Product Description:

The MDD090A-N-040-N2M-130GA2 is a brushless AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. As a motor intended for digital drive controllers, it converts controlled electrical power into precise rotary movement for automated positioning, packaging, and material-handling axes. Its design combines an internal permanent-magnet rotor with electronic commutation, creating a compact actuator that maintains consistent velocity and torque over a wide speed range in closed-loop industrial systems. The series uses consistent mechanical dimensions across multiple frame lengths.

Rated for a nominal speed of 4000 rpm, the motor can track rapid command changes without losing electronic synchronization. At standstill, it supplies a continuous torque of 3.7 Nm, enabling low-speed holding tasks such as indexing tables or lightly loaded gantries. A factory-installed blocking brake provides a static holding capability of 11.0 Nm, so vertical loads remain secure when power is shut off. Position data comes from an integrated multiturn absolute encoder, while velocity feedback is transmitted to the drive through digital servo feedback. This combination eliminates the need for external resolvers and supports high-resolution motion profiles.

The motor uses the 090 frame with length code A, and the stator body uses standard balancing for vibration control. A centering pilot of 130 mm aligns the flange to gearboxes or machine plates. Power, brake, and feedback conductors exit through a single connector on Side A, which simplifies cable routing in compact cabinets. The drive end is a plain shaft with standard keyless geometry, and there is no secondary output on side B. A fitted shaft seal protects the internal bearings from coolant or dust ingress. Standard housing surfaces allow natural convection cooling when the motor is mounted inside sealed automation cells.
