Product Description:

The MDD112D-N-020-N2L-130PB0 is a synchronous servo motor from Bosch Rexroth Indramat’s MDD Synchronous Motors series. As a motor for digital drive controllers, it converts precisely regulated armature current into controlled mechanical output, allowing automated equipment to position loads accurately and maintain commanded velocities across repetitive production cycles. It is suited to servo axes that require repeatable starts, stops, and speed changes under varying load conditions.

The motor has a centering pilot diameter of 130 mm, giving a large contact surface that helps align the stator face to mounting fixtures with minimal radial runout. Power and feedback conductors exit on Side B, and this rear-facing orientation helps keep cables clear of moving machine elements on many layouts. A plug-in Connector simplifies wiring because no terminal strip work is required. At standstill, the unit can deliver 38.0 Nm of continuous torque, so it can sustain heavy static loads while the drive holds position. During motion, the rotor reaches a rated speed of 2000 rpm, which matches common gear ratios used in transfer lines and packaging stations. Standard dynamic balancing reduces vibration across that speed range and helps protect the bearings.

The motor is supplied without a blocking brake, so any load holding after power is removed must be provided by the drive or by an external locking device. Position data is returned through digital servo feedback, supporting precise commutation and stable velocity control. Power is transmitted through a keyway shaft that mates with keyed couplings to help prevent slipping under peak torque. A compliant elastomer lip, supplied with a shaft seal, helps block coolant spray and fine dust from entering the front bearing chamber. The size 112 frame with length code D follows the standard series envelope, and the drive-side shaft end is arranged without a side-B extension to keep the overall length compact.
