8MSA4M.E0-44

The 8MSA4M.E0-44 synchronous motor from B & R Automation embodies the robust engineering of the 8MS Three Phase Synchronous Motors series. This model features a Motor Size of 4M and delivers a continuous Rated Power of 4 kW at an operational Speed of 6000 rpm, making it well suited for medium-duty industrial applications. Engineered for precise motion control, it produces a stable Rated Torque of 8 Nm, ensuring reliable starting, stopping, and load-holding performance under varying conditions. Constructed to withstand harsh environments, it carries an IP65 Protection Class, which guarantees resistance to dust ingress and water spray. Built as part of the distinguished IndraDyn S Servo Motor Family, it provides a seamless extension to existing automation infrastructures.

Utilizing a Natural convection Cooling Method, the 8MSA4M.E0-44 dissipates heat effectively through its housing design, eliminating the need for auxiliary fans or liquid circuits. Its integrated Hiperface absolute encoder facilitates high-resolution feedback, enabling precise position and speed monitoring in closed-loop configurations. The motor operates on a standard Voltage Class of 400V, simplifying integration into common industrial power networks. Designed for high-duty cycles, its winding arrangement and case material enhance thermal stability and minimize thermal drift, contributing to longer maintenance intervals and reduced downtime. The combination of high-speed capability and encoder precision allows for responsive dynamic performance, even in demanding stop-and-go or cyclic motion profiles.

Operational features of this motor emphasize durability and ease of maintenance. The robust housing and sealing system support frequent exposure to industrial contaminants without compromising internal components. Its balanced rotor design minimizes vibration and acoustic noise, which is essential for assembly lines and robotic cells requiring smooth, predictable operation. The simple mounting footprint and flange dimensions allow direct replacement in existing installations or straightforward retrofit projects. With built-in overload tolerance and rapid thermal recovery, the motor sustains performance during transient loads and maintains consistent torque delivery.

Engineers will find the 8MSA4M.E0-44 straightforward to integrate with B & R Automation's drive controllers and control hardware. Its encoder interface supports standard Hiperface protocols, facilitating plug-and-play connectivity to motion control systems. The compact form factor, combined with proven industrial-grade protection, makes this motor ideal for applications such as conveyor systems, packaging machinery, printing lines, and pick-and-place robots. Whether deployed in high-volume production or precision assembly tasks, the 8MSA4M.E0-44 offers the reliability and performance needed to optimize automation processes.
