Product Description:

The MDD090A-N-030-N2M-130PL0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Within an automation cell, it pairs with digital drive controllers to translate electrical command signals into controlled rotary motion for axes that require precise speed and torque regulation. The motor belongs to size 090 of the platform, uses a standard housing, and follows a standard balancing scheme to limit vibration during repeated motion. Its closed-loop operation allows the matched drive to correct speed variation as load conditions change during travel and dwell.

The motor delivers 3.7 Nm of continuous standstill torque, allowing the drive to hold loads while staying within thermal limits. Under rated excitation, the rotor reaches 3000 rpm, which supports rapid positioning on light-to-medium inertia axes. A centering flange of 130 mm simplifies concentric mounting, and stack length code A keeps overall depth compact while the size 090 frame still provides adequate thermal surface. Power and feedback cabling exit on the left side through a sealed Digital servo feedback (DSF) connector, which helps route cables away from crowded machine sections and reduces strain at the connection point.

Position data is resolved by an Integrated multiturn absolute encoder, so the controller retains rotor angle after power cycling. The mechanical interface uses a shaft with a keyway and is supplied with a shaft seal to support direct coupling while helping limit lubricant migration near the bearings. A single-ended shaft is provided on side A, and there is no extension on side B, which leaves the rear of the motor reserved for the feedback assembly. Stopping torque is generated electrically because the unit is without a blocking brake, which keeps rotating mass low for quick acceleration and short response times.
