Product Description:

The MDD090A-N-040-N2M-130GB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. It is intended for use with digital drive controllers on axes that require coordinated speed and position control in production machinery, packaging lines, and automated handling stations. Its frame size, shaft arrangement, and integrated feedback allow direct connection with compatible Indramat drive modules for closed-loop motion applications.

The motor delivers a continuous standstill torque of 3.7 Nm, which is the torque it can maintain at zero speed during continuous operation. At rated operation, it reaches a nominal speed of 4000 rpm, which supports fast indexing on light-to-medium inertia loads. Mechanical alignment is aided by a 130 mm centering diameter that fits standard Indramat mounting flanges. Power and feedback conductors exit on Side B through a sealed connector, which helps keep cabling away from the load side. Rotor position is monitored by an integrated multiturn absolute encoder, so the control loop can track shaft position over multiple revolutions without a homing cycle. The motor uses a standard balance grade, a standard housing, and a compact A length in the 090 frame.

The motor is supplied without a blocking brake, so any application that requires holding torque at standstill must rely on external holding hardware or drive-based torque holding. Position information is transmitted through digital servo feedback, which supports stable signal transmission and immediate detection of feedback faults by the controller. The drive end uses a plain shaft, and a factory-installed shaft seal helps protect the interior from coolant splash and airborne contaminants. The connectorized cable arrangement and standard housing support straightforward integration in typical industrial installations.
