Product Description:

The MDD090B-N-040-N2L-130GB0 is a servo motor produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. It is built to work with digital drive controllers in industrial automation lines, where it delivers commanded torque and speed to linear or rotary mechanisms. The unit serves as an electromechanical actuator that converts drive current into precise shaft rotation for positioning, cutting, or conveying stations. This arrangement allows the paired control system to regulate axis motion directly at the motor during frequent direction changes.

At standstill, the motor can supply a continuous torque of 7.2 Nm, giving machinery the ability to hold or slowly advance loads without overheating. When driven by rated current, it reaches a nominal speed of 4000 rpm, a value suited for high-cycle pick-and-place or spindle duties that need repeatable velocity. Mechanical alignment is simplified by a centering diameter of 130 mm, while standard balancing helps reduce vibration at the mounting interface. Power and feedback conductors exit on side B of the housing, and the electrical interface uses a removable connector. The B-length stator and 090 frame size keep the motor compact, and the unventilated housing helps limit the entry of contaminants.

Integrated digital servo feedback (DSF) sends absolute position data to the drive so the control loop can maintain accurate speed and position without an external encoder. The motor is supplied without a blocking brake, so any holding function at standstill must come from the drive or from external clamping hardware. A front shaft seal helps limit the entry of dust or coolant near the bearing area. The output uses a single plain shaft without a side B extension, which helps keep the overall motor length short and leaves only one shaft end for coupling.
