Product Description:

The MDD090C-N-040-N2M-130PR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for industrial automation where digital drive controllers require precise rotary motion and repeatable positioning. By converting controlled three-phase electrical input into mechanical torque, the unit drives axes in packaging lines, material-handling systems, and assembly stations. Its integrated feedback and brake components allow compact installation within machines and support controlled motion without separate external sensing devices.

At a continuous standstill rating of 10.4 Nm, the motor can hold or slowly index loads without overheating. Under rated excitation, it reaches a nominal speed of 4000 rpm, meeting fast cycle-time requirements. Accurate mechanical alignment is aided by a centering diameter of 130 mm, and service wiring is simplified because the power and feedback connectors are mounted on the right side. The electrical interface uses a sealed connector, while standard dynamic balancing minimizes vibration in high-speed assemblies. A standard housing encloses the frame, and a shaft seal helps prevent coolant or dust ingress at the output. The motor has a size code of 090, and the shaft end is supplied only on side A, which helps avoid overhung loads at the rear.

The integrated multiturn absolute encoder reports position over digital communication, and the unit includes a blocking brake that supplies 6.5 Nm of holding torque during power-off stops. Position data is relayed through DSF, allowing the drive to close velocity and position loops without external sensors. Length code C identifies the stack depth used for this torque class, while a keyed output shaft with a keyway transmits torque to pulleys or couplings. This arrangement supports accurate position tracking and stable holding at standstill in closed-loop drive systems.
