Product Description:

The MDD090A-N-030-N2L-130PA0 is a synchronous servo motor built by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Delivered for use with digital drive controllers, it converts commanded current into controlled torque and speed for automated axes in assembly lines, packaging modules, and material-handling stations. This arrangement allows the associated drive to regulate torque, speed, and position in real time during synchronized motion. The motor is intended for applications that require repeatable response during frequent starts, stops, and short positioning cycles.

Its continuous torque at standstill is rated at 3.7 Nm, so the shaft can hold load at zero speed while the windings remain energized. During motion, the rotor reaches a nominal speed of 3000 rpm, providing a common operating point for positioning and repeated cycle duty. Mechanical alignment is aided by a centering diameter of 130 mm, which helps seat the motor accurately against adjoining machine parts. The rotor is balanced to the standard class to reduce vibration across the speed range. Electrical and encoder leads exit on Side A, and torque is transmitted through a keyway shaft for keyed couplings. This cable orientation can simplify routing when the connection point must remain on the same accessible end of the motor.

Power and feedback cables connect through a front-mounted connector, which keeps the interface accessible at the front of the housing. The motor is supplied without a blocking brake, so any holding function at standstill must come from the drive or from external machine hardware. It is fitted with a shaft seal to help protect the bearing area from contaminants, and the shaft remains a single-ended design without a side-B extension. The frame size is 090 with length code A, giving the unit a compact mechanical envelope for digital servo applications. This layout can help reduce the overall installation length in machine sections where available space is limited.
