Product Description:

The MDD090B-N-030-N2M-110PR2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts electrical commands into precise rotary motion for pick-and-place axes, tool changers, and packaging stations. Its synchronous operating principle supports accurate speed regulation and repeatable positioning during closed-loop machine motion. This makes the motor suitable for automated equipment that depends on smooth acceleration and reliable tracking under changing load conditions.

This model uses a centering pilot of 110 mm to align the housing to machine frames and reduce radial runout during high-speed operation. During static holding or slow creep, it can deliver a continuous standstill torque of 7.2 Nm, allowing the drive to support loads without overheating. At its rated operating point, the rotor can maintain a nominal speed of 3000 rpm, which matches the range used by typical Indramat drive amplifiers. A blocking brake integrated on the non-drive end provides up to 11.0 Nm of braking torque when engaged, helping secure vertical or suspended loads. Rotor position is returned to the controller through Digital servo feedback (DSF) so the control loop can make high-resolution velocity and position corrections.

Power and feedback conductors exit on the Right, allowing cables to be routed away from moving parts, and the interface uses a DIN-style connector for a compact electrical connection. Rotor equilibrium uses standard balancing, and the cast housing follows the 090 frame with B-length proportions used for common mounting arrangements. An integrated multiturn absolute encoder records shaft position over multiple revolutions, which helps the control system retain position information after a power loss. The shaft has a keyway for positive-drive couplings and a shaft seal to help prevent lubricant leakage into the motor interior. A single-ended shaft without a side-B extension simplifies coupling alignment and reduces overhung load on the bearings.
