Product Description:

The MDD090A-N-040-N2M-110PL0 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a permanent-magnet synchronous motor intended for use with digital drive controllers where precise speed and position control are required in automated machinery and handling systems. In servo applications, the motor converts regulated current into controlled rotary motion for indexing units, feed axes, and compact transfer mechanisms. Its closed-loop operation supports repeatable motion in equipment that must maintain stable response during acceleration, deceleration, and dwell periods.

This model delivers a continuous standstill torque of 3.7 Nm, so the axis can hold or slowly index a load without thermal overload. Under rated electromagnetic excitation, the rotor reaches 4000 rpm, giving moderate operating speed for compact packaging and transfer equipment. Position data are produced by an integrated multi-turn absolute encoder, which provides multi-revolution feedback without battery support. The signal is sent to the drive through digital servo feedback (DSF), which supports accurate position and speed regulation during demanding motion profiles. Power, feedback, and brake conductors terminate on a single rugged connector, and all connections are located on the left side of the stator housing to simplify cable routing when motors are mounted in parallel rows.

The flange has a centering diameter of 110 mm, allowing precise seating on machine or gearbox interfaces while maintaining shaft alignment. For environmental protection, the motor uses a shaft seal that helps limit lubricant loss and contaminant ingress. The output shaft includes a keyway so torque can be transmitted through standard keyed couplings, and mechanical vibration is limited by a standard balancing grade that matches common industrial tolerances. The motor is supplied without a blocking brake, so holding force must be provided externally when power is removed. It also uses a single-ended shaft without a side B extension, which helps keep the overall length compact.
