Product Description:

The MDD093C-L-030-N2L-130PB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It uses the 093 frame size with C length and is intended for digital drive controllers in positioning tables, packaging machinery, and other closed-loop automation axes where accurate speed and position control are required. In operation, the motor converts regulated electrical input into rotary motion for synchronized machine movement. An integrated blocking brake holds the load when power is removed, and the motor has a shaft only on the A-side, so there is no shaft end on side B.

The centering diameter measures 130 mm, allowing the flange to locate accurately on a matching machine register. Power and feedback leads exit on Side B, which helps route cables from that face of the motor. A keyed circular connector carries both motor power and control signals in one interface and keeps the electrical connection compact at the housing. The motor reaches a nominal speed of 3000 rpm, which suits high-response servo operation. For static holding, the spring-applied brake provides 11 Nm of torque to secure vertical loads or resist process disturbances during standby. Standard dynamic balancing limits residual vibration during high-speed cycles.

The housing uses surface cooling, so heat is conducted through the outer frame to the mounting interface rather than removed by an internal blower. This cooling method relies on good thermal contact between the motor and the machine structure. Rotor position is returned through Digital servo feedback (DSF), allowing the drive to maintain high-resolution speed and position control without separate external sensors. Mechanical torque is transmitted through a keyway on the single output shaft, and a factory-installed keyway retaining arrangement helps keep the drive key in place. A labyrinth arrangement combined with a shaft seal restricts dust and coolant ingress at the output journal and helps protect the bearings.
