Product Description:
The MDD090B-N-040-N2L-110GL2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for axis drives in automated machinery where accurate torque and speed regulation are required. By coupling with a compatible digital drive controller, the unit converts commanded current into mechanical rotation so that positioning systems, packaging equipment, or machine-tool spindles can follow programmed motion profiles without mechanical gearing. The motor is suited for repeated-duty applications that require responsive motion, steady regulation, and compact installation within servo-controlled equipment.
During rated operation, the rotor can reach a nominal speed of 4000 rpm and maintain a continuous standstill torque of 7.2 Nm for static load holding. Feedback to the controller is provided through digital servo feedback, enabling fine-step commutation and diagnosis. Power and signal lines exit on the left side, and a single multi-pin connector carries both phases and encoder lines, simplifying cabinet wiring. Standard dynamic balancing keeps vibration within ISO limits, and the housing uses the standard enclosure configuration for this frame. Size code 090 and motor length code B correspond to the active stack height and mounting footprint, while an internal shaft seal limits lubricant migration along the output journal.
A blocking brake is fitted, delivering a holding torque of 11.0 Nm so vertical axes remain fixed when power is removed. The centering flange has a diameter of 110 mm, allowing precise alignment with gearboxes or machine frames. Mechanical output is provided through a plain shaft in a standard single-ended configuration; the opposite end is closed, and no side-B extension is present. The unit is a motor for digital drive controllers, so its electrical parameters and feedback format match compatible Rexroth drive families without additional interface hardware. Its brake and flange arrangement supports installations where the shaft must remain aligned and stationary during power loss or machine stops.
