Product Description:

The MDD090A-N-040-N2L-130PA0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts commanded current into controlled rotary motion for positioning tables, pick-and-place gantries, and other industrial automation axes. Its purpose is to deliver repeatable torque and speed so the drive system can carry out precise moves under closed-loop control.

Its active face seats against a pilot bore with a centering diameter of 130 mm, which helps maintain coaxial alignment during mounting. Standard dynamic balancing limits vibration and helps protect bearings while the motor delivers a continuous standstill torque of 3.7 Nm. The motor has a nominal speed of 4000 rpm, which suits the synchronous operating range expected by the drive electronics. Feedback is supplied through digital servo feedback, allowing the controller to read position and velocity without resolvers or analog tachometers. Power and signal plugs are located on side A of the housing, which suits layouts that route cables from one direction only. A keyed shaft transmits torque, and the standard housing protects the internal laminations.

The frame is size 090 with length code A, so it occupies minimal axial space while fitting the intended mechanical envelope. Because it is supplied without a blocking brake, stopping torque must be provided by the drive or by an external clamp when power is removed. Electrical power reaches the stator through a sealed connector, which helps keep moisture away from the connection point. The output end is supplied with a shaft seal, which helps protect the rotating interface during service. The motor has a single-ended shaft and no side B extension, which suits systems that require only one mechanical coupling.
