Product Description:
The 8MSA3S.R0-31 is a product of B & R Automation, which is a three-phase synchronous motor with an output shaft diameter of 15 mm to be adaptable with a broad variety of couplings and transmission systems.
With an electrical response time of 1.17 milliseconds, the 8MSA3S.R0-31 motor facilitates high-frequency control updates and real-time system adjustment with little delay. Its winding resistance of 75 Ω helps in accurate current regulation and heat control for increased long-term operational reliability. For electrical installation, this motor requires a suggested wire size of 1.5 mm² that allows a safe and reliable current supply over long distances. This 8MSA3S.R0-31 synchronous motor is constructed to meet IEC 60034-14 vibration requirements, Grade R in particular, to ensure performance stability against mechanical stress and vibration exposure. With its maximum rotational acceleration of 66667 rad/s², this motor shines in applications with very high rates of speed change and direction change. The 0.99 Nm/A torque per amp rating offers this motor high torque output at lower currents, with greater efficiency and less thermal burden on drive electronics.
This motor’s 2.8 A maximum current handling supports short-term high-demand torque without endangering component life. This synchronous motor has a continuous power contribution of 0.19kw that usually helps in effective working under long duration without any overload in terms of thermal or electrical. In the 8MSA3S.R0-31 synchronous motor, a resolver encoder system is used, giving strong, noise-immune feedback in conditions where accuracy and electromagnetic immunity are required. This three-phase synchronous motor supports a nominal torque of 0.6 Nm to give a smooth torque during normal loads, and its locked torque of 0.65 Nm means that it is able to start in full heavy mechanical load.
