Product Description:

The MDD090C-N-040-N2M-110PR1 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended to pair with digital drive controllers and convert commanded current into mechanical rotation for axis control in automated machinery. By integrating the motor, feedback, and brake into a single housing, the unit serves as a compact actuator for packaging stations, printing modules, and handling axes that require precise speed regulation and repeatable positioning.

At standstill, the motor can supply a continuous torque of 10.4 Nm, and it reaches its rated operating velocity of 4000 rpm when the winding current matches the controller’s nominal output. A centering diameter of 110 mm aligns the housing to machine frames, while standard dynamic balancing helps reduce vibration during high-speed cycles. Power and feedback conductors exit on the right side through a keyed connector, which supports orderly cable routing in multi-axis gantries. The model uses the C length code within the 090 frame size, giving additional stack height without changing the flange pattern. A standard housing encloses the stator, and a single-ended shaft without a side-B extension permits direct coupling to gearboxes or belt pulleys. A shaft seal prevents lubricant migration into the bearings during operation under splash conditions.

For holding and feedback functions, the unit includes a blocking brake that develops 6.5 Nm of static torque to keep the load in position during power removal. Position data is generated by an integrated multiturn absolute encoder, and the drive reads this information through digital servo feedback (DSF) to allow immediate closed-loop commutation after start-up. The keyed shaft profile, specified as keyway, supports positive-locking couplings so transmitted torque does not slip under reversing loads.
