Product Description:

The MDD090A-N-040-N2M-130GA1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor intended for digital drive controllers, it supplies rotational power with feedback signals that let the controller close position and velocity loops in automated machinery, packaging lines, and material-handling axes. This arrangement supports accurate motion control in applications that require repeatable starts, stops, and speed changes during normal machine operation.

The motor’s mechanical framework includes a centering pilot of 130 mm, which allows precise alignment inside a machine frame. At standstill, it can maintain a continuous torque of 3.7 Nm, so low-speed holding and indexing tasks remain stable without additional gearing. When the shaft reaches its rated operating speed of 4000 rpm, the electromagnetic design keeps thermal loading within the limits of the A-length housing. A spring-applied brake delivers 6.5 Nm of static holding torque, permitting safe parking during power interruptions. The motor uses size code 090, which corresponds to this frame size and mounting format.

Electrical feedback to the drive is handled through digital servo feedback generated by an integrated multi-turn absolute encoder, so the axis reports its position immediately after power-up without a homing move. Power and signal cables exit on side A through a keyed connector, which helps simplify cable routing when several axes are installed close together. A factory-installed shaft seal works with the plain steel shaft to help block lubricants and fine particulates from reaching internal components. The housing uses standard balancing, which helps reduce vibration as the rotor accelerates. The A-length stator section also keeps the motor compact enough for installations where mounting space is limited.
