Product Description:

The MDD093D-N-040-N2L-110PR0 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a brushless AC motor intended for use with digital drive controllers in automated machinery that requires rapid speed changes and precise positioning. In this configuration, the motor converts controller commands into rotary motion for tasks such as gantry axes, packaging stations, or tool spindles. Its brushless design eliminates mechanical commutation parts, which supports consistent response during repetitive motion cycles.

The motor reaches a nominal velocity of 4000 rpm, allowing high-cycle positioning without mechanical overspeed. At standstill, it can deliver 24.0 Nm of continuous torque, so static holding or low-speed creep loads remain within thermal limits. A centering diameter of 110 mm mates the flange to standard planetary gearboxes or adapter plates and helps keep radial runout low. Power and feedback connectors are mounted on the right side, which supports straightforward cable routing when the control cabinet is placed on that side of the axis. Signal resolution is supplied by digital servo feedback (DSF), allowing the drive to close both speed and position loops with fine granularity.

The motor uses standard dynamic balancing, which helps limit vibration in general-purpose installations. The output shaft is a shaft with a keyway, providing a positive mechanical interface for pulleys or couplings. Contaminant ingress at the bearing face is limited by a design with a shaft seal, helping preserve internal grease life when dust or coolant mist is present. Frame code 093 indicates the stator diameter, while motor length code D indicates the active stack height that supports the stated torque. The housing is standard ventilated aluminum, and there is no blocking brake, so external holding hardware is required when power is removed. A single-ended shaft is provided, and side B remains unequipped to shorten overall length and simplify encoder mounting.
