Product Description:

The MDD090A-N-020-N2M-130PL1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts regulated DC power into controlled rotation for positioning and feed axes. Motor size 090 with length code A allows installation in tight machine frames while preserving responsive motion. Integrated multi-turn absolute feedback supplies position data for closed-loop control, and the built-in brake supports load holding when power is removed. It is appropriate for compact automation equipment that depends on stable servo regulation during frequent starts and stops.

At standstill, the motor can supply 3.7 Nm of continuous torque, allowing the axis to hold force without exceeding winding temperature limits. During motion, it reaches a nominal speed of 2000 rpm, which supports steady cycle timing on feed and positioning axes. When input power is removed, the blocking brake applies 6.5 Nm of holding torque to keep the shaft from drifting. Mechanical alignment is centered on a 130 mm pilot diameter for accurate mounting with couplings or gearboxes. Position and velocity signals are returned through digital servo feedback (DSF), allowing the controller to close precise motion loops without external transducers.

For installation, the power and feedback cables exit on the left side, and a keyed connector supports straightforward cable attachment. The rotor uses standard balancing, which supports smooth running with rigid couplings. An oil-resistant end cap with a shaft seal protects the front bearing from coolant splash and helps keep contaminants away from the motor interior. A keyway shaft end transfers torque directly to pulleys or pinions, and the lack of a side-B extension keeps the overall length short for compact multi-axis assemblies. The housing is supplied in the standard design used for this frame.
