Product Description:

The MDD112D-N-020-N2L-130PL0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into controlled mechanical rotation on automated axes. Used with Rexroth drive electronics, the unit supplies regulated torque and velocity for positioning tables, gantry stages, and material-handling mechanisms in industrial automation. This makes it suitable for repeatable motion tasks that depend on smooth speed regulation and accurate positioning over frequent duty cycles.

This model delivers a continuous standstill torque of 38.0 Nm, allowing the axis to hold static loads without external brakes during normal energized operation. Under rated excitation, the rotor reaches a nominal speed of 2000 rpm, a value that matches common transmission ratios in packaging and assembly lines. Accurate mechanical registration is supported by a centering diameter of 130 mm, which helps keep the housing aligned with the machine flange. All power and feedback leads exit on the left side, so cabinet layouts can keep cable bends consistent. Position information is returned through digital servo feedback (DSF), which supplies high-resolution incremental data to the drive for closed-loop control. Motion is transferred through a shaft machined with a keyway, simplifying coupling to gearboxes or belt pulleys while preventing rotational slip.

The motor is supplied without a blocking brake, so the application must rely on drive torque or external clamping to maintain position during power-off states. The frame belongs to size 112 with length code D, giving moderate inertia that balances dynamic response with load capability. Electrical terminations are made through a sealed connector, and a shaft seal is fitted to limit lubricant escape and the ingress of dust or coolant. Standard housing and balancing grades permit mounting in any orientation without supplemental vibration treatment. The sealed electrical interface also helps protect the cable connection in enclosed machine spaces.
