Product Description:
The Three-Phase Motor 8MSA5S.E3-D300-1 has 3000 min⁻¹ rated speed, which ensures compatibility with high-speed applications requiring stable rotational output under dynamic loads. The B & R Automation has made this motor, and it’s rated at 4 A of current to provide efficient energy usage and consistent performance under normal load conditions.
This motor’s stator resistance of 4.15 Ω is directly equated with the same 4 A of rated current, ensuring that it provides stable thermal characteristics when operated continuously. The 8MSA5S.E3-D300-1 synchronous motor delivers a rated power output of 1.79 kW to make it suitable for various motion control tasks requiring dependable torque and speed balance. This motor’s stall current at 4.53 A ensures that it does not lose its torque-generating capacity during non-rotating load conditions and correlates directly with a stall torque of 6.6 Nm. In optimum performance, this synchronous motor provides a maximum current of 22.6 A. This current allows this motor to provide a peak torque of 19.8 Nm for its high efficiency in responding to short-term overloads and instant torque requests. This synchronous motor’s 1.46 Nm/A torque constant guarantees high accuracy torque output relative to current input, essential for applications where precise torque control is needed.
The electrical time constant of 6.7 ms also allows this motor to respond quickly to changing current, thus improving its dynamic performance during rapid switching. This synchronous motor's mechanical response is also complemented by a moment of inertia of 4 kgcm² without a brake. This figure allows it to maintain high acceleration profiles, complemented by a peak rotational acceleration of 49500 rad/s². For feedback control, the 8MSA5S.E3-D300-1 motor features an EnDat encoder system with 32 lines and 4096 revolutions for high-resolution position detection and synchronized system repeatability.
