current of 2.1 A for efficient light-to-medium duty automation tasks. Its robust design features an integrated high-resolution 23 bit absolute encoder and a peak torque of 2.8 Nm to ensure precise positioning under dynamic load changes. The motor is protected to IP65_degree_of_protection against dust ingress and water jets, making it suitable for challenging industrial environments.
The 8MSA5M.R0-Y1 offers a range of critical specifications for precise motion control. It operates at a rated voltage of 200 V and produces a rated torque of 0.95 Nm at a rated speed of 3000 rpm. Maximum rotational capacity reaches 6000 rpm, enabling high-speed applications. The rotor’s low inertia of 0.15 kgcm² promotes rapid acceleration and deceleration profiles. With a thermal class of 155 (F), this motor withstands elevated temperatures while maintaining performance. The unit’s overall mass is Approx. 1.9 kg, and its flange mounting interface simplifies mechanical integration.
Operational reliability is enhanced by the motor’s Self-cooling (natural air) mechanism, eliminating the need for external fans or liquid cooling systems. It maintains stable thermal conditions across an ambient operating temperature of 0 °C to +40 °C, while sustaining continuous performance at the specified load. The synchronous rotor design ensures consistent torque delivery and minimal speed variation under fluctuating loads. Its high-precision encoder feedback enables closed-loop control systems to achieve sub-millimeter positioning accuracy. The IP65 protection rating guarantees resilience against corrosive factory floors and washdown procedures.
System integration is streamlined through standardized flange mounting and a compact form factor that fits space-constrained equipment. The 8MSA5M.R0-Y1 pairs seamlessly with B & R Automation control drives and PLCs for unified industrial automation solutions. Ideal applications include pick-and-place machines, small-scale robotics, conveyor systems, and precision assembly lines. This motor’s blend of performance, protection, and feedback precision makes it a versatile component in modern manufacturing installations.
