Product Description:

The MDD115C-N-020-N2L-130PB2 is a servo unit manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it serves as the electromechanical actuator that turns commanded current from the controller into precise rotational motion on automated lines, packaging equipment, and material-handling stations. The housing is supplied in the standard configuration for general-purpose mounting.

Its continuous torque capability reaches 47.0 Nm, allowing the shaft to maintain load at zero speed without overheating. During operation, the rotor can accelerate until the rated mechanical limit of 2000 rpm, which is the synchronous speed reference used by the accompanying drive. A blocking brake is integrated and can hold the axis with up to 60.0 Nm when power is removed, preventing back-driving on vertical or suspended masses. Mechanical coupling accuracy is helped by a centering seat of 130 mm in diameter that aligns the stator with the mounting flange. The frame code of 115 identifies the stator lamination size and places this model in the higher-torque range of the MDD series.

Closed-loop control is supported by digital servo feedback (DSF), which returns precise rotor position data to the drive. Power and feedback conductors exit toward the rear because the connections are on Side B, and the connector interface supports straightforward cable attachment. The steel shaft uses a keyway to transfer torque to pulleys or couplings, and a shaft seal is fitted to help prevent oil ingress from the machine. Rotor mass is balanced to the standard grade, keeping vibration within allowable limits even with the C-length stator package. The design omits a second shaft extension, leaving the side opposite the load end blank for compact mounting.
