Product Description:

The MDD090B-N-020-N2M-110PR0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it converts controlled current into precise rotary motion for axes used in automated packaging, pick-and-place, and material-handling equipment. Permanent-magnet construction and real-time feedback help the motor maintain accurate position control during repeated starts, stops, and speed changes. This operating profile suits machinery that depends on consistent motion during fast production cycles.

Its continuous standstill capability is 7.2 Nm, allowing low-speed motion without overheating. Under rated excitation, the rotor reaches 2000 rpm, supporting medium-speed feed axes and indexing tasks. The flange has a 110 mm centering diameter for repeatable alignment with gearboxes and mounting faces. Power and feedback pass through a keyed connector on the right side, which can simplify cable routing in compact machine layouts. Position data returns via Digital servo feedback (DSF), allowing the controller to monitor rotor position during operation. Standard dynamic balancing and a ribbed housing help reduce vibration during repetitive motion.

The position loop is further refined by an integrated multiturn absolute encoder, which retains revolution information after power loss and can reduce the need for homing at startup. The output shaft uses a keyway profile and is supplied as the only shaft end, so torque is transmitted directly to a coupling or pulley without a secondary extension. The motor is supplied without a blocking brake, so any holding function must come from the drive or external mechanics when the axis is stopped. A front-bearing shaft seal helps protect internal lubrication and feedback components from contamination. The B length code and 090 frame size establish the motor envelope for installations that must match this housing format.
