Product Description:
The MDD112B-N-030-N2M-130PB2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded three-phase current into regulated rotary motion for automated transfer lines, packaging stations, and CNC machinery. Integrated feedback and braking features allow the unit to support closed-loop axes where precise positioning, quick reversals, and consistent speed control are required. This makes the motor suitable for applications that need repeatable motion together with controlled stopping at standstill.
The front flange uses a centering diameter of 130 mm, which helps position the motor accurately on a mounting surface. The aluminum housing uses the standard cooling surface profile for the series, and a shaft seal helps block dust and coolant from reaching internal components. Electrical terminations face the rear because the power and feedback connections are on Side B and use a single Connector interface, which can simplify cable routing in compact machine layouts. The motor has size 112 with length code B, giving this unit the stack length used for its frame. Under continuous stall conditions, the rotor delivers 17.5 Nm of torque, and the winding reaches a rated speed of 3000 rpm when operated from a compatible inverter. The shaft end is standard, and no second shaft projects from the rear.
A blocking brake rated at 40.0 Nm holds the axis when power is removed, which suits vertical or indexing duties where unwanted movement must be prevented. Positional data are produced by an integrated multiturn absolute encoder and transmitted through digital servo feedback (DSF) to the controller, so the drive can track shaft position across multiple revolutions. Torque is transferred through a keyway shaft for positive coupling to pulleys or hubs. The motor is supplied with the brake installed and with a shaft seal in place, so the unit arrives ready for mechanical mounting and connection to the drive system.
