Product Description:

The MDD090C-N-030-N5M-110GB2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it generates controlled rotary motion for positioning axes and feed drives in automated machinery. Its internal feedback device supplies the controller with the position data needed to regulate velocity and torque. An integrated holding brake secures the connected load when motor power is removed. The sealed housing allows the motor to be mounted directly on mechanical assemblies exposed to typical industrial operating conditions.

This model supplies a continuous standstill torque of 10.4 Nm, so it can hold or slowly move loads without overheating while the shaft remains stationary. During normal operation, the rotor reaches a nominal speed of 3000 rpm, matching drive controllers that supply the required electrical frequency for the motor’s pole count. The built-in brake produces 11.0 Nm of static torque, keeping vertical or suspended loads in place when power is removed. A centering diameter of 110 mm aligns the flange with gearboxes or machine plates during installation. All power and feedback leads exit on side B, simplifying cable routing when the motor is installed in a compact machine layout.

Signal quality is maintained by the integrated multiturn absolute encoder, which reports the shaft position over multiple revolutions without requiring a homing cycle. Torque is transferred through a plain shaft that eliminates the stress concentrations associated with a keyway in high-cycle applications. The rotor has standard balancing, which minimizes vibration when the motor operates at working speed. Position data reaches the controller through digital servo feedback (DSF), allowing high-resolution closed-loop control and automatic parameter recognition during system setup. A shaft seal prevents lubricant migration and protects the motor interior from fine dust and coolant spray during continuous industrial service. These features support accurate feedback transmission while helping the mechanical interface withstand repeated operation in automated equipment.
