Product Description:

The MDD090A-N-020-N2L-130PL2 is a synchronous servo motor produced by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Designed as a drive element for digital controllers, the unit converts commanded current into precisely regulated rotary motion for automated axes, tooling spindles, and transfer stations. Position data are returned through integrated digital servo feedback, allowing the controller to maintain accurate speed and position control during operation. This arrangement supports repeatable motion in machinery that runs frequent start-stop cycles or coordinated axis movements.

The motor uses size 090 with the short A-length frame, so it fits installations with limited axial space while still providing the torque expected from this diameter class. Standard rotor balancing helps reduce vibration during high-cycle positioning tasks and supports smooth running in compact machine layouts. A centering shoulder of 130 mm supports concentric mounting to gearboxes or machine plates, and all electrical terminations exit through a sealed connector on the left side to keep cable routing consistent in multi-axis cabinets. Continuous stall capability reaches 3.7 Nm, which allows the motor to hold static loads during dwell periods without overheating. The housing uses the standard enclosure form, and the shaft is supplied in a standard single-ended configuration without a side B extension.

An internal blocking brake provides 11.0 Nm of mechanical holding torque when power is removed, helping prevent axis drift on vertical or suspended loads. Rated operation reaches 2000 rpm, which suits common speed ranges in gantries, presses, and other automated motion systems. The output uses a keyway shaft for positive torque transmission to pulleys or couplings without slip during load changes. A fitted shaft seal helps limit contamination ingress at the output end during service. The brake and shaft arrangement support stable standstill behavior while preserving a straightforward mechanical connection to the driven load.
