Product Description:

The MDD090A-N-020-N2L-110PL1 is a servo motor from the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. Designed for use with digital drive controllers, it converts electrical energy into precisely regulated rotary motion for CNC equipment, packaging lines, and pick-and-place axes. It is suited to applications that need repeatable positioning and stable speed control during frequent starts, stops, and short motion cycles. Its 090 frame size supports compact machine layouts, and the A motor length keeps mass low so the axis can respond quickly to commanded acceleration and deceleration profiles.

The motor supplies a continuous standstill torque of 3.7 Nm, allowing it to hold load at zero speed without extra gearing in suitable applications. Under rated excitation, it reaches a nominal speed of 2000 rpm, which is the synchronous mechanical speed available for normal process cycles before field weakening begins. Accurate mounting is supported by a centering diameter of 110 mm, which helps align the housing with the machine interface. Power and encoder conductors exit on the left side through a sealed industrial connector, which can simplify cable routing in tight cabinets or crowded machine frames. Position information is returned through Digital servo feedback (DSF), allowing the controller to manage high-resolution velocity and torque control with closed-loop feedback.

The motor also includes braking and shaft features suited to enclosed industrial equipment. A blocking brake rated at 6.5 Nm provides holding torque when power is removed, which helps secure the axis during stops. Rotor balancing uses a standard grade, and a factory-installed shaft seal helps protect the bearings from coolant or dust entering along the keyway interface. The cast housing withstands normal shop floor contact, and the single-ended shaft leaves no side B extension, which reduces overall motor length and eases coupling in compact drive trains.
