Product Description:

The MDD090C-N-040-N2L-110GL2 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed to operate with digital drive controllers, the motor supplies commanded rotary motion for positioning and velocity tasks in industrial automation cells. It combines an integrated brake and encoder to support closed-loop control and secure load holding during power-off events. This arrangement is well suited to axes that require repeatable motion during operation and controlled stopping behavior when drive power is removed.

Under rated conditions, the motor reaches a top shaft speed of 4000 min⁻¹, which supports high-cycle operation with fast motion sequences. At standstill, it can generate 10.4 Nm of continuous torque, allowing the axis to resist static loads without overheating. The blocking brake adds holding capacity of 11.0 Nm, helping keep vertical or suspended loads in place when power is removed. Position feedback is delivered through Digital servo feedback (DSF), giving the drive the rotor data needed for accurate commutation, speed regulation, and position control. Mechanical alignment is supported by a centering pilot of 110 mm, which provides a consistent reference surface for mounting to the machine interface.

Wiring is routed to the left face through a connector, which keeps the electrical interface compact at the motor housing. The output uses a plain shaft so it can be coupled with standard clamping hubs and similar drive components. The motor has length designation C and frame size 090, which indicate its magnetic stack and overall package size. Standard housing geometry supports convection cooling, and a shaft seal helps limit lubricant escape around the output interface. The rotor is balanced to a standard grade so vibration remains controlled during routine motion cycles.
