Product Description:

The MDD090C-N-040-N2M-130PR0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for installation on digital drive controllers, it converts controlled electrical input into precise rotary motion for automated positioning, conveying, and machining axes in industrial equipment that depends on repeatable speed and position control. Its frame follows the 090 size code and the C length variant, giving the motor a mid-range form factor that fits standard mounting patterns while still supporting the fast response expected in coordinated multi-axis motion systems used in packaging, handling, and general automation layouts.

The motor delivers a continuous standstill torque of 10.4 Nm, so it can hold or slowly move loads without overheating during sustained dwell periods and low-speed process steps. A nominal speed of 4000 rpm supports high-speed spindle and pick-and-place duties where quick acceleration and short cycle times are required. The centering diameter measures 130 mm, providing a rigid interface that helps maintain concentricity between the stator housing and the driven mechanics. Power and feedback conductors exit on the right side, and the single-ended connector arrangement helps simplify cable routing when motors are mounted close together on the same machine section or inside compact enclosures.

An integrated multiturn absolute encoder supplies exact positional data over multiple revolutions, so the axis retains position information after power loss without requiring a homing move at restart. The unit is supplied without a blocking brake, allowing the drive controller to provide dynamic holding torque or an external brake to be used on the load side when the application requires static holding. Position information is transmitted through digital servo feedback (DSF), which supports high-resolution communication with compatible Rexroth drive modules. The output shaft uses a keyway for positive mechanical engagement with standard pulleys or couplings. A shaft seal protects the internal bearings from coolant splash, and the standard ventilated housing uses factory balancing for smooth rotation across the operating speed range and stable running in everyday industrial duty.
