Product Description:

The MDD090A-N-020-N2L-130PB0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. With motor size 090 and the compact A length code, it is suited for applications that use digital drive controllers for point-to-point positioning and cyclic speed regulation. The motor delivers rotational power directly to machine axes, and its integrated encoder interface allows the drive to maintain precise torque and velocity control during operation. This arrangement supports accurate motion in automated equipment where repeatable response and stable closed-loop performance are required.

The centering flange measures 130 mm, which helps the motor seat accurately on gearbox or machine-frame bores. At standstill, the motor can deliver 3.7 Nm of continuous torque for steady operation without additional cooling hardware. Under rated excitation, it reaches a nominal speed of 2000 rpm, giving the axis a practical base speed for common transmission ratios. Power and feedback leads exit on Side B, which can simplify cable routing when the shaft faces the operator. A sealed circular connector carries both power and signal conductors, and the housing uses the standard enclosure style with a single-ended shaft arrangement to keep the mechanical layout straightforward.

Closed-loop operation is supported by digital servo feedback, which provides high-resolution position data to the connected drive. The motor is supplied without a blocking brake, so applications that require passive holding torque must use an external clamping or holding device. A fitted shaft seal helps protect the bearing set when the flange area is exposed to coolant spray or routine washdown conditions. Torque is transmitted through a keyway shaft, which works with keyed couplings to reduce the chance of slip during reversing duty cycles. The rotor is also dynamically balanced to a standard grade, helping the motor run smoothly in normal servo applications.
