Product Description:

The MDD090B-N-020-N2L-110PR0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts precisely modulated three-phase current into controlled rotary motion for indexing tables, gantry axes, and other industrial automation equipment. The unit is intended for use with compatible Rexroth inverters, where it provides the mechanical output stage required for accurate positioning and stable speed regulation. Its synchronous design supports repeatable motion in applications that need consistent response during both start-stop cycles and continuous operation.

At standstill, the unit produces a continuous torque of 7.2 Nm, allowing low-speed holding without excessive temperature rise. Under rated excitation, it reaches a nominal speed of 2000 rpm, which suits medium-throughput handling and positioning tasks. The motor can draw up to 48.6 A during acceleration, so the connected drive and conductors must support that current demand. Its torque constant is 0.86 Nm/A, which gives a predictable relationship between motor current and developed torque. Digital servo feedback supplies rotor position data to the controller, while F-class insulation supports dependable thermal performance during continuous duty. Standard rotor balancing also helps keep running behavior smooth across the operating range.

The motor uses a 110 mm centering pilot for accurate alignment during mounting and has an IP65 enclosure to resist dust and water spray. Power and feedback leads exit on the right side through the mounted connector, which can simplify cable routing in machines with fixed harness paths. The stator has an inductance of 10.1 mH and a resistance of 1.99 ohms, and these values influence current ripple and heat generation in the winding. Torque is transmitted through a shaft with a keyway and a shaft seal to help retain lubricant and limit contamination at the bearing area. The motor does not include a blocking brake, uses the standard housing, and follows the B-length 090 frame format with a single side-A shaft end.
