Product Description:

The MDD090B-N-020-N2L-130PA0 is an AC synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to operate with digital drive controllers, it converts commanded currents into precise shaft motion for positioning, packaging, and material-handling axes. Its construction supports rapid torque changes, letting automated equipment hold position accurately and follow programmed speed profiles used in CNC and assembly machinery.

It uses standard rotor balancing to limit vibration during high-speed operation. The centering pilot measures 130 mm, allowing the motor to seat against gearboxes or adapter plates. Electrical and encoder leads exit on side A, so cable bundles follow a fixed path inside the cabinet or machine frame. At standstill, the winding delivers 7.2 Nm of continuous torque, and the stator is sized to sustain that value with natural convection from its standard housing. Under rated excitation, the rotor reaches a nominal speed of 2000 rpm. Position data comes from integrated Digital servo feedback (DSF), enabling closed-loop drives to track shaft angle with high resolution. A shaft seal protects the front bearing from lubricant splash and fine particles.

The power and signal cores terminate in a rear connector rather than flying leads, which helps keep wiring organized. A keyed shaft end with a keyway transmits torque without slippage, and there is no shaft extension on side B. The motor is supplied without a blocking brake, so auxiliary holding devices must be used if static retention is required. Frame size 090 and motor length code B give a compact envelope that fits shallow machine bays while accommodating the laminated core needed for the specified torque density. Standard housing materials and surface finish resist shop contaminants without additional coatings.
