Product Description:

The MDD090B-N-040-N2M-110PL2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into repeatable torque and speed, allowing automated cells to position loads with electrical accuracy rather than relying on mechanical gearing. This role places the unit in gantries, pick-and-place stations, and other motion axes that require direct coupling between controller commands and rotor response.

In continuous operation, the rotor can deliver 7.2 Nm of torque while remaining thermally stable at standstill. During acceleration or vertical holding, the integrated blocking brake supplies 11.0 Nm of static torque to secure the shaft when power is removed. A nominal speed of 4000 rpm sets the operating speed used by the drive system during normal motion. Position data come from an integrated multi-turn absolute encoder that feeds the controller through digital servo feedback, so the drive receives position information immediately after power returns. Mounting accuracy is aided by a centering diameter of 110 mm, and the frame size of 090 places the motor within the corresponding housing class of the series.

The motor uses a Standard balance grade to help limit vibration during operation. Its overall length follows code B, which gives the housing the corresponding axial dimension for this frame. Power and feedback conductors exit on the left side through a sealed industrial connector, which can simplify cable routing in compact machine layouts. The housing is standard, and the shaft end is provided only on side A. A shaft seal helps prevent lubricant migration into the motor interior, while the keyway shaft supports positive torque transmission to pulleys or couplings without slip.
