Product Description:

The MDD115A-N-030-N2L-180GB1 is a three-phase permanent-magnet servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is intended for tasks such as coordinated axis motion, spindle drives, and point-to-point positioning in automated assembly lines. Its electromagnetic design supports frequent reversals and precise incremental moves required in industrial robotics and machine tools.

At standstill, the motor can generate a continuous torque of 28.0 Nm, so a connected drive can hold or move loads without overheating under static conditions. During operation, it reaches a nominal speed of 3000 rpm, offering fast cycle times when combined with matching gear stages. For emergency or power-off holding duties, the integrated blocking brake supplies up to 45.0 Nm of countertorque, removing the need for external mechanical locks on vertical axes. The mechanical interface uses a centering diameter of 180 mm, allowing repeatable alignment with standard flange patterns. Power, feedback, and brake wiring leave the housing on side B, which helps route cables away from moving parts while keeping the front face clear. Standard balancing reduces vibration at high rotational speeds.

Feedback accuracy is provided by Digital servo feedback (DSF), giving the controller absolute rotor position data for tight speed loops and rapid interpolation. A plain shaft is supplied instead of a keyed or splined interface, minimizing concentricity error when clamped couplings are used. The motor uses a single industrial connector for power and encoder conductors, reducing assembly time compared with discrete terminals. A dedicated shaft seal is fitted at the output end to limit lubricant escape and protect the internal bearings from dust or coolant ingress.
