8MSA2M.R0-43
The 8MSA2M.R0-43 produced by B & R Automation is a high-performance member of the 8MS Three Phase Synchronous Motors series, designed to meet the rigorous demands of modern industrial automation. This compact motor delivers a maximum rotation speed of 3000 rpm while maintaining precise control thanks to its module 2 gearing arrangement and 43 number of teeth. Constructed from high-strength steel, the motor weighs just 0.97 kg, making it suitable for installations with strict mass constraints. Its helical tooth profile ensures smooth engagement and quiet operation, while the nitride surface treatment enhances durability by protecting against wear and corrosion. With a pitch diameter of 86 mm and a bore diameter of 20 mm, the 8MSA2M.R0-43 strikes the perfect balance between torque density and size.
Technically, the 8MSA2M.R0-43 excels with an Accuracy Class DIN 6, guaranteeing repeatable positioning accuracy in precision applications. The motor incorporates a standard backlash design and a keyway width of 6 mm to facilitate secure coupling and efficient power transfer under load. A face width of 15 mm contributes to compact integration without compromising structural stiffness. The interplay of its module, number of teeth, and pitch diameter parameters provides a harmonized gear ratio for consistent torque delivery across the entire speed range. At only 0.97 kg, the motor’s optimized inertia profile supports rapid acceleration and deceleration cycles, reducing settling times in high-dynamic systems.
Operationally, the 8MSA2M.R0-43 benefits from its helical tooth profile, which minimizes noise and vibration generation during meshing events, thereby extending component life and improving user safety. The nitride surface treatment further enhances operational reliability by resisting abrasion and chemical exposure in harsh environments. Lightweight yet rugged, the motor’s high-strength steel construction withstands shock loads and maintains alignment under continuous duty cycles. Its compact form factor, defined by the bore diameter, face width, and pitch diameter, simplifies mounting in applications where space is at a premium. With consistent performance at speeds up to 3000 rpm, this motor ensures smooth motion control for applications demanding precision and long-term stability.
Integration of the 8MSA2M.R0-43 into industrial systems is straightforward due to its standard keyway width of 6 mm and bore diameter of 20 mm, which align with common coupling interfaces. Its Accuracy Class DIN 6 rating makes it ideal for robotics, packaging lines, CNC machinery, and automated assembly systems. The combination of a compact face width and reduced mass allows seamless incorporation into multi-axis configurations, while the robust high-strength steel housing withstands challenging factory environments. Engineers will appreciate its balance of precision, reliability, and ease of installation in a wide range of industrial automation applications.
