Product Description:

The MDD090A-N-020-N2M-130GA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended to generate controlled rotary motion for digital drive controllers used in positioning axes, packaging equipment, and general automation cells. The motor combines a compact 090 frame size with an internal feedback system, allowing its associated drive to regulate velocity and torque in closed loop. This arrangement supports stable motion control in coordinated multi-axis machines.

The rotor has a nominal speed of 2000 rpm, so the drive can maintain process velocity without exceeding thermal limits. Continuous stall torque reaches 3.7 Nm, which is the load the shaft can support indefinitely while locked. For short stops or emergency holding, the blocking brake supplies 6.5 Nm of static torque and is applied automatically when the drive is disabled. The flange presents a centering pilot of 130 mm, which aligns the housing concentrically with adjacent mechanics. Power and feedback conductors exit on Side A through a keyed circular connector, reducing wiring bends inside tight cabinets.

The motion channel uses an integrated multiturn absolute encoder, and its output is transmitted as DSF, so the controller can read position immediately after power-up without homing. A plain shaft with a factory-installed shaft seal helps prevent lubricant migration while still permitting direct coupling to gearboxes or pulleys. Standard balancing keeps residual vibration low enough for belt-driven loads, and the housing follows the standard unpainted configuration to support heat dissipation. The single-ended shaft arrangement omits a shaft end on side B, which avoids additional overhang mass. In the 090 frame, length code A indicates the shortest stator stack and helps minimize weight on moving axes.
