Product Description:

The MDD090B-N-020-N2L-110PB1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for operation with digital drive controllers, the unit turns commanded electrical energy into precisely regulated rotary motion for positioning and speed-controlled axes in automated machinery. Its integrated feedback supports stable closed-loop operation during repeated starts, stops, and speed changes. That makes the motor suitable for packaging lines, material-handling stages, and other industrial stations that require repeatable motion over long operating cycles.

The motor supplies a continuous standstill torque of 7.2 Nm, allowing loads to be held or slowly indexed without thermal overload during long dwell periods. Under rated excitation it attains a nominal speed of 2000 rpm, which suits medium-inertia duties where smooth velocity profiles are important. Power and signal conductors exit at Side B, which can simplify cable routing when the opposite face is blocked by adjacent machine elements. Rotor position is reported through Digital servo feedback (DSF), enabling the drive to correct current vectors during each control cycle. Output torque reaches the machine through a shaft machined with a keyway, giving positive engagement to pulleys or gear hubs. Standard balancing and a standard housing help keep vibration low during general-purpose operation.

An integral blocking brake delivers 6.5 Nm of static torque to secure vertical or oscillating loads whenever the controller is disabled. Accurate flange alignment is supported by a centering diameter of 110 mm, helping maintain coaxial assembly with gearboxes or adapter plates. Service conductors attach through a round connector that locks to the housing, and the output end is fitted with a shaft seal to help limit lubricant migration along the shaft. The motor uses size 090 with length code B and a single-ended shaft arrangement for standard machine installation.
