Product Description:

The MDD090B-N-030-N2M-130PB2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers and uses size 090 with length code B, which gives it a compact form for medium-duty axes. In automated assembly, material handling, and packaging equipment, the motor converts regulated current from the drive into precise mechanical rotation. An integrated multi-turn absolute encoder returns position data to the controller so the axis can maintain accurate closed-loop motion after startup and during speed changes. This layout supports repeatable positioning in applications that alternate between short moves and stable holding periods.

At standstill, the rotor sustains 7.2 Nm of continuous torque to support static loads without auxiliary cooling, while normal operation reaches a nominal speed of 3000 rpm for rapid indexing and steady cycle times. Power and feedback leads exit on side B, and the motor uses a plug-in connector that keeps the cable interface compact at the housing. Motion data is transmitted through digital servo feedback (DSF), which provides absolute and incremental values for closed-loop control. Rear cable exit can help in machines where the mounting face is crowded by couplings, guards, or nearby structural parts. The feedback channel lets the controller monitor shaft movement continuously during acceleration, constant-speed travel, and stopping.

During power-off conditions, a blocking brake supplies 11.0 Nm of torque to prevent unintended motion on vertical or suspended axes. A centering diameter of 130 mm aligns the flange accurately with mating surfaces, and the shaft uses a keyway for positive torque transmission. The motor is built with a shaft seal, which helps keep dust and lubricant away from internal components near the output side. This combination is useful where the axis must remain in place after power is removed. The motor also omits a second shaft end on side B, which keeps the overall length shorter and leaves more space around the rear connection area.
