Product Description:

The MDD090A-N-040-N2M-130GL0 is a synchronous servo motor produced by Bosch Rexroth Indramat and placed within the MDD Synchronous Motors series. In closed-loop drive systems, this motor converts commanded current from a digital drive controller into mechanical motion for positioning tables, pick-and-place arms, or packaging spindles. Its synchronous design supports accurate speed and position control in automated axes that require repeatable rotary movement during continuous production. This type of motor is commonly used where fast response, steady torque delivery, and reliable feedback integration are needed to maintain axis accuracy under changing load conditions.

For mounting accuracy, the front flange carries a centering diameter of 130 mm. All power and feedback connectors are oriented on the left side, which can simplify cable routing in compact machine layouts. The unit uses a plug-in connector interface rather than fixed leads, which helps keep installation points organized around the motor housing. Its stator winding provides a continuous standstill torque of 3.7 Nm, giving the motor enough holding force for lightly loaded axes without external gearing. The motor reaches a nominal mechanical speed of 4000 rpm, which supports short-cycle applications and rapid return strokes on compact automation equipment.

An integrated multi-turn absolute encoder supplies position data through digital servo feedback (DSF), allowing the connected drive to read rotor position immediately after power-up. This feedback arrangement supports stable closed-loop regulation during motion and helps the axis maintain accurate positioning during repeated starts and stops. The motor is supplied without a blocking brake, so holding torque must come from the drive or an external clamp when power is removed. A plain output shaft is fitted with a shaft seal to help protect against coolant splash and dust at the shaft exit. The standard housing with size 090 lamination and A motor length keeps the assembly compact and helps limit inertial loading on moving axes.
