Product Description:

The MDD090A-N-030-N2L-130GR2 is a synchronous AC servo motor produced by Bosch Rexroth Indramat in the MDD Synchronous Motors series. Designed for digital drive controllers, the unit belongs to motor size 090 and carries the compact A length code, giving it a short axial dimension without sacrificing torque density. A standard housing encloses the stator, and the front shaft end uses a standard configuration without an auxiliary shaft on side B. A shaft seal protects the output end from coolant or dust ingress during operation. The motor is intended for closed-loop automation axes that require rapid cyclic positioning and consistent motion response.

At standstill, the motor can deliver continuous torque of 3.7 Nm, allowing it to sustain static loads without thermal overload. Under rated drive excitation, it reaches a nominal rotor speed of 3000 rpm, which suits pick-and-place and feed-axis applications. An integrated blocking brake rated for 11.0 Nm secures the axis during emergency stops or power-off conditions, eliminating the need for external clamping devices. Position information is returned to the controller through digital servo feedback, enabling closed-loop commutation with high resolution. Mechanical power is transferred through a plain shaft, simplifying coupling to timing pulleys or flexible couplings. The brake and feedback arrangement supports controlled stopping and accurate position tracking during operation.

The mechanical interface follows IEC dimensions, and the mounting flange provides a centering shoulder of 130 mm for precise alignment to gearboxes or machine plates. Power and feedback conductors terminate through a sealed connector that faces the operator side, helping maintain a protected electrical interface. This right-side connection helps keep wiring inside the machine envelope and supports orderly cable routing in compact equipment. Rotor and fan components use standard balancing, which keeps vibration within normal ISO limits at maximum speed.
