Product Description:

The MDD090B-N-020-N2M-110PL1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat. It belongs to the MDD Synchronous Motors series. The motor is intended for use with digital drive controllers, where it provides constant torque and accurate position control for industrial automation axes such as handling modules, packaging stations, and machine tool feeds. In this role, it supports controlled acceleration, steady running, and repeatable stopping on servo-driven equipment. That makes it suitable for applications that require dynamic response together with stable motion during repeated production cycles.

This model delivers a continuous stall torque of 7.2 Nm, allowing the axis to hold load without motion while the winding current stays within its continuous rating. The motor has a nominal speed of 2000 rpm under standard operating conditions. Its centering diameter of 110 mm helps align the motor precisely in a matching mounting pilot. Power and feedback conductors exit on the left side, and the output shaft uses a keyway to transmit torque to keyed couplings or pulleys. Standard rotor balancing helps reduce vibration, and the housing uses the standard version without added cooling fins or special coatings.

The integrated blocking brake supplies 6.5 Nm of static holding torque, which helps prevent axis drift when power is removed. Position sensing is provided by an integrated multi-turn absolute encoder, so the shaft location remains available over multiple mechanical revolutions without a homing routine after startup. Commutation and velocity control use Digital servo feedback (DSF), matching the feedback format used by compatible drives. A shaft seal is fitted at the output end to help limit lubricant escape and reduce the entry of fine dust or liquids. The motor has frame size 090 and length code B, which gives it a compact form for standard machine layouts.
