{"product_id":"mdd071b-n-040-n2m-095pb1","title":"MDD071B-N-040-N2M-095PB1","description":"\u003cp\u003eThe \u003cstrong\u003eMDD071B-N-040-N2M-095PB1\u003c\/strong\u003e is a permanent-magnet synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it translates commanded current into repeatable shaft rotation in assembly robots, indexing tables, and material-handling axes. This operating role suits compact automation equipment where repeatable positioning is required through frequent cycle changes. The model combines a standard housing with internal balancing, so it can be mounted in compact machine frames without additional vibration dampers. A factory-installed blocking brake prevents drift when power is removed, which supports vertical or suspended loads during routine stops.\u003c\/p\u003e\u003cp\u003eThe mechanical interface uses a centering diameter of \u003cstrong\u003e95 mm\u003c\/strong\u003e, which allows precise pilot seating against gearbox or flange surfaces. Power and feedback cabling exit on \u003cstrong\u003eSide B\u003c\/strong\u003e, and the circular \u003cstrong\u003eConnector\u003c\/strong\u003e system keeps the connection compact in cramped cabinets. At standstill, the motor delivers a continuous torque of \u003cstrong\u003e4.4 Nm\u003c\/strong\u003e, supplying steady holding force for indexing operations. When driven by a matched inverter, it can reach a nominal speed of \u003cstrong\u003e4000 rpm\u003c\/strong\u003e, which suits mid-range linear velocities on belt or ball-screw stages. Standard housing and shaft sealing protect the internal windings from ambient dust or coolant mist, while the length code B and 071 frame size keep overall mass low for high dynamic response.\u003c\/p\u003e\u003cp\u003ePosition accuracy is maintained by an \u003cstrong\u003eintegrated multi-turn absolute encoder\u003c\/strong\u003e that returns shaft angle data over the drive’s \u003cstrong\u003edigital servo feedback (DSF)\u003c\/strong\u003e channel, eliminating the need for external reference switches after power cycles. That feedback path also lets the control loop monitor axis motion during acceleration, dwell, and braking. During a commanded stop, the blocking brake supplies \u003cstrong\u003e3.0 Nm\u003c\/strong\u003e of torque to secure the axis, allowing the electronic amplifier to be disabled without mechanical creep. The ground shaft has a \u003cstrong\u003ekeyway\u003c\/strong\u003e for positive coupling to pulleys or couplings, and its single-ended design leaves the rear free for the side-B connector arrangement.\u003c\/p\u003e","brand":"Bosch Rexroth Indramat","offers":[{"title":"Unused Surplus","offer_id":52056677777709,"sku":null,"price":10842.58,"currency_code":"USD","in_stock":true},{"title":"Refurbished","offer_id":52056677810477,"sku":null,"price":2652.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/mdd071b-n-040-n2m-095pb1__cc077942-aba6-4fec-9479-882f7a461017.webp?v=1778571149","url":"https:\/\/servosupplier.com\/products\/mdd071b-n-040-n2m-095pb1","provider":"Servo Supplier","version":"1.0","type":"link"}
