Product Description:

The MDD090A-N-040-N2L-130PR0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended to deliver precise rotary motion and position data to numerically controlled machine axes and automated handling modules. The motor works with compatible Indramat drive amplifiers, allowing closed-loop torque and velocity regulation during repeated indexing and contouring moves. This operating concept supports stable response in machinery that depends on accurate starts, stops, and speed changes.

The unit develops a continuous standstill torque of 3.7 Nm, giving the drive adequate holding force and low-speed output without overheating. During regular operation, it can reach an upper rotational limit of 4000 rpm, which indicates the maximum operating speed expected from a compatible inverter-driven system. Shaft alignment on the machine frame is guided by a centering pilot of 130 mm, which helps simplify concentric mounting and reduce vibration. Power and feedback cabling exit the stator housing on the right side through a single connector, which keeps routing concentrated at one point on the motor housing. Dynamic response is supported by standard rotor balancing and internal digital servo feedback, which returns high-resolution position data to the controller.

The motor uses frame size 090 and length code A, giving it a compact body that fits shallow installation depths while the standard housing relies on convection cooling. A keyway shaft transmits torque, and the shaft end is supplied in a single-ended configuration, so there is no extension on side B. The design comes with a shaft seal, which helps protect the bearing area in vertical mounting positions or in installations exposed to splash. Because the motor is delivered without a blocking brake, any required static holding force must be provided by the drive or by an external brake module.
