{"product_id":"mhd131b-024","title":"MHD131B-024","description":"\u003cp\u003eThe \u003cstrong\u003eMHD131B-024\u003c\/strong\u003e servo motor is produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is a permanent-magnet, electronically commutated unit intended for closed-loop drive systems that require accurate positioning and repeatable speed control. In automated cells, the motor couples to planetary gearboxes, timing belts, or direct-drive couplings so that programmable logic controllers can translate digital commands into precise rotary motion. The rotor and stator arrangement support smooth torque production across a wide operating range, which helps the axis respond predictably to changes in command speed and load. Shared mechanical dimensions within the MHD family support installation in standard mounting layouts used across the series.\u003c\/p\u003e\u003cp\u003eIts centering diameter is \u003cstrong\u003e250 mm\u003c\/strong\u003e, creating a broad pilot surface that aligns the stator housing concentrically with adjoining machinery. A continuous standstill torque of \u003cstrong\u003e48.0 Nm\u003c\/strong\u003e allows the shaft to support static loads for extended periods without exceeding permissible winding temperature. The rectangular flange follows a \u003cstrong\u003e260 mm\u003c\/strong\u003e bolt circle, enabling direct attachment to standard reducer or spindle faces. Length code \u003cstrong\u003eB\u003c\/strong\u003e extends the magnetic core to increase copper fill and iron path, which adds thermal mass for sustained operation. Frame size \u003cstrong\u003e131\u003c\/strong\u003e corresponds to the stator diameter used for this motor size and matches the mechanical envelope used in the series.\u003c\/p\u003e\u003cp\u003eWinding code \u003cstrong\u003e024\u003c\/strong\u003e corresponds to a turns-per-phase ratio suited to intermediate DC-bus voltages and moderate base speeds. As a \u003cstrong\u003eservo motor\u003c\/strong\u003e, the unit uses encoder feedback for real-time control, allowing the drive to generate sinusoidal current profiles without additional sensors. The machined shoulder serves as the \u003cstrong\u003ecentering interface\u003c\/strong\u003e, while the square bolt circle provides the \u003cstrong\u003eflange pattern\u003c\/strong\u003e; these features help maintain coaxial alignment between the rotor, bearings, and coupled load during rapid acceleration and deceleration. Stable alignment also helps reduce coupling runout and uneven bearing loading during repeated reversing motion.\u003c\/p\u003e","brand":"Bosch Rexroth Indramat","offers":[{"title":"Unstocked","offer_id":52038696239405,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/mhd131b-024__640f2c1b-10a6-4283-9ad8-afea23f88ee5.webp?v=1777967281","url":"https:\/\/servosupplier.com\/products\/mhd131b-024","provider":"Servo Supplier","version":"1.0","type":"link"}
