Product Description:

The MDD090B-N-040-N2L-110GR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed to partner with digital drive controllers, the unit translates commanded current into precisely metered torque for positioning tables, pick-and-place heads, and other automated axes. Its electromechanical structure supports rapid reversals and accurate speed regulation, making it suitable for tightly coordinated multi-axis production cells. Integration is simplified by a footprint that matches the 090 frame class, which helps the motor fit common mounting layouts for this size.

The motor sustains a continuous standstill torque of 7.2 Nm, allowing it to support loads during dwell periods without thermal drift. When supplied with rated current, it reaches a nominal shaft speed of 4000 rpm, which supports fast indexing cycles. A blocking brake integrated at the non-drive end delivers 6.5 Nm of static torque, securing vertical or suspended axes during power-off conditions. Position information is generated by Digital servo feedback (DSF), which returns high-resolution commutation signals to the controller. Mounting is centered by a 110 mm pilot diameter, helping maintain concentric alignment with the machine frame and limiting vibration transfer.

Installation details match common cabinet layouts. The power and feedback leads exit to the right, and a sealed connector interface simplifies cable removal. The shaft is fitted with a shaft seal, using a labyrinth and lip arrangement that limits lubricant migration and helps keep contaminants out of the bearing cavity. The rotor ends in a plain shaft, so torque is transmitted through external clamping or keyed hubs selected by the machine builder. Standard dynamic balancing limits residual vibration, the housing follows the standard form factor, and the shaft end omits a side-B extension to conserve axial space.
