{"product_id":"mdd025a-n-100-n2g-040fa1","title":"MDD025A-N-100-N2G-040FA1","description":"\u003cp\u003eThe \u003cstrong\u003eMDD025A-N-100-N2G-040FA1\u003c\/strong\u003e is a brushless synchronous servo unit built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it couples directly to compact axis modules to convert commanded current into precise rotary motion in automated assembly, packaging, and handling equipment. The motor follows size 025 geometry with a short A-length stator. It uses a standard housing, and its rotor is dynamically balanced to the standard grade so vibration remains low when integrated on lightweight mechanical frames. This operating role suits small servo axes that require fast and repeatable positioning during short motion cycles.\u003c\/p\u003e\u003cp\u003eIts performance envelope includes a continuous standstill torque of \u003cstrong\u003e0.33 Nm\u003c\/strong\u003e, allowing the drive to hold modest loads without exceeding thermal limits. Under rated excitation, the rotor can reach a nominal speed of \u003cstrong\u003e10000 rpm\u003c\/strong\u003e, supporting high throughput on small indexing tables. The flange uses a \u003cstrong\u003e40 mm\u003c\/strong\u003e centering diameter for accurate alignment to gearheads or adapter plates. This compact interface helps maintain accurate concentricity between the motor and the driven load. Power and feedback cables exit on \u003cstrong\u003eside A\u003c\/strong\u003e, and the motor uses a keyed \u003cstrong\u003econnector\u003c\/strong\u003e interface to simplify wiring. A shaft seal is not fitted, so the mounting location must remain free of splashing coolant or oil. The shaft end is provided on one side only.\u003c\/p\u003e\u003cp\u003ePosition retention during power-off states is handled by an integrated \u003cstrong\u003e1.0 Nm\u003c\/strong\u003e brake. The unit is supplied \u003cstrong\u003ewith a blocking brake\u003c\/strong\u003e, so vertical axes can remain parked without external clamps. Servo loop accuracy depends on embedded \u003cstrong\u003eresolver feedback\u003c\/strong\u003e, which supplies rotor angle information to the digital controller at high update rates. The resolver also supports commutation and stable speed regulation across changing load conditions. Drivetrain mating is straightforward because the rotor terminates in a \u003cstrong\u003eplain shaft\u003c\/strong\u003e, eliminating keyways that can introduce runout on miniature couplings.\u003c\/p\u003e","brand":"Bosch Rexroth Indramat","offers":[{"title":"Unstocked","offer_id":52038673269037,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/mdd025a-n-100-n2g-040fa1__899a18ba-23c6-48a1-99ee-edd7e6c33bdf.webp?v=1777966607","url":"https:\/\/servosupplier.com\/products\/mdd025a-n-100-n2g-040fa1","provider":"Servo Supplier","version":"1.0","type":"link"}
