Product Description:

The MDD090A-N-040-N2L-130PL1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat in the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into precise rotary motion for automated axes. The size 090 frame and motor length code A create a compact package for medium-speed positioning on assembly, handling, and packaging equipment. This layout suits installations where accurate motion is needed without using a larger motor housing.

At its rated operating point, the rotor reaches a nominal speed of 4000 rpm, allowing fast motion on positioning axes. During standstill, the electromagnetic circuit develops 3.7 Nm of continuous torque, which supports closed-loop holding against steady loads. A normally closed blocking brake supplies 6.5 Nm of mechanical holding torque, so vertical or suspended axes can remain locked when power is removed. The motor flange has a centering diameter of 130 mm, which helps align the housing on gearboxes or machine plates. The shaft is provided on side A only, so there is no side B extension. Power and encoder signals are returned by digital servo feedback, and torque is transmitted through a keyway shaft end to reduce coupling slip during repeated reversals.

The motor uses standard balancing, which helps keep vibration within normal operating limits at rated speed. Cables exit on the left side, which can simplify routing where the motor is mounted close to guarding or adjacent machine members. The motor uses a single connector for power and feedback connections, reducing the number of separate cable entry points at the housing. A shaft seal at the output end helps keep coolant splash and airborne particles away from the front bearing area. This arrangement supports use in enclosed machine spaces where contamination control matters during routine operation.
