Product Description:

The MDD090B-N-030-N2L-130PL1 belongs to the MDD Synchronous Motors series from Bosch Rexroth Indramat. Classified as a motor for digital drive controllers, it converts commanded current into rotary motion for positioning and velocity-regulated axes in automated machinery. The unit suits applications that need compact dimensions and repeatable speed, and its integrated digital position feedback returns diagnostic and control data to the motion controller. This feedback path helps the drive correct speed changes quickly during acceleration, deceleration, and load variation, which supports stable servo operation across repeated cycles.

A centering pilot of 130 mm aligns the flange, and all power and feedback leads exit on the left side through a connector so cable routing can follow a fixed path. At standstill, the electromagnetic structure supplies a continuous torque of 7.2 Nm, allowing stable holding or low-speed movement without thermal saturation. During operation, the resolver-based control loop exchanges position data through digital servo feedback (DSF), while the stator can accelerate the rotor up to 3000 rpm for high-cycle duty. A rotor balanced to the standard grade helps reduce vibration during rapid speed changes. The housing and shaft seal are standard, the shaft end is provided only on side A, and motor length code B supports medium-inertia loads.

For static safety, the integral blocking brake supplies 6.5 Nm of holding torque, preventing drift when the axis is powered down or used on a vertical load. Power transmission to the driven element uses a shaft with a keyway, which simplifies coupling alignment and supports secure torque transfer. The frame code 090 matches the stator cross-section and fits assemblies that share the same mounting geometry. Because the motor uses a single shaft end, surrounding machine components can be arranged without an output extension on the opposite side, which helps keep the installation compact and straightforward.
