Product Description:

The MDD090A-N-030-N2L-130PB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it accepts commanded current from an Indramat inverter and converts that energy into controlled rotary motion for positioning tables, packaging axes, and similar industrial automation tasks. It has motor size 090 and length code A, which indicates the shortest stator stack in this frame and helps reduce mass and inertia for rapid acceleration.

A centering diameter of 130 mm provides repeatable alignment against mounting flanges, and the rotor uses standard balancing quality to limit vibration during high-speed operation. Power and feedback conductors exit on Side B through a single connector, simplifying cable routing. At standstill, the motor can deliver 3.7 Nm of continuous torque, which is enough for light-to-medium holding loads without overheating the standard housing. Because it is supplied without a blocking brake, mechanical clamping or drive torque must maintain position when power is removed.

For position control, the motor uses digital servo feedback, giving the drive high-resolution rotor angle data needed for tight velocity loops. The electrical design supports operation up to 3000 rpm, and within that speed range the drive can command full torque without loss of synchronism. A shaft with a keyway transmits torque through standard couplings, and the front bearing region is protected with a shaft seal to block coolant splash or lubricating oils. The shaft end uses the standard layout, and no secondary shaft is present on the rear, matching typical single-ended gearbox or pulley assemblies. The standard housing keeps weight low, and the connector arrangement leaves the opposite side clear for routing coolant hoses or mechanical guards.
