Product Description:
The MDD090B-N-040-N2M-110PA2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for integration with digital drive controllers, this unit supplies controlled rotary motion for positioning and speed regulation in automated machinery. Its synchronous operating principle allows the paired drive to regulate torque and speed with repeatable response during start, stop, and hold phases. This makes the motor suitable for servo axes that require accurate acceleration, controlled deceleration, and stable holding behavior between repeated machine cycles.
At the mechanical interface, a centering diameter of 110 mm aligns the housing with the mating flange, and the rotor is balanced to a standard grade to minimize residual vibration. Power and feedback conductors exit on side A, and the termination uses a connector so installation can be completed without hardwiring. The motor’s continuous stall capability is 7.2 Nm, allowing it to support static loads without overheating, while a rated operating speed of 4000 rpm supports rapid indexing cycles. These values match the size code 090 and length code B, which keep inertia low while supporting medium torque demand. The standard shaft end lacks a secondary stub on side B, and a shaft seal is fitted to restrict lubricant migration into the encoder chamber.
An integrated multi-turn absolute encoder works with digital servo feedback to return precise position data after every revolution and through power interruptions. Position retention during shutdown is provided by a blocking brake rated at 11.0 Nm, which helps hold vertical or suspended loads when the drive is de-energized. The shaft uses a keyway profile so couplings can transmit torque without slip, and the standard housing protects the internal windings while still enabling natural convection cooling. That feedback arrangement supports immediate position availability when power returns and maintains closed-loop motion quality across a broad speed range.
