Product Description:

Bosch Rexroth Indramat manufactures the MDD090C-N-040-N2M-130GL2 as part of the MDD Synchronous Motors series. This motor for digital drive controllers converts drive output current into regulated rotary motion for positioning and speed-controlled tasks in industrial automation. The design combines a 090 frame size stator with a C-length rotor and incorporates an integrated multiturn absolute encoder to report shaft position to the controller. An internal blocking brake is included to hold the axis when power is removed, which is useful on vertical axes and other applications that require the load to remain in place.

The centering shoulder diameter is 130 mm, establishing the reference surface for precise flange mounting to gearboxes or machine frames. At standstill, the motor can deliver 10.4 Nm of continuous torque, which supports static holding or slow motion. Under rated excitation, it reaches a nominal speed of 4000 rpm, enabling direct coupling to moderate-speed spindles and conveyor rolls. Power and feedback cabling depart on the left side through a keyed connector, which can simplify routing where cabinet space is limited. The integrated holding brake sustains up to 11.0 Nm of static torque, and the length designation C indicates the active stack height used for this motor.

Position data are returned through digital servo feedback, allowing high-resolution velocity loops without external encoders. A molded shaft seal protects the internal bearings from coolant splash and helps keep contaminants away from the bearing area. The plain shaft geometry mates with compression couplings instead of keyed hubs, which suits installations that rely on friction-locking shaft connections. Standard dynamic balancing limits vibration at high speed, and the housing's standard cooling fins dissipate losses without forced air. The single-ended shaft arrangement omits a side-B extension to reduce overall length and simplify guarding.
