Product Description:

The MDD090C-N-030-N2M-130GB2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a component for digital drive controllers, the unit converts electrical power into precise rotary motion for positioning tables, gantries, and packaging axes in automated systems. It uses permanent-magnet excitation and an internal feedback loop to maintain commanded speed and torque under changing load. This arrangement supports accurate motion during repeated starts, stops, and speed changes. It is suited for applications that require controlled acceleration and repeatable stopping accuracy.

The motor has a rated speed of 3000 rpm, allowing high rotor speed while staying within its thermal limits. A continuous standstill torque of 10.4 Nm provides holding force for static loads and controlled motion at very low speed. Position data is returned through digital servo feedback (DSF) from an integrated multiturn absolute encoder, so the drive can track shaft position across multiple revolutions. The housing uses a centering pilot of 130 mm for accurate alignment, and power and feedback lines exit through a keyed connector on side B. That combination supports positioning tasks that need both quick movement and stable low-speed control.

The motor includes a blocking brake that provides 11.0 Nm of holding torque when power is removed, which is useful on axes that must remain fixed at standstill. It uses a plain shaft for direct coupling to compatible machine elements and gearboxes. A shaft seal at the output end helps separate lubricant from contaminants and supports the standard IP65 housing protection. The sealed output end also helps protect the bearing area during operation in dusty environments. Balancing is standard, and the motor uses size 090 with length code C for its frame geometry.
