Product Description:

The MDD090C-N-030-N2L-130PB0 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a permanent-magnet AC servo motor intended for use with digital drive controllers in automated machinery. In that role, it converts commanded current into precise rotary motion for positioning tasks and velocity loops on packaging lines, tooling axes, and material-handling stages, while supporting accurate motion control under changing load conditions.

This model uses a centering pilot of 130 mm, giving the mounting flange a fixed reference that aligns the stator with adjacent mechanics. Power and feedback leads exit on Side B, so the machine layout must reserve clearance on that face, and the single-plug connector allows the motor to be connected without separate core terminations. At standstill, it produces 10.4 Nm of continuous torque, which indicates the load it can hold without exceeding thermal limits. The rotor is balanced to a standard grade to reduce residual vibration during cyclic duty. For stop-state retention, the shaft relies on drive torque alone because the motor is supplied without a blocking brake, which removes the weight and inertia of an internal brake pack but requires external mechanical locking when power-off holding is necessary.

Closed-loop position data are generated by the integrated Digital servo feedback system, which streams high-resolution signals to the controller for tight loop gains. Under rated excitation, the rotor reaches a nominal speed of 3000 rpm, matching many standard ball-screw and belt transmissions without gear reduction. The shaft uses a keyway profile so couplings can transmit torque without slip, and it is fitted with a shaft seal to prevent lubricant loss and dust ingress along the journal. Size code 090 and length code C indicate the motor's active iron volume, while the standard housing supports heat transfer to the mounting surface.
