Product Description:

The MDD093C-N-020-N2L-130PB1 is a synchronous motor produced by Bosch Rexroth Indramat for use with digital drive controllers. As part of the MDD Synchronous Motors series, it serves as a compact torque source for positioning axes and general-purpose motion tasks in automated machinery. The motor converts drive current into controlled rotary motion while its integrated encoder output allows closed-loop speed and position control within multi-axis automation cells. Its synchronous design also supports stable response during acceleration, speed holding, and repeated indexing moves.

The centering diameter of 130 mm gives the mounting flange a fixed reference point for coaxial alignment with gearboxes or direct-drive loads. Service wiring is routed on Side B, and a single connector carries power, feedback, and brake supply to reduce cable congestion. A blocking brake rated at 11 Nm secures the shaft when power is removed, which helps prevent back-driving on vertical or overhung loads. Nominal operation is specified at 2000 rpm, a speed that suits material-handling and tooling applications that require steady velocity under changing load. Standard balancing helps limit vibration during rotation, the housing uses a standard finish, and the motor includes a shaft seal to help restrict oil or dust entry.

Position feedback is provided through Digital servo feedback (DSF), allowing the drive to read high-resolution rotor position data for precise torque regulation. The motor belongs to frame size 093 and carries length code C, a combination that provides a longer active stack than shorter versions in the same frame. A keyed shaft identified by the keyway designation simplifies coupling to pulleys or rigid hubs without relying only on friction fits. The feedback channel also helps the controller maintain smooth low-speed operation and accurate shaft positioning after command changes.
