Product Description:

The MDD090B-N-030-N2M-110GR0 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for use with digital drive controllers, it supplies closed-loop torque and speed for positioning tasks in automated machinery. The motor fits handling systems, packaging equipment, and machine tools where repeatable rotary motion is required. Its size code 090, length code B, standard housing, and standard rotor balancing give it a compact footprint and stable running behavior. That combination suits indexing, feed motion, and synchronized axis movement in production equipment.

Its continuous stall capability is 7.2 Nm, which allows the rotor to hold load at zero speed without thermal overload under rated conditions. During dynamic operation, the motor reaches a nominal speed of 3000 rpm, which suits many servo applications that require fast positioning and steady response. Mounting is centered by a 110 mm pilot diameter, helping the housing seat accurately against machine interfaces. Position information comes from an integrated multi-turn absolute encoder, so the drive can retain shaft position over multiple revolutions after power cycling. Mechanical output is provided through a plain shaft for direct coupling to the driven load.

The motor uses digital servo feedback (DSF) for high-resolution position control in the drive controller. It is supplied without a blocking brake, so vertical or suspended loads need an external holding method when power is removed. Power and feedback cables leave on the right side of the stator and terminate in a single connector, which keeps cable routing compact around the motor body. A factory-installed shaft seal helps protect the output journal from dust and coolant during routine machine operation. The sealed output end also helps protect nearby bearing areas where splash, fine dust, or residue may be present during regular use.
