Product Description:

The MDD090B-N-030-N2L-110GL0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts command current from an inverter into proportional torque for positioning and velocity loops in automated machinery. Its 090 frame size with B length gives a mid-length stator that suits compact but demanding axes such as pick-and-place arms, packaging stations, and small transfer lines. In closed-loop motion systems, this arrangement allows fast response to changing load demands and repeated start-stop cycles.

The stator body is dynamically balanced to a standard grade, and the machined centering pilot measures 110 mm, enabling repeatable concentric mounting on gearbox flanges or machine plates. At standstill, the electromagnetic system can deliver 7.2 Nm of continuous torque, which supports holding force during dwell periods without overheating. Under rated excitation, the rotor reaches a nominal speed of 3000 rpm, supporting rapid cycle rates while staying within the permissible mechanical envelope. Position data are returned through digital servo feedback, so the drive can close high-resolution loops without an external encoder. A plain shaft transmits motion directly to couplings or belt pulleys and helps minimize backlash. The aluminum housing is the standard sealed style and dissipates heat through natural convection.

Electrical and feedback conductors exit on the left side through a keyed connector, which simplifies cable routing when multiple axes are stacked. The keyed connection also helps maintain correct mating orientation at the motor interface. Because the unit is supplied without a blocking brake, holding force for vertical loads must be provided by drive torque or an external clamping device. There is a shaft seal around the output journal to limit lubricant migration in oil-sprayed environments. The shaft end uses the standard single-sided configuration, so no extension is provided on side B.
