Product Description:

The MDD090C-N-040-N2L-130PA0 is a three-phase synchronous motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It operates as an electromechanical actuator in digital drive systems, translating current from compatible controllers into regulated shaft rotation for packaging lines, pick-and-place arms, and machining spindles. With its 090 frame size, C length code, and standard housing, the unit balances compact dimensions with the thermal capacity required for continuous duty. A permanent-magnet rotor and closed stator slots help produce smooth torque across the speed range for repeatable positioning in multi-axis assemblies.

A centering pilot of 130 mm allows rigid flange alignment to gearboxes or machine frames. At standstill, the motor can exert 10.4 Nm of continuous torque, a level supported by the internal thermal path of the aluminum frame. Dynamic operation reaches a nominal shaft velocity of 4000 rpm, enabling high cycle frequencies when coupled to low-inertia loads. Power and feedback conductors exit on Side A of the housing, and the plug-in connector arrangement simplifies wiring because no permanent pigtails are required. Balancing is standard, so vibration remains within general-purpose limits over the speed band.

Rotor position is monitored by digital servo feedback (DSF), which supplies position data to the drive for closed-loop control. A shaft seal at the output journal protects the interior bearings from coolant splash or dust, while the keyway shaft profile permits direct coupling of pulleys or pinions without additional machining. Because the motor is supplied without a blocking brake, axes that require static holding torque must rely on external clamps or continuous drive excitation. The single output shaft and the omission of a side-B extension reduce overhang and leave space for guards or sensors mounted close to the motor face.
