{"product_id":"r911253813","title":"R911253813","description":"\u003cspan\u003eThe Bosch Rexroth R911253813 (MDD090B-N-020-N2L-110PB1) is a digital servo motor with a frame size of 090 and frame length identified as 'B'. The motor comes with a standard housing and offers two cooling methods, surface cooling and natural convection. With surface cooling, airflow across the motor housing is increased, which allows for greater heat dissipation, enabling the motor to provide greater output current and torque. Specifically, with natural convection the continuous torque at standstill is 7.2 Nm, whilst with surface cooling it's 10.5 Nm. Similarly, the continuous current at standstill is 8.3 Amps for natural convection, but 12.2 Amps for surface cooling. The rated speed for this servo motor is 2000 RPM. \n\nThe R911253813 (MDD090B-N-020-N2L-110PB1) utilises digital servo feedback, with an integral encoder measuring the motor's speed and torque. These readings are fed back to a controller that makes necessary adjustments to keep motor parameters aligned with programmed values. The motor comes with a shaft with a keyway to prevent any relative rotation between the shaft and the connected machine. It also includes a 6.5 Nm rated blocking brake to avoid unintentional shaft movement. The power connection for this motor is situated on side B, and it's essential that only trained professionals handle and operate this servo motor.\n\u003c\/span\u003e","brand":"Bosch Rexroth Indramat","offers":[{"title":"Unused Surplus","offer_id":52061603070253,"sku":null,"price":7532.46,"currency_code":"USD","in_stock":true},{"title":"Refurbished","offer_id":52095030395181,"sku":null,"price":4536.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/mdd090b-n-020-n2l-110pb1__2cf9de8c-e65b-4563-97ac-ed38caeb790c.webp?v=1779175048","url":"https:\/\/servosupplier.com\/products\/r911253813","provider":"Servo Supplier","version":"1.0","type":"link"}
