Product Description:
The MDD090A-N-020-N2M-130PA2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers in automated machinery, where it converts controlled electrical input into proportional torque and speed for positioning tasks in assembly, packaging, and material-handling systems. Its synchronous design supports closed-loop operation, giving the axis responsive acceleration, stable speed control, and repeatable positioning during normal machine cycles. This arrangement also allows many medium-torque applications to operate without adding external gearing.
At a nominal speed of 2000 rpm, the rotor can maintain commanded velocity on moderate-speed axes without requiring field weakening. The motor provides 3.7 Nm of continuous standstill torque, allowing it to hold a load while current is applied, and the integrated brake adds 11.0 Nm of static holding torque when power is removed. Position data is returned through Digital servo feedback (DSF) from an integrated multi-turn absolute encoder, so the connected drive can track shaft position over multiple revolutions and start without a homing cycle. A centering diameter of 130 mm helps align the flange accurately during installation, while the standard balancing grade supports smooth running at rated speed. The installed blocking brake secures the shaft at rest, and the shaft seal helps keep lubricants contained and contamination away from internal components.
The motor uses Motor Size 090 with Motor Length Code A, giving it a short housing that fits applications where mounting space is limited. Power and feedback conductors exit on Side A through a rectangular connector, which helps reduce cable bending inside compact machine frames and simplifies routing near the motor face. The shaft includes a keyway for positive torque transmission, and the design uses a single shaft end with no side-B extension. The housing is standard cast aluminum with an unpainted finish. This layout is suitable for direct connection to digital drive controllers in machines that need compact installation and reliable holding at standstill.
