Product Description:

The MDD090A-N-040-N2M-130PL2 is an AC synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. The unit serves as a motor for digital drive controllers in automated machinery, delivering commanded torque and speed directly from an inverter without mechanical gearing or separate transmission elements in direct-drive axis layouts. With this role, it supports precise axis positioning, repeatable cycles, and coordinated multi-axis motion in assembly cells, processing lines, and other automated handling equipment.

Its nominal rotor velocity reaches 4000 rpm, which is the maximum speed the drive can command while retaining field-oriented control. At standstill, the motor can provide 3.7 Nm of continuous torque, giving static load support without overheating, while the integrated blocking brake supplies 11.0 Nm of holding torque during power-off conditions. Position data are generated by an integrated multiturn absolute encoder, and the drive receives this information over digital servo feedback (DSF), enabling closed-loop accuracy after power cycling. Mechanical alignment to the mounting flange is simplified by a centering diameter of 130 mm, which keeps the stator concentric with the machine frame.

Electrical power, brake supply, and feedback signals are routed through a connector that is oriented to the left, so wiring can exit the cabinet side of a horizontal axis without sharp bends and remain easier to route in tightly spaced installations. The output shaft uses a keyway, allowing positive drive coupling, and the installed shaft seal helps prevent lubricant migration into the motor interior. Standard balancing reduces residual vibration for typical pulley or coupling loads, and the housing dissipates heat by natural convection. The motor has size code 090 and length code A, which correspond to a compact stator package that leaves clearance for adjacent axes. There is no side-B shaft end, which simplifies guarding around the coupling area.
