The surface hardness is optimized for wear resistance, and the steel material construction ensures mechanical robustness. The resolver system achieves a precision of \u003cstrong\u003e±10 angular minutes\u003c\/strong\u003e and a non-linearity of \u003cstrong\u003e±1 angular minute\u003c\/strong\u003e, securing stable position feedback in critical applications. Rated for a maximum speed of \u003cstrong\u003e12 000 rpm\u003c\/strong\u003e and a peak torque of \u003cstrong\u003e21.2 Nm\u003c\/strong\u003e, it supports high-speed system dynamics. A thermal time constant of \u003cstrong\u003e64 minutes\u003c\/strong\u003e guarantees predictable thermal behavior during extended operation. The motor’s weight without brake is \u003cstrong\u003e5.6 kg\u003c\/strong\u003e, with a no-brake moment of inertia of \u003cstrong\u003e2.65 kg·cm²\u003c\/strong\u003e. Recommended cable cross-section is \u003cstrong\u003e1.5 mm²\u003c\/strong\u003e for consistent electrical connectivity.\u003c\/p\u003e\n\n\u003cp\u003eOperationally, the 8MSA4M.R0-44 produces a levelling torque of \u003cstrong\u003e5.3 Nm\u003c\/strong\u003e and achieves a maximum rotational acceleration of \u003cstrong\u003e80 000 rad\/s²\u003c\/strong\u003e, enabling swift start-stop cycles. Its robust helical tooth design minimizes acoustic noise and vibration, improving system quietness and longevity. The integrated resolver eliminates homing routines, reducing downtime and enhancing throughput. Self-cooling airflow is maintained through a built-in fan and optimized internal channels, ensuring thermal stability in varying ambient conditions. Optional holding brake integration adds a holding torque of \u003cstrong\u003e8 Nm\u003c\/strong\u003e when power is removed, securing the load during standstill.\u003c\/p\u003e\n\n\u003cp\u003eSystem integration is streamlined by standardized mounting holes and a common mounting pattern, facilitating drop-in replacement in existing equipment. Compatibility with B \u0026amp; R Automation motion controllers enables advanced features such as synchronous tracking, camming, and electronic gearing. Ideal for robotics, packaging machinery, CNC indexing tables, and automated assembly lines, the 8MSA4M.R0-44 excels in applications where precise positioning, high dynamic response, and industrial-grade reliability are imperative.\u003c\/p\u003e","brand":"B \u0026 R Automation","offers":[{"title":"Unstocked","offer_id":52108218990893,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/8MS_Three_Phase_Synchronous_Motor_Series__c149eef0-0a00-488f-ab52-71e1333ae105.webp?v=1757360147","url":"https:\/\/servosupplier.com\/products\/8msa4mr0-44","provider":"Servo Supplier","version":"1.0","type":"link"}
