{"product_id":"mhd041b-144","title":"MHD041B-144","description":"\u003cp\u003eThe \u003cstrong\u003eMHD041B-144\u003c\/strong\u003e is an AC synchronous drive unit produced by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. Intended for industrial automation, the unit translates drive current into controllable rotation so that pick-and-place axes, indexing tables, and compact milling heads maintain commanded speed and position profiles during repetitive production cycles. Its \u003cstrong\u003epermanent-magnet rotor\u003c\/strong\u003e, digital feedback interface, and stator winding profile let the associated drive amplifier generate finely metered torque across a broad speed range while supporting repeatable motion in packaging lines, electronics assembly cells, and material-handling gantries.\u003c\/p\u003e\u003cp\u003eA machined pilot with a centering diameter of \u003cstrong\u003e50 mm\u003c\/strong\u003e aligns the housing concentrically inside gearboxes or brackets, and a square face that follows an \u003cstrong\u003e82 mm\u003c\/strong\u003e flange pattern provides four tapped holes for rigid attachment at the machine face. When energized continuously, the stator develops \u003cstrong\u003e2.7 Nm\u003c\/strong\u003e at standstill, allowing the axis to resist static loads while the feedback loop remains closed at zero speed. Winding code \u003cstrong\u003e144\u003c\/strong\u003e sets the electrical characteristics used by the drive, and stack length \u003cstrong\u003eB\u003c\/strong\u003e increases rotor depth so higher torque is achieved without enlarging the front face.\u003c\/p\u003e\u003cp\u003eWith frame classification \u003cstrong\u003e041\u003c\/strong\u003e, the motor offers a favorable ratio of inertia to mass, making it suitable for lightweight robots that still need smooth acceleration and stable speed control during short index moves. The precision-ground \u003cstrong\u003eflange\u003c\/strong\u003e and concentric pilot support accurate mounting of couplings or gear stages without shimming, which helps preserve shaft alignment at the machine interface. The unit is classified as a \u003cstrong\u003eServo Motor\u003c\/strong\u003e, which reflects its use in closed-loop motion systems that require controlled speed, repeatable positioning, and smooth torque delivery during frequent start-stop cycles.\u003c\/p\u003e","brand":"Bosch Rexroth Indramat","offers":[{"title":"Unused Surplus","offer_id":52056185045293,"sku":null,"price":5495.62,"currency_code":"USD","in_stock":true},{"title":"Refurbished","offer_id":52056185078061,"sku":null,"price":4996.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/mhd041b-144__a81e958b-1b25-46fc-8884-f6f4f262684e.webp?v=1777967211","url":"https:\/\/servosupplier.com\/products\/mhd041b-144","provider":"Servo Supplier","version":"1.0","type":"link"}
