Product Description:

The MDD090B-N-020-N2M-110GL1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. This motor is intended for direct coupling to digital drive controllers where it delivers controlled torque and position in industrial automation. It includes integrated feedback and an internal blocking brake for load holding when the axis is disabled. Typical duties include coordinated motion on material-handling gantries, rotary tables, or ancillary axes that require repeatable positioning accuracy.

At standstill, the motor supplies a continuous torque of 7.2 Nm, allowing sustained load support without thermal overload. Its nominal mechanical speed is 2000 rpm, matching machines that run at moderate yet precise cycle rates. The integrated brake provides 6.5 Nm of static holding torque, preventing back-driving on vertical or indexing axes once power is removed. Position feedback comes from the integrated multiturn absolute encoder, while velocity loops are closed using digital servo feedback (DSF) signals to the controller. Power, signal, and brake conductors exit through a left-side connector orientation, which can simplify wiring when motors are mounted in mirrored pairs. Standard dynamic balancing minimizes vibration during operation.

Mechanical integration is aided by a centering diameter of 110 mm, which aligns the flange precisely on gearheads or machine plates. The rotor transmits torque through a plain shaft that accepts couplings without keyways, and an oil-retaining shaft seal guards against lubricant migration. The housing uses the standard cooling configuration, and motor size 090 keeps the envelope compact for confined spaces. With the B length code, the motor reaches its rated torque without extending overall width, while the absence of a side B shaft end simplifies installation against bulkheads. A keyed circular connector carries power, brake, and feedback lines in a single plug.
