Product Description:

The Bosch Rexroth Indramat MDD090B-N-020-N2M-110PA1 is a synchronous servo motor in the MDD Synchronous Motors series designed to operate with digital drive controllers. By converting electrical input into regulated rotary motion, the unit drives machine axes that require accurate velocity and position control. Its mechanical format lets machine builders mount the motor quickly in packaging machines, material-handling gantries, and other equipment that rely on precise closed-loop automation. The synchronous design supports controlled acceleration and repeatable motion during continuous production cycles. It is suited to applications where axis response must remain consistent during repeated starts, stops, and reversals.

At a nominal speed of 2000 rpm, the rotor reaches its rated operating velocity while remaining synchronized with the stator magnetic field. When the shaft is locked, the motor can deliver a continuous standstill torque of 7.2 Nm, providing holding force without excessive heating. A factory-installed blocking brake supplies 6.5 Nm of static torque so the axis can remain secured during power loss or emergency stops. Position data is generated by an integrated multiturn absolute encoder, and real-time velocity information is sent to the drive through digital servo feedback (DSF). This feedback arrangement supports stable control during indexing, positioning, and speed-regulated motion.

The mechanical envelope is organized around a centering diameter of 110 mm, allowing repeatable alignment against gearbox or flange faces. Power and feedback conductors exit on side A through a sealed connector, which helps keep cable routing orderly in compact machine spaces. The shaft uses a keyway profile to transmit torque to couplings or pulleys, and a fitted shaft seal helps keep lubricant away from the stator chamber. Standard balancing and housing construction help limit vibration during normal operation. The 090 frame with B length keeps the housing compact, and the absence of a rear shaft extension leaves more room for adjacent components on multi-axis assemblies.
